<h3><u>Answer;</u></h3>
a) 5.00 x 10^8 J
<h3><u>Explanation;</u></h3>
The work done to move the sailboat is calculated through the equation;
W = F x d
where F is force and d is the distance.
Substituting the known values from the given above,
W = (5.00 x 10⁴ N)(10 km)(1000 m/ 1km)
= 5.00 x 10⁸ J
Thus, the work done is <u>5.00 x 10⁸Joules</u>
Answer:
It's convection
Explanation:
As the hot place transfers heat to the liquid substance, it becomes less dense and rises to the surface given rise for cooler molecules directly above to fall and so undergoes the same circle. In the process the less dense particles are so light that it's swayed into the atmosphere. In the process drying is ensued.
Explanation:
The lithosphere is composed of the crust and a portion of the upper mantle. the athenosphere is partially molten upper mantle material that behaves plasticly & can flow.
It is harder to work on the lower layers because its gets extremely hot & sometimes it can get so hot that it melts tools used to research these layers.
