The speed of a wave, c, is given by the length of the wave, λ, times the frequency (times per second a cycle passes). Since frequency has units of inverse seconds, the units will then be m/s as we expect.
Gravitational force of attraction between two objects can be calculated from the following formula:
Where m with subscript stands for mass of the object and r is the distance between them.
When we double the mass of those two objects, distance between them stays the same, while in the numerator we have:
When numerator in the second case 4 times greater than the 'original' numerator and denominator stays the same, force becomes 4 times greater.
