A toaster is just a box with resistance coils in it. In order forthe coils to heat up and burn bread, current electricity must pass through them forsome time.
On a dry day, put on shoes with rubber soles. Than scrub and scruffyour feet on a nice stiff scratchy carpet for about two or three minutes,then immediately walk over to the person who's getting your precious gift, reach outyour pinky finger, and touch them on the ear-lobe. They will absolutely...
It is the force constant of the material in N/m. So you can substitute it into the equation F=kx (F=force, k=force constant or gradient in N/m, x = extension) You would expect the extension to be on the y-axis normally since it is the measured value. However since you want to use the graph to...
Older members of population, particularly fecund ones, in pairs, are sources of younger individual members.
You must be sitting twice as far away from the pivot, on your side, as your sister is on her side.
No, but if it is hot you will be burned
Probably not to you or other people. But it can damage sensitiveelectronic things. And if it doesn't kill them right away, it can shorten thelife of some electronic components, so that the device dies sooner than it wouldhave.
Over a long period of time, the average daily number of interments must be equal to .
(average daily deaths) minus (average dailycremations)..
the mean free path in dependent on pressure, since the mean free path equation state that mean free path=k*T/((2)^(1/2))*P*o so if you double the pressure your actually decreasing the mean free path by half.
find the tangential slope at the time intervals and you will get velocity.. then just plot it on the graph
The mean is that number which, if every member of the group werereplaced by it, the effect or characteristic of the group would not change.
That's actually only possible in a First Class lever. In that case,moving the fulcrum closer to the load makes it easier to lift the load, sinceit now takes less force at the effort end. But the effort force also has to movethrough a greater distance than it did before, in order to lift the load...

Static generators, such as the Wimshurst and the Van deGraaff, bothseparate charges by rubbing/scraping one surface against another. Theydiffer in how they store the charge before the zzapp occurs.
The shock will travel to your brain. It will also make your hair stand up
I've got to assume that your ' i ' and your ' j ' are the samething. .
Vector A = j3 .
Vector B = -j1 .
The angle between them is (pi).
The parallelogram law of forces can be applied to any situationwhere multiple forces are acting on an object. The launching of astunt person from a cannon in a circus is a prime example. Toachieve a certain angle of launch with a certain velocity, aninitial velocity must be applied to the person,...
The answer is in Mrs. Hyders class room.
1 Liter (L)= 1000 milliliters (mL) Divide 1 L by 1000mL, then multiply by 4. This gives you .004 Liters.
the nozzle of the spray painter is given a positive charge which in turn induces a negative charge on the paint droplets.these repel each other and are attracted to the car body which is earthed to remain with a positive charge.hence the drplets are evenly distributed across the car frame.
4d as in four dimensions have never actually been made. It is always present. Have always been present. Will always be present. Three dimensions we consider on a day to day basis is length, width and debth. Knowing these variables makes it possible to calculate positions in space. By adding a...
A sequence of variables in which each variable has a different variance. Heteroscedastics may be used to measure the margin of the error between predicted and actual data.
In the rock layer, the layer at the bottom is the oldest... the one on top of it is youngest rock. Later one sediments can be brought to the top of the rock by weathering and erosions and then after a while it will become rock and the new layer will be the youngest.
The economic concept of elasticity measures how buyers and sellers respond to shifts in market conditions, such as price changes. The terms "elastic" and "inelastic" describe how the level of supply or demand shifts in response to a change in price. IDENTIFICATION:If a change in price leads to...
The fact that the particles of matter are in continuous motion is a blessing in disguise. If matter particles did not move then if a harmful gas leaked, the vapours of the gas would remain stationary in a place. This would make that place more polluted and poisonous than its surroundings. Particle...
Static is a keyword which is used to call the methods or variables without creation of that class object. It will directly calls the respective method and varialbles.

You can move things with static electricity!
According to research made at multiple websites; Mugenda and Mugenda, which is a company that focuses on research methods for various areas, define sample size by using statistics data and probability.
You can teach at the high school or college level. You can work in experimental design, or develop new technology. Most rocket scientists come from the field of physics, as did those who work on nuclear weapon systems and research, those just being a few examples.

