Two narrow slits separated by 1.0mm are illuminated by 559nm light.
Part A Find the distance between adjacent bright fringes on a screen 4.0m from the slits.
A 21 kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 80.5 N and is directed at an angle of 30° above the horizontal. Determine the coefficient of kinetic friction.
A series RCL circuit has a resonant frequency of 750 kHz, what is the value of the inductance?
A worker stands still on a roof sloped at an angle of 21° above the horizontal. He is prevented from slipping by a static frictional force of 400 N. Find out the mass of the worker.
How far does the car go before it stops. A car traveling at 50m/s runs out of gas while traveling up a 30 degree slope. how long will it travel before it rolls back down.
estimate the gravitational potential energy of the system relative to the lowest point of the motion when the cat is at its highest point.
Susie is out fishing on a calm, sunny day. She hooks an old tire that is resting on the lake bottom, and hauls it into her boat
