An archeologist finds two pieces of animal bone. The first one (a rib) contains 200 g of carbon and registers an activity of 15 decays/sec. The second piece (a jaw) contains 100 g of carbon and registers an activity of 20 decays/sec. Required:
Do the two pieces belong to the same animal? What is their age?

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

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.
