You need 4 D's. I know that sounds like a Rip-off, but it totallykeeps working for a long time.
The neutron has about the same mass as the proton, each hasa mass a tiny amount greater than 1 AMU (atomic mass unit). Theneutron is the smallest bit more massive. The electron has a mass of just a bit over 5/10,000ths of an AMU.Extremely less massive in comparison, isn't it!
Yes, it is made of plant fibres (cellulose which is a sugarpolymer) so it has chemical energy which will be released as heatif it is burned. It also has mass and that mass harbours potential energy in anygravitational field. If it falls towards the ground for anydistance this potential energy will...
Usually we use a mechanical or electrical meter. Gas supplies cansimply drive round a counter. Electricity can be measured inseveral ways, for instance by using part of it to turn a disc whichin turn drives a counter. Essentially we measure how much power weuse and for how long. The unit is usually...
Fluorescent materials are used in illumination, displaying, solidstate lasers,light communication,light memory and so on.
The electrical resistance between subatomic particles is farreaching from the atomic nucleus and electron cloud. Electrons arealso moving very fast. The probability cloud that determines wherethe electrons could be, the orbitals and the nucleus itself, arestill not solid objects. Keep in mind under...
The electromagnetic and strong nuclear forces are very powerful andrepulsive at close ranges. Put two atomic nuclei near each otherand they will push away from each other. Similarly if you put twonegatively charged particles near each other they will also repelat very close distances.
Energy is associated with power and motion, and matter isassociated with everything physical. Both are types of sciencevocabulary.
See the recordings of temperature over the last 10 or 20 years.This could show an increasing temperature. Also, you could see howmuch of the ice has melted or the rise of sea level (not to beconfused with tides). If the Earth is getting warmer, then moreicecaps would melt, resulting in higher oceans...
54 km per second is equal to 120,794.56 mph
Depends. Whats the amperage rating on the bulb and the battery? Isthe 12 volt bulb LED? The equation to find your answer depends onhow much your 12 volt bulb is drawing and how much your batteryhas. I have seen 12 volt bulbs that are searchlights and I haveseen 12v bulbs that are little LED ones....
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit...
The red line goes down and the blue line just goes all the way up.Cool right?
It's not the only reason, but the same force will produce lessacceleration in a body with more inertia.
As long as the electricity is static, it is of little concern. Ofcourse, static today, current tomorrow. If you are in contact with a large static charge and also with theEarth, the energy can flow through you, and there might be enoughto stop your heart. I heard of a man who picked up two cables...
In hot metals the kinetic energy of electrons becomes higher andthey move randomly so their movement in one direction becomesdecreased so the conductance becomes decreased.
A: assuming a infinite current source the current will increase accordingly
The specific gravity for water is 1. .
However, when the temperature of water increases, the gravitygradually lowers. At 0Â°C (32Â°F), gravity is 1. At 100Â°C (212Â°F),the specific gravity of water is 0.958. At 300Â°C (approx. 580Â°F),it is 0.7.
Protons and neutrons are called hadrons. A hadron contains threequarks. Quarks come in 6 flavors (types). These types are up, down,top, bottom, strange, and charmed. (The names are completelyarbitrary.) A proton contains two up quarks and one down quarkwhile a neutron contains one up quark and two...

Conduction, convection and radiation. Conduction is when heat is transferred directly between materials. convection occurs when heated materials move from one place to another heating matter along the way. Radiation is when waves of heat move through space.
Intensity (brightness) and energy (frequency).
Electricity tends to prefer paths of least resistance, as doeswater and air.
Gravitational density. And on the atomic level it would be how densely packed the particles are. Some approximate values: Water: 1000kg/mÂ³ Earth or rock: 5500kg/mÂ³ Neutron star 5Ã10 17 kg/m 3
It isn't an object which can be found of itself, but objectspossessing angular momentum are those which are turning.
same as with anything?!?!
Perhaps it was the M65 atomic cannon, a 280 mm towed gun that fireda nuclear tipped projectile.
it describes the plasma state.
Pressure is given by the formula P = h * d * g Here h is the depth or height of surface right from bottom. Givenas 3.5 m d = density of water i.e. 1000 kg/m^3 g = 9.8 m/s^2 You could plug and get the value of P at bottom in pascal
It doesn't just happen in space. Stick out your thumb and look atthe background; as you move your hand toward you, the greater theparallax shift.
The angle of reflection (Î¸ r) off a planar surface (eg. mirror) is equal to the angle of incidence (Î¸ i ) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as...
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An...
As the material body travels at the speed of light its relativisticmass becomes infinite. Hence the kinetic energy too becomesinfinite which is not practically possible
Mechanical Advantage = Length of Slope / Height of Slope ( MA = L/H) so if the Length you refer to is the length of the slope then MA= 6 / 2 = 3. However, if the length you refer to is the length of the ramp fromend to end (rather than measuring the length of the slope) then youfirst need to...
Gravitation follows an inverse square law, so a gravitational fieldwhile eventually small enough to be negligible will never benon-existent.
Reflection, refraction, and diffraction. Reflection is most common, when we see ourselves in the mirror. Refraction is evident when you insert a straw into a clear liquid (7-up, for example) and see the straw bend at the surface apparently. Diffraction is when light passes through a slit or opening,...
Ice near its normal freezing point has a larger volume than liquidwater at the same temperature. If you put pressure on ice it willbecome smaller by becoming liquid.
The resulting phenomenon is known as constructive interference.
Yes. The LR-20 is a D-sized 1.5-volt alkaline battery. The batterynumber for Duracell is MN1300.
It depends on the size of the magnent
In a sense. If you are far away from an event you may see it beforeyou hear it.
Mechanical advantage has no unit, because you are dividing a forceby a force. It is simply a dimensionless number.
Generally speaking, yes. As a general rule, the larger the bell, the lower it's pitch will be.

