Acceleration is defined as the rate of change of velocity. Since velocity is a vector quantity (it has both magnitude and direction) defined as speed in a particular direction, any change in either spe...

We start with the following two observations about an object undergoing constant acceleration. First, its acceleration is equal to the change in its velocity over time, hence,

a=(v-u)/t.<...

Just equate the centripetal force and gravitational force acting on the ISS and find v.

P. S. Google the radius and mass of the Earth, the distance to the ISS from the ground, the mass of...

Olbers' paradox is a thought experiment that arises in cosmology* which shows that our universe does not fit the "Static Newtonian" model.
Sir Isaac Newton...

A potential divider is essentially a series circuit. The characteristics of a series circuit is such that voltage from the source (a battery for example) gets split across the resistors according to t...
