Answer:
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
The correct answers are:
Winds from the ocean reduce the number of clouds.
Winds from the ocean are faster.

Answer:
Explanation:
If a baseball is hit into the air with a velocity of 27 m/s, we want to determine the maximum height of the ball. Using the projecile formula;
Max height H = u²/2g
u is the initial velocity of the body = 27m/s
g is the acceleration due to gravity = 9.81m/s²
H = 27²/2(9.81)
H = 729/19.62
H = 37.16m
Hence the ball went 37.16m high
Rolling friction ex. Riding a bike or skateboard
Sliding friction ex. Cartilage against your bone.
Fluid friction ex. Rowing a boat through the water.
Static friction ex. Trying to push a heavy object/ furniture
Speed=Distance/Time
Distance=40m,time=5.79seconds
S=40/5.79
=6.908m/s
