Mechanics

Parent Category: Physics
Mechanics is the branch of physics that deals with the interactions of objects and forces in the observable world. Questions asking about projectile motion, conservation of energy, and calculus based mechanics are perfect for this topic, but questions about repairs that a mechanic would do belong in our vehicles categories.
54 km per second is equal to 120,794.56 mph
A: actually any active components will oscillate with positive feedbackA 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?
Usually in orbits unless it is artificial
As the material body travels at the speed of light its relativistic  mass becomes infinite. Hence the kinetic energy too becomes  infinite which is not practically possible

The term "simple" and "compound" machine refer to physical devices  that transform work. The computer is an electronic device whose  main operation has no moving parts whatsoever. Any motion within  input and storage devices is controlling electrical components, not  mechanical ones.
With poor language we cannot assess. Any way the objects speed goes  on increasing
Data representation. Cumulative frequency is the sum of all previous frequencies.
A local oscillator can be a crystal oscillator.
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency...
The wavelength of light times the frequency of light is its speed, which is close to 2.9979*108 m/s in most mediums.
Every application is different, you will need to look up the torque  values for your engine serial number
Simple harmonic motion is understood from an oscillating pendulum.  It is also periodic. An example of periodic motion without simple  harmonic motion is the rotation of the blades of a fan.
A simple pendulum has one piece that swings. A complex pendulum has  at least two swinging parts, attached end to end. A simple pendulum  is extremely predictable, while a complex pendulum is virtually  impossible to accurately predict.
I have no video but electromagnetic wave may harm and may not   It is divided to seven the radio  waves,microwave,infrared,visible light,ultraviolet light,X-rays,and  lastly Gamma rays. The waves that is not harmful is from radio wave  to visible light then the rest may harm
The specific heat capacity of motor oil is 2 Kj/ Kg. That means 2  kilojoules and kilograms which is how heat is measured.
v=fλ Visible light is an electromagnetic wave. All electromagnetic waves travel at 3.0x108 m s-1 in a vacuum. Since the question doesn't supply additional info I'm assuming the medium is a vacuum. Hence, v=3.0x108 m s-1 and λ=486x10-9 m. Therefore, f=v/λ = 6.17x1014 Hz
The rate constant is something that must be solved for in each  individual equation. Without more information, it is impossible to  answer the question completely.
I posted this earlier. weather the van is in gear or out of gear, driving or braking, as soon as it pass 50 mph it starts to make clunking noises from under the engine. not particular to one particular place but mostly from under the passenger footwell, then under the engine itself and sometimes a...

