Answer:
<em>In the case of a solar thermal panel we are trying to heat above the ambient temperature so conduction and convection will work against us by taking heat from the panel to the out- side world. ... The sun (at 6000 C surface temperature) is hotter than the solar panel so the panel will get hot due to the solar radiation.</em>

Answer:
The coefficient of friction and acceleration are 0.37 and 2.2 m/s²
Explanation:
Suppose we find the coefficient of friction and the acceleration of the 100 kg block during the time that the 60 kg block remains in contact.
Given that,
Mass of block = 60 kg
Acceleration = 2.0 m/s²
Mass = 100 kg
Horizontal force = 340 N
Let the frictional force be f.
We need to calculate the frictional force
Using balance equation
Put the value into the formula
We need to calculate the coefficient of friction
Using formula of friction force
We need to calculate the acceleration of the 100 kg block
Using formula of newton's law
Hence, The coefficient of friction and acceleration are 0.37 and 2.2 m/s²
Differences:
<u>Reflection</u> is described as the reverting back of light or sound waves in the same medium, when it falls on plane.
<u>Refraction</u> means the shift in direction of the radio waves, when it enters medium with different density.
Comparisons:
<u>Reflection and refraction</u> <em>both</em> change the direction of light and both <em>do not </em>absorb light. All light waves can be reflected and refracted.
Both <u>Reflection and Refraction</u> are phenomenon related with wave motion of sound, and electromagnetic waves, thus including light.
