A ball starts from rest at point A and rolls down a ramp with uniform angular acceleration, taking 17.5 s to reach the bottom of the ramp. The slope of the ramp is now changed so that the ball has twi
Unstable atomic nuclei will spontaneously decompose to form nuclei with a higher stability. The decomposition process is called radioactivity. The energy and particles which are released during the de
A square loop 24.0cm on a side has a resistance of 5.20 ohms. It is initially in a 0.665 T magnetic field, with its plane perpendicular to B, but it is removed from the field in 40.0 ms. Calculate the
I have a 12V 0.14A pc fan which will be connected to a 35V power supply. Which resistor do I need to run the fan at 12V and and which resistor to run it at 7V (so its more quiet).
Thanks for any help
Like the ones in Dragonball,except, they would go from 1.5 to 8gs or so. How long could a person stand 2 gs? How many gs before you collapse?-The answer depends on orientation and amount of exposure,

Youre somewhat on the right track there, because, yes, light does gravitate. But the amount of it, in terms of intensity, that youd need to get a noticeable gravitational effect, would be truly astron
A 3.8 kg block of wood initially at rest is struck by a bullet moving at 494 m/s. The bullet exits the block of wood with a speed of 293 m/s.
