A pendulum of Length 130.0 cm has a
period of oscillation T1 The bulb is pulled
and released to move in a horizontal circle
Of radius 50cm. If the period of rotation is T2
Calculate the ratio T1:T2

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
