Consider the following four objects: a hoop a solid sphere a flat disk a hollow sphere Each of the objects has mass M and radius R. The axis of rotation passes through the center of each object, and is perpendicular to the plane of the hoop and the plane of the flat disk. Which object requires the smallest torque to give it the same angular acceleration

If the textbook weighs 19.6 newtons on venus, what is the strength of gravity on venus?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
