A dog runs in a straight line for 50 meters in 12 seconds chasing a pheasant. The dog then freezes and points at the bird for 10 seconds. The bird flies away and the dog spends another 15 seconds trotting back to his starting point. What was the magnitude of the dogs average velocity in m/s during this encounter

the answer is b

explanation:

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

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.
