Answer:
There will always be a shadow created by the sun shining on the moon.
When the earth is in this shadow the result is a solar eclipse,
If an observer on earth can see none of the sun then this is called a total eclipse of the sun, otherwise it will be a partial ecliplse of the sun.
Note: A solar eclipse can only occur during a "new" moon at which time the moon is not visible to an observer on earth because of the light of the sun.
They depend on both MASS and DISTANCE

A simple cell can be made by connecting two different metals in contact with an electrolyte. A number of cells can be connected in series to make a battery , which has a higher voltage than a single cell. In non-rechargeable cells, eg alkaline cells, a voltage is produced until one of the reactants is used up
Second hand:
1 rev per minute = (2π radians/minute) x (1 min/60sec) = π/30 rad/sec
Minute hand:
1 rev per hour = (2π radians/hour) x (1 hr/3600 sec) = π/1800 rad/sec
Hour hand:
1 rev per 12 hours = (2π rad/12 hr) x (1 hr/3600 sec) = π/21,600 rad/sec
As long as the clock is in good working order, and the hands are turning steadily at their normal rate, there is no angular acceleration.
