Answer:
The most common source of energy for surface waves is wind. earthquakes. tides. volcanoes.
Explanation:
The displacement is x + (60km - 45km) - x =60km -45 km = 15 km
<span>Selection (b) is the best answer. These are the winds found between the 25-degree north and south latitudes, converging at the doldrums just north of the equator. They have been used for centuries to navigate much more quickly around the oceans.</span>
Answer:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.
The internal energy of ideal gas is U = cV The change in internal energy for ideal gas is therefore ∆U = cV ∆T, where cV is specific heat (at constant volume), and ∆T is change in tem- perature.

Answer:
-2 m/s
Explanation:
The computation of the acceleration of the block is as follows:
The volume of the block is
V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3
Now at the time of submerging in the oil
Net force is
= -2 m/s
