Answer:
<h3>5 meter / sec.</h3><h3 />
Explanation:
speed = distance / time
= 15 meters / 3 seconds
= 5 meter / sec.
In this case two vectors are colinear and they have an opposite orientation.
N + ( - S ) = N - S = 1 m - 0.8 m = 0.2 m
Answer:
The total displacement is 0.2 m north.
(2) impulse is a vector quantity. Energy has no direction, nor does power. Work is a dot product of vector quantities, which makes it a scalar.
Answer : The best pressure is 110 GPa of the lower mantle.
Explanation : We know that the pressure in the lower mantle starts at 24 GPa and reach a 136 GPa at the boundary.
So, the best pressure is 110 GPa because 220 GPa, a 305 GPa and 360 GPa are the higher value of the maximum value 136 GPa of the lower mantle.
