a bowling ball rolled with a force of 15N accelerates at a rate of 5 m/sec^2 a second ball rolled with the same force accelerates 4 m/sec^2. what are the mass of the two balls.

A piano tuner uses a tuner to create a tone of 5.00 x 10² Hz. When a key on the piano is struck he hears 5 beats per second. What is a possible frequency of vibration for the piano string? 2500 hz 1300 hz 605 hz 495 hz

Compare the motion of the particles when the frequency is high to the low-frequency motionHow would you describe the difference?

The force acting on an object moving with constant acceleration is given by F = ma, where m is the mass of the object measured in kg, a is the acceleration in m/s2, and F is the force acting on the object, measured in newtons.

How are the forces observed related to the motion of the earth around the sun

If there were no energy lost to friction in a pendulum, then the pendilum bob would
