From research I found that the <span>fossil fuel resources are sometimes referred to as "buried sunshine" because they make the earth warm. They are also found deep in the earth and the energy stored in them was obtained from the sun long ago, and that's because they also produce energy the same way the sun does.
Hope this is the answer you were looking for and that it helps. :)</span>
Answer:
1101.96 J
Explanation:
Potential energy at top = mgh = 24*10*5 = 1200J
Kinetic energy at bottom = 1/2*m*v² = 0.5*24*(2.8)²= 94.08 J
Loss of energy = 1200 J - 98.04 J
= 1101.96 J
Thermal energy due to friction =1101.96 J
Answer:
94.82 nm
Explanation:
We have given that wavelength 
We have to find the minimum film thickness that produces the least reflection
minimum thickness is given by 
here n is given n=1.45
so minimum thickness 
so the minimum film thickness will be 94.82 nm
Answer:
Velocity
Explanation:
The rate of change in position at a given point in time is called velocity.
