Atype of cuckoo clock keeps time by having a mass bouncing on a spring, usually something cute like a cherub in a chair. what force constant (in n/m) is needed to produce a period of 0.660 s for a 0.0100 kg mass?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

The inner planets or call terrestrial because they

The electric field inside a cell membrane is 8.0mn/c. what's the force on a singly charged ion in this field?