Specular reflection is the mirror -like reflection of light (or of other kinds of wave ) from a surface, inwhich light from a single incoming direction (a ray ) is reflected into a single outgoingdirection. Such behavior is described by the law ofreflection , which states that the direction...
Interesting question.. In all reality one human cannot drain another humans energy for their benefit.. BUT techincally it is possible. Ex. A king working his slaves to death That is a way of draining someones energy. You may also find ancient religions that say its possible through black magic or...
In addition to Mr. Al Cohen's Expert answer I will add that670,616,629 miles per hour equals about 11,176,943 miles per minuteor 186,282 miles per second.
each newton of force equals 9.8 pounds .
I am afraid you have mixed both units and systems there. Theyhave equivalents but are not equal. .
The Newton is a unit of Force or "weight", not Mass. .
The Kilogramme and the Pound are units of Mass, not Force, andby totally different systems of...
Heat causes the molecules in a form of matter to accelerate (reasonwhy ice becomes water, and water becomes gaseous water vapor).
energy can not be lost it can only be transported into other things
Friction always opposes relative motion. It does not oppose motion. Friction is an electric force. It starts acting when two surfaces rub each other. Say a block is pushed and then released, it gets an initial acceleration and its speed starts increasing. Here friction starts playing its part....
SCIENCe wavelengths .
Yes, there are. If youre talking about electromagnetic radiation, they have the same speed 3*10 8 They vary in wavelength (greek letter lambda) and frequency to maintain this as speed of light= wavelength * frequency You'll find this in an Electromagnetic spectrum....

The SI unit is the kilogram per meter (kg/m).
grams are a measure of mass and density is mass per volume, soneither are greater because neither are density values.
O-16 + He-4 ---> F-19 + H-1 Hence fluorine nucleus is produced.
The range of all forms of radiant energy is called theelectromagnetic spectrum. It ranges from extremely long radio wavesto extremely short gamma rays.
Electron capture is the absorption of an electron by an atomicnucleus if that nucleus is neutron poor. An electron is captured,usually from an inner electron shell of that atom, and it willconvert a proton in the nucleus into a neutron. We know that aneutron is converted into a proton and an...

Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens. Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel...
velocity cause Velocity= wavelength X frequency
Otherwise everything would be dark, and we would have to rely on sound or touch for navigation.
Molecules that are in a solid are constantly moving around andvibrating. All states of matter possess molecules in them.
When you are looking in a mirror, you are looking at your reflection. Light that is hitting the mirror is bouncing back, making you able to see yourself in the mirror.

concave mirrors are used as rear view mirrors and serve dentistsand used as reflectors
If fired with the same momentum yes it does effect the penetration
Half life has unit. That is unit of time. So it has to bementioned. Let us assume that half life is 1 year. Okay. Now toknow about the mass remaining we have to get the ratio(1/2)^ 1620. Hence remaining will be 1/(2^1620) * mass at thebeginning
Telephones converts sound into electrical signals, and backwards.Speakers with dynamic-coil transdusers convert electrical signalsinto sound by using the properties of electromagnetism.
Also, by electron charge, are you referring to the opposite ofelementary charge? The systematic name is monohydrogencarbonate(-1), this tells you the formal charge, as would simplyadding the charges using the chemical formula of bicarbonate.[HCO3]-
The first is hydrogen, and the second is helium, they make up 97% if the mass if the stars.
Frozen batteries last longer unfrozen batteries.
lithium batteries have a faster current discharge rate thenalkaline batteries but they cost more. The LIPO battery is used themost in RC planes.
There is a little clip that holds it in. Look at the circle, at some point around it,you will see a small clip, you push it away from the battery and it will allow the battery to come out. Now, when you touch a motherboard, you are suppose to wear a anti static strap, and remove all power...
Alpha particles consist of 2 protons & 2 neutrons. These particles, then, have charge +2
We should never say that an experiment has proven something. The Rutherford gold foil experiment led to the hypothesis that an atom's positive charge is concentrated in an incredibly small space at the atom's center.
The light bulb gives light be heating the filament. Roughly speaking, it is emitting black body radiation. Plank's Law gives you the formula. See here: http://en.wikipedia.org/wiki/Black_body http://en.wikipedia.org/wiki/Planck's_law
Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different...
most common answer; 0. .
The '0' value is correct - a constant speed or velocity (notsynonyms) is one of no acceleration or deceleration - but it's notthe "most common" answer, it is THE answer! :-)
Electrons are a type of fundamental particle known as a Lepton.Protons how ever are made up of quarks. A proton has a quarkstructure of up, up, down (UUD). The up quark has a charge of +2/3and the down has -1/3 which gives the proton its overall positivecharge. The up and down quark both have a...
Condensation of water vapour.
You mean, what happens when positive and negative charges are equal? That is simple, the equal opposite cancel each other out and we have an electrical neutrality
Given a line L and apoint P. Reflection P' of P in L is the point such that PP'is perpendicular to L, and PM = MP', where M is the point ofintersection of PP' and L. In other words, P' is located on theother side of L, but at the same distance from L as P. P' is saidto be a mirror or symmetric ...
Purple. In a prism, the higher energy light gets bent more. There is a disagrement about the name of the light -- it's either purple or violet. Physicists used to say violet. Psychologists used to say purple. It is the same light with different names, depending on the group.
