If a pendulum had a frictionless pivot and there was no air resistance, would it oscillate forever? Or would there be damping?-theoretically yes, it will oscillate forever
but lets take the gravitatio
Does the voltage that passes through accelerate them?
Thanks!-The electric field between the grid and the emitter accelerates them.
The assembly is called an electron gun for that reason.
A metal sphere of radius R is charged to a potential V.
a.)Find the electrostatic energy stored in the electric field within a concentric sphere of radius 2R
b.) Show that the electrostatic energy sto

Two positively charged particles X and Y are initially far away from each other and at rest. X begins to move towards Y with some initial velocity. The total momentum and energy of the system are p an
would going faster than the speed of light cause a sonic flash?-Sort of.
Its impossible to reach much less exceed the speed of light in a vacuum.
However, in solid materials that are transparent, l
An object is projected vertically upwards with a speed of 24.5m s^-1 near a 29.4m tall tower. calculate the time during which the object is above the tower( ?S interval between t=? and t=?)-Let the ve
We did a experiment on Hookes Law in school .
Then , we were asked to prepare a report on the experiment .

I had a question about how to apply the Doppler Effect equation, which is:
f(0) = f(s) (v+v(0))/(v+v(s))
where
f(0) is the frequency perceived by the observer
f(s) is the frequency as actually emitt

One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in
Lower wavelength photons travel more slowly than higher wavelength photons because they travel more distance oscillating up and down, rather than moving forward, per unit of time.So would it be possib
In our atmosphere, we receive the combined light of all stars, How can we measure light of a particular star or galaxy or quasars? -Your own eyes can tell one star from another because the light from

Three capacitors C1 = 1.5 µF, C2 = 9.5 µF, and C3 = 14.5 µF are connected as shown with a battery of voltage V = 18 V. (When entering units, use micro for the metric system prefix µ.)
