The teeth rip and grind food into small chunks. This is also the main function of the teeth and it does help in the digestion of the food we take.
Answer:
The ratio of the diameter of iron to Cu is;
Explanation:
R=(ρL)/A
- R is resistance,
- L is length,
- A is area,
- ρ is resistivity
- d is diameter
from the question the two materials have the same resistance per unit length.
for iron = for copper
This means we can equate ρ/A for both materials.
re-arranging the equation we have,
It would be B since it starts with the solar energy which is converted to electricity with the solar panels, which then creates mechanical energy for the fans blades to move and sound for the radio.
Hope that helps :)
Answer:
Friction 100 j
Explanation:
Friction causes the inequality between PE and KE
100 J
D.Power has a time component while energy does not. This is because power is the RATE at which work is performed.
