Light from the stars, because the orbits make it difficult to see them.
Answer:
C is the best answer because we all know that clock is part of our daily lives but we don't know the about its background
Answer:
dV/dt = 9 cubic inches per second
Explanation:
Let the height of the cylinder is h
Diameter of cylinder = height of the cylinder = h
Radius of cylinder, r = h/2
dh/dt = 3 inches /s
Volume of cylinder is given by

put r = h/2 so,

Differentiate both sides with respect to t.

Substitute the values, h = 2 inches, dh/dt = 3 inches / s

dV/dt = 9 cubic inches per second
Thus, the volume of cylinder increases by the rate of 9 cubic inches per second.
Explanation:
Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter.
Gravity affet everything and it touches nothing.
