Answer:
Explanation:
Speed is the distance covered over the time taken to do so.
s = d/t = 45 m / 3 s = 15 m/s
Answer:
a = 6.4 m/s²
Explanation:
a = F/m = 900 / 140 = 6.428571... m/s²
Give me some answer choices and i will be happy to help
Answer:
C and D
Explanation:
Charge on right = +0.001 C
Charge on left = 1000 C
Charge held in between = -1C
Ratio between right and left charge:

Which shows charge on left exerts 1,000,000 times more force then charge on right
Charge on left is 1000 times greater in magnitude than charge held between and charge held between is 1000 times greater in magnitude than charge on right. So the magnitude of the force on the charge you are holding would be the same if it were +1 C instead of −1 C.
