An object is placed at 0 on a number line. it moves 3 units to the right, then 4 units to the left, and then 6 units to the right. the displacement of the object is

5 m right

Explanation:

Use the concept of vectors

Moves right means towards east

Moves left means towards west

d1 = 3 i

d2 = - 4i

d3 = 6 i

Net displacement, d = d1 + d2 + d3 = 3 i - 4i + 6i = 5i

Net displacement is in right with 5 m

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

we need to know the time interval during which the force acts. impulse of force = momentum change
