If you double the wavelength, the electromagnetic radiation energy will double. The energy of the electromagnetic radiation will halve if you halve the wavenumber. When the frequency of the light is doubled, its energy will.

A heavier mass m1 and a lighter mass m2 are 19.0 cm apart and experience a gravitational force of attraction that is 9.20 x 10^-9 N in magnitude. The two masses have a combined value of 5.80 kg. Determine the value of each individual mass.

The density of air under normal conditions is about 3 1.2 kg / m. For a wind speed of 10 m/s, find (a) the actual power carried in the wind; (b) the maximum power (Betz limit) extractable by a wind turbine with a blade area of 10 m2;

Do we have free will or is everything predestined?

Why does Newton's law of universal gravitation apply to all objects in the universe?

Ojectile is launched on the Earth with a certain ini - tial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one - sixth as large.
