9. at the amusement park, a blue bumper car crashes into a red bumper car. which of the
following statements about their momentum is accurate?
a. there is less overall momentum after the collision.
b. the momentum of the red car is destroyed as it is hit.
c. there is greater overall momentum after the collision.
d. the overall momentum stavs the same before and after the collision

A)

Explanation:

Well It makes the Most sense. The momentum of the Cars were lessened due to the hit.

B is wrong because not only did the red car crash but so did the blue so the real answer should be both.

C makes no sense at all.

D The momentum is lost after collision so it is not the same, so this is false also.

HOPE THIS HELPS! :)

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

i don't know that i agree with that but what's the question ?
