Awheel with radius 0.0600 m rotates about a horizontal frictionless axle at its center. the moment of inertia of the wheel about the axle is 2.50 kg⋅m2. the wheel is initially at rest. then at t=0 a force f(t)=(4.50n/s)t is applied tangentially to the wheel and the wheel starts to rotate.

what is the magnitude of the force at the instant when the wheel has turned through 8.00 revolutions?

Astudent creates a model of a closed ecosystem by filling a glass tank half full with water, then adding 10 snails and two small aquatic plants. the next day, all the snails are dead. what is the most likely cause of their death?

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