Nothing happens to the person's center of gravity. But the CG of the (person + books) combination is to the right of the CG of the person alone. Also possibly above it if the person is female, and possibly below it if the person is male.
multiply coefficient of static friction by object mass
Resultant Force =( Force1 ) +( Force2 ) +( Force3 ) where each term in the formula is a Vector.
Actually, the static friction is never zero.
An experiment is almost always designed so that two (and no more) things will change. -- You, the experimenter, will change one of themas you desire. -- That will cause a change in the other one,which you will carefully measure.
salt and water is a conductor
The actual goal of this particular facet of quantum mechanics is to calculate all of allowable energy states, not just the ground state. The ground state is significant though since it's the energy that the system is always trying to get to.
Due to the heat, some of the mass was carried off in the form of soot and gases.
That's called "Archimedes' Principle", after the ancient Greek philosopher who discovered it.
they are 2 or 3 forces acting at same point and which are of same nature
yes, anything with a lower atomic number would be lighter, for example, helium is lighter than air, which is why balloons float when filled with helium... the lighter substance rises above the heavier....
Density of a knife = (mass of the knife) / (volume ofthe knife)
it is the roughness or smoothness between two surfaces
If an investigator said that mathematics is the backbone of physics, there would arise little argument. Physics is the study of matter and motion. (Energy, too.) That's a broad statement, but physics is a broad area. And mathematics is used in most all corners of it..
When we apply scientific method...
They were "engaged in the direct production of commodities." See Sean Wilentz, Chants Democratic p. 27, n. 13.
The resultant doesn't tell you anything about the component forces. Often, you can't even tell whether there are anycomponent forces, because the resultant behaves just as if it were the one and only single force present.
Because an object immersed in water is buoyed upward by a forceequal to the weight of the displaced water, so the stone's net weight inwater is less than it is in air, by a difference of roughly 62 pounds for eachcubic foot of its volume.
No. It will be exactly the same, in every detail, as if you hadpaid cash for it.
The more mass an object has, the more friction it will have. The less mas an object has, the less friction it will have.
No, because the amount of force you have applied to the rock cancels with the reaction force from the rock pushing back. Action- reaction. Think about the different types of energy you need to consider: Â½mvÂ² mgh and possibly rotational Â½iÏÂ² Have you given the rock any of these things...
It does not very significantly because melting does not involve gas-phases molecules. Boiling, on the other hand, is strongly affected. See the Related Questions for how the boiling point of water is affected by air pressure.
Volume of liquid displaced = Volume of object submerged
Basic properties of friction have been described as laws : .
Amontons' 1st Law : The force of friction is directly proportional to the applied load. .
Amontons' 2nd Law : The force of friction is independent of the apparent area of contact. .
Coulomb's Law of Friction : Kinetic friction is...
No. The slope would have to be shorter than the height.
As the plane hits the deck, its kinetic energy is 1 / 2 (its mass) x (its speed) 2 , so that's the amount of energy that has to go somewhere in order tobring the plane to a complete stop where its kinetic energy is zero. My guess at the moment is that the energy must be dissipated in onehumongous...
There have been a lot of claims that this physical feature or that affects intellectual ability, and maths in particular. Some claim that race matters, gender, head size, body size, you name it. Now, let's ignore things that really can matter, such things as undiagnosed and uncompensated problems...
The question makes no sense. Objects are buoyant in a surrounding fluid; change the fluid, change their buoyancy.
2pie r T cos theta = pie r2(r squared)h rho g which gives............ T = 1/2 rho grh if r is small if r is not small,,put h=h+r/3 :D
No work is taking place and no energy is moving outside of yourbody. The movement of energy is all in your muscles, and it getsdissipated as the sweat trickles out of your skin and evaporates into the air.
The density of gold is 19.3 g / cm 3 . 0.014 gram / 19.3 gram /cm 3 = 0.0007254cm 3 (rounded)
yes it does but only under extreme and special conditions...
Not at all. It's nominally proportional to the area ofcontact.
The friction between two objects, fabrics, or surfaces may move electrons from one of them over to the other one.
Coplanar or not, the two conditions for equilibrium are: .
The sum of all forces must be zero .
The sum of all torques must be zero.
They are not. They're run by current electricity, that comes from the power company and through the meter outside your house.

static friction, friction between two non-moving objects.
As the air bubble increases in volume, its mass remains constant.Because the mass remains constant but volume increases, densitywill decrease.
well,in some situations the presence of static electricity can be a disadvantage..
For an example:-.
