A mass at the end of a spring is at distance x = +2.18 cm from the equilibrium position moving with velocity v = - 20.2 cm/s. The angular frequency of the oscillations is ? = 2.45 rad/s.
Find the amplitude of the motion in cm.
A horizontal magnetic field of 1.0x10^(-4) T is at an angle of 30 degrees to the direction of the current in a straight wire 75 cm long, what is the magnitude of the force on the wires
A source emits sound uniformly in all directions. There are no reflections of the sound. At the distance r1 from the source the sound is 3.9 dB louder than it is at a distance r2 from the source. What is the ratio r1/r2.
An object, which is initially at rest on a frictionless horizontal surface, is acted upon by four constant forces. How much total work is done on the object in 4.44 seconds
On another planet the simple pendulum consisting of a 0.154 kg mass suspended on a 1.20 m long string has a period of 3.860 seconds. What is acceleration on this planet.
