A shopper in a supermarket pushes a loaded cart with a horizontal force of 13 n. The cart has a mass of 27 kg. (a) how far will it move in 4. 0 s, starting from rest? (ignore friction. ).

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

d. air pressure decreases as altitude increases.
