Answer:
no of revolutions = 56.62 rev
Explanation:
given data
rotates = 1560 rpm
travels distance = 18.5 meters
speed = 40.2 m/s
solution
first we convert here rev/min to rev/sec
rotates = 1560 rpm = 1560 × 0.0167 = 26.052 rev/sec
we get here no of revolutions that is
no of revolutions = spin rotate ÷ time ..........1
here time = distance ÷ speed
time = 18.5 ÷ 40.2
time = 0.4601 s
put value in equation 1 we get
no of revolutions =
no of revolutions = 56.62 rev
Energy of a random atomic and molecular is called molecules energy
Answer: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! :)
Answer: Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
