Answer:
12
Explanation:
A solar eclipse occurs when the moon in between the sun and the earth. Since in reality, the moons orbit is inclined, this aligning doesnt occur often. But if the orbit of the moon were in the same plane as the earth orbit, and since the moon orbits the earth once a month, the three objects would align every month. This makes it 12 times in a year.
Answer:
Explanation:
It is given that,
The angle of the hill is 6.00° with respect to the horizontal. Let is the coefficient of kinetic friction between the surface of the hill and the toboggan.
A toboggan slides down a hill and has a constant velocity. On an inclined plane, force of friction will also act.
Force of friction, ...........(1)
Normal force, ............(2)
From equation (1) and (2) :
So, the coefficient of kinetic friction between the surface of the hill and the toboggan is 0.14. Hence, this is the required solution.
Answer:
5.88×10⁸ W
Explanation:
Power = change in energy / time
P = mgh / t
P = (m/t) gh
P = (1.2×10⁶ kg/s) (9.8 m/s²) (50.0 m)
P = 5.88×10⁸ W
