2) If the centripetal force on an object in uniform circular motion is increased, what is the effect on (a) the frequency of rotation f (with r constant) and (b) f and r when both are free to vary

Ghee freezes from the bottom when cooled it but the water freezes from the top. state the reason.

The gravitational force between two objects is 1600N. What will be the gravitational force between the objects of the distance between them doubles?

Does decomposing water require high activation energy

Suppose larry stands with more weight on one scale than the other if one scale reads 400 N. what does the other read?

Which type of wave has a wave perpedicular to the disturbance? mechanical surface longitudinal tranverse

An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary, the tension in the cable was 7000 N {/rm N}.

What are the components of earths life support system

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.
