If, for an earth satellite, the specific angular momentum is 70,000 km2/s and the specific energy is 10 km2/s2, calculate the apogee and perigee altitudes.

Explain using examples, what is simple harmonic motion and why it is an important area of study in physics.

Why does gravity have a lesser than grater effect on higher altitudes?

Estimate the magnitude of the electric field due to the proton in a hydrogen atom at a distance of 5.29×10 to the power of −11 m, the expected position of the electron in the atom.
