Asailboat moves north for a distance of 10.00 km when blown by a wind from the exact southeast with a force of 2.00 × 104 n. the sailboat travels the distance in 1.0 h. how much work was done by the wind? what was the wind’s power? your response should include all of your work and a free-body diagram.

Work done = 1.414 × 10⁸ J

Power of the wind = 3.9 × 10⁴ W

Explanation:

Work done by the wind is scalar product of force  and displacement of the sailboat.

W = F.s = F s cos θ

Here, sailboat is moving Northwards when Wind from South-East strikes it. Thus, the angle between force and displacement is θ =45°

F = 2.00×10⁴ N

s = 10.00 km = 10⁴ m

W = 2.00×10⁴ N × 10⁴ m × cos 45° = 1.414 × 10⁸ J

Power of the boat = work done per unit time

time = 1 h = 3600 s

asthenosphere and convection

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
