You can use a torque feeler that consists of a meterstick held at the 0 cm end with a weight dangling from various positions along the stick. When the stick is held horizontally, torque produced when a 1 kg object hangs fromt he 50 cm mark. How much torque is exerted when the object is hung from the 75 cm mark

Explanation:

Given:

length of the stick,

position of holding the stick that acts as a hinge,

mass of the object,

position of hanging the mass on the meter stick,

new position of hanging the mass,

Now the torque in the initial position:

where:

acceleration due to gravity

Now when the mass is at the new position:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
