PLEASE HELP! What is the magnitude of the instantaneous velocity (speed) of a freely falling object 32s after it is released from a position of rest? Consider the acceleration of gravity to be 10 m/s^2 Answer in units of m/s. What is its average speed during this 32 s interval? Answer in units of m/s. How far will it fall during this time? Answer in units of m.

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
