A potter's wheel is a disk with mass of
18.7 kg and radius of 0.230 m. The
potter pushes the edge with an 8.09 N
force. What is the resulting angular
acceleration?
[?] rad/s?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?

First to answer will be the brainliest i need the answer asap
