if the relation W=(F+X)/y, where W & F and force and x and y are unknown,is dimensionally correct then find the dimensions of x

How long will it take a ball to fall 81 feet

I was thinking about gravity and isn't it a meters per second per second per second acceleratory force? I mean, as you get close to an object's center of mass the force of gravity gets stronger,...

A planet has ? the density of earth but 2x the radius. find the surface gravitational force on this planet. (Hint: Earth’s is 10N/Kg)

Jupiter has a mass of 1.90 x 1027 kg. the semi-major axis of its orbit is 7.78 x 1011. Th radius of the planet is 7.14 x 107 m. Io, one of jupiter's moons, orbits at a distance...