Sound wave travels from one part in to another part in air due to  change in density of molecules from one point to another point
The total of all electromagnetic waves is called the  electromagnetic spectrum.  The electromagnetic spectrum includes radio waves, microwaves,  infrared radiation, visible light waves, ultraviolet radiation,  x-rays, and gamma rays. Only visible light waves, which humans see  as the band of...
No. Otherwise it is no standing wave.
Frequency of em radiation is inversely proportional to its wavelength.so, frequency increases with decrease in wavelength.
Assuming that "r" is the radius, that simply isn't sufficient  information to calculate angular velocity.
The math that describes them, Fourier transforms allow one to add wave functions. Also thr fact that they are waves so wave adding together or "cancelling " each other out is possible, wave interference both constructive and destructive does occur.
To convert from miles to kilometers, you multiply by 1.6. Same  thing, to convert from miles per hour to kilometers per hour.
30,000 feet per hour = 5.68 miles per hour.
A net force on a body can stop the motion of a body , can create  the motion of a body and can change the direction of motion of a  body .
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
A: Very easy to do just provide a positive feedback and/or a phase shift it will oscillate
Vf = Vi + at   Where Vf = final velocity   Vi = initial velocity   a = acceleration   t = time
It will become longer, and it will carry less energy, its also  likely, that if the change or loss in frequency is enough, the  radiation will become a different type of electromagnetic radiation  in the spectrum like gamma to x-rays or visible light to infrared  and so on.
Sound waves are vibrations through a medium, such as air or water. The energy travels from the vibrating source and vibrates molecules in the medium, which push others sending a wave through the medium. Without a medium, there's nothing to vibrate and sound cannot travel.
wavelength. The larger the frequency, the smaller the wavelength.
Well you can always work out the normal force... if the object is  on a horizontal surface... The normal force is equal to the mass of  the object × gravity (9.81). If the object is on an incline, you  have to get the component of weight which is equivalent to the  Normal, in most cases it is...
In an isolated system the total momentum of a system remains  conserved. For example If you fire a bullet from Gun , bullet go  forward with some linear momentum and in order to conserve the  linear momentum the gun recoils
V=f *lambda where v = wave speed, f=frequency and lambda=  wavelength.  Frequency increase as the energy of a wave increases because  E=hf where h is a constant so E/h=f. if E increase f has to  increase.  Wavelength decreases because if the frequency increases the  wavelength would also have...
Yes the kinetic energy of solid increases resulting in increase of  vibration of atoms in their mean positions
Longitudinal waves require a medium to propogate . Example are  sound waves
Though it is not possible to get a mathematically perfect square wave from a sine wave, it is possible to get a reasonably close square wave from a sine wave. A clipper circuit is one which clips off the top of a sine wave thus giving it a flat top. Clipper circuits find their applications in...
Slope of speed vs time graph = acceleration.
An increase in atmospheric __o[   ___ leads to an increase in the greenhouse effect
mgh = 10 x 10 x 10 = 1000 J ( Assume g value as 10 m/s2
About 5 minutes 21 seconds at that rate of travel.
Yes,The speed of sound in dry air is approximated by the equation:v = (331 + 0.6*T) m/swhere T = temperature in degrees Celsius
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
Average acceleration during a period of time is (change in speed) divided by (time for the change). A = (98 - 121) / (12) = 23/12 = -1.9167 meters/sec 2 average during the 12 seconds.
And what is the question? And what is the question? And what is the question? And what is the question?
Anything in the electromagnetic spectrum. Gamma raysXraysUltravioletVisible LightInfra-redMicrowavesRadio WavesThey are characterised by the fact they are all transmitted in packets of energy called photons. Sound is not an electromagnetic wave, nor is ultrasound or any physical oscillation.
The type of wave the kink in a lasso travels as is a "longitudianl wave".
Temperature is the measure of average kinetic energy of all the  atoms and molecules in an object
The sum of potential and kinetic energy gives you the Mechanical  Energy of the system
The concept of inertia requires that a body maintains its state of  motion, unless a force is applied to it. So, the presence of  friction force in nature causes the body to cease its moviment , as  expected by the first law. Thus, the analysis requires an  abstraction though, in the sense that...
The first law of Newton is for any material, and it states that if  the net force on an object is zero, the object will be at rest   forever or will move with uniform velocity forever.   In the case of a bicycle, the obviously known forces are  gravitational force, the reaction force of the...
Angular momentum = r x p... That is position vector r, CROSSED (not  multiplied) with momentum vector p. So, to find out the direction  the angular momentum will act, take ur right hand, point your  fingers in the direction of r, and "curl" (close/bend whatever u  wanna call it) ur FINGERS (not...
In any circular movement, including driving in a curve, the  centripetal force (and the corresponding centrifugal force, which  is often considered a "fictitious force") will increase:   * When the speed increases   * When the radius of curvature decreases
It's a bit complicated to list here so please follow the related link below.
Thermodynamic average energy of ideal gas in 3D is 3/2kBT. kB is the Boltzman constant, and T is the temperature in Kelvin. 
The fastest recorded so far is Usain Bolt at 27.44 miles per hour.
Amplitude. An increase in this property will result in an increase in volume of the sound.
Frequency. Electromagnetic waves are just magnetic waves that are turning into electric waves. The faster they turn in to each other, the more energy and high up on the spectrum they are.
You can calculate the centripetal ACCELERATION with one of these  formulae:   acceleration = velocity squared / radius   acceleration = omega squared x radius   Acceleration refers to the magnitude of the acceleration; the  direction is towards the center.   Omega is the angular speed,...
It depends on which reference frame you want to use. According to the reference frame connected to the crane, it will not change. According to the reference frame associated with the ground the center of gravity will of course change.
P waves are the least damaging and only travel left and right, forward and backward along the horizontal plane. S waves are the most dangerous because they cause up and down motion and travel along the surface and solids of a medium causing the most destructive force. However they do not travel as...
The frequency of an EM wave is inversely proportional to its wavelength, which can be seen in the equation f=v/λ, where f is the frequency, and λ is the wavelength.
The period of a 15MHz sine wave is 1 / 15MHz, or 0.066667 us, or 66 2/3 ns.
Newton's first law of motion says only that it takes force   to change the speed or direction of motion.
Showing that the scalar product between all pairs of them is equally zero. Two vector are orthogonal (or perpendicular) if the scalar product between them is zero. Lets see an example in 2D: If we have two vector, a = (a1, a2) and b = (b1,b2), if a · b = sqrt(a1*b1 + a2*b2) = 0 then a and b are...
Usually you would use some fact you know about the physical system,  and then write an equation that states that the total angular  momentum "before" = the total angular momentum "after" some event.
It is the ratio of (mdot*Cp)min/(mdot*Cp)max where the heat exchanger contains two fluids for which the mdot*Cp should be calculated for each to determine which one is greater. by doing so one can define the ability of one fluid to carry thermal/heat energy with respect to the other. so this is a...
Possibly could use a wheel alignment, or tire pressure on all tires the same,or it also could be your stabilizer rods need replacing and while your looking at them check your struts and springs.good luck with that.
you will have to remove the rear seat as the pump is located behind the backrest. To remove the back seat, you need an extension for your socket wrench and remove the two nuts which are about centered where each person sits. Then lift up the seat to clear four guide/retaining clips. Having done that...
co -efficient of friction is equal to tan inverse of the inclination
Approximately 4,152,611.08 mph
The wavelength of a wave would double if the frequency was cut in half.Wavelength=c/frequency where c equals the speed of light.
Total angular momentum is always conserved - there is no way you  can violate that law. So, the answer is yes.
