A particle moves along the x-axis according to the function x=7.0t 3 ,where x is in meters and tin seconds. 1.1 Calculate the average velocity for the time interval t=0s to t=3s.
1.2 Calculate the instantaneous acceleration for t=2s and t=4.00s.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

that would be because of both gravity and friction. so     c

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
