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.

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...

In Nuclear Fission, neutrons collide with radioactive atoms (eg Uranium-235) in order to split the atom into two smaller atoms and releasing energy. The more n...
