Physics Questions

A galvanic cell is also known as voltaic cell provides electrical energy from the chemical energy.

Pressure = (Net Force) / (Applied area) = Newton / square meters

Measuring units of pressure are:

. Pascal
. Bar
. Torr
. Pounds per square inch (psi)
. Standard atmosphere (atm).

Any moving object can exhibit kinetic energy, as kinetic energy is also known as Motional energy.

In the given options, only a space station orbiting Earth is in motion and all the other are in rest position.

Hence, option C) a space station orbiting Earth is only exhibiting kinetic energy.

The side view mirror, in all the vehicles we use only convex mirror. This mirror makes the objects and small to show them in the mirror. That's why in all such mirrors, "Ojects in the mirror are closer than they appear."

Force of impact is the force when the objects meet. The speed of the object plays an important role in the generation of force of impact. The laws of physics determine that the force of impact increases with the square of the increase in speed.

Same charges will repel each other and the charges that are different will attract each other.
