Answer:
1 mole has 6.023× 10^23 particles
So, In 0.622 mole no of particles = 6.023× 0.622× 10^23
=3.74 × 10^23
Answer and explanation;
-The cause of convention currents in a hot spring is rainwater and melted snow is cool and denser and sinks to the bottom of the hot spring where it is heated by a shallow magma chamber. The heated water expands and is less dense and rises to the top.
Explanation;
-Convention Current is the movement of fluid caused by the differences in temperature. Transference of heat from one part of a fluid to another.
-Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
Answer:

Answer:
<h3>130N</h3>
Explanation:
according to Newtons second law;
F = ma
F = m(v-u)/t
m is the mass = 60+5 = 65kg
v is the final velocity = 0m/s
initial velocity = 8m/s
time t = 4.0s
F = 65(8)/4
F = 65*2
F = 130N
Hence he applied a force of 130N
