478 J of work must be done to compress a gas to half its initial volume at constant temperature. How much work must be done to compress the gas by a factor of 12.0, starting from its initial volume?I was thinking of using PV = W formula. Like 478 = P(V/2) 956 = PV W = P(V/12)12W/V = P 956 = (12W/V)(V)956 = 12WW = 79.66667 Jis this correct? could someone please help?

Assume that a gravitational anomaly in the solar system has shifted a field of asteroids into Earths orbit, and the field is now moving directly towards Earth. The asteroid field has a density of rho (asteroids/volume), and each asteroid has an average mass of m. The asteroid field stretches over a distance d in Earths path. Assume that the Earth moves with a velocity of v, the asteroids with u, and that be the radius of the Earth. The Earth collides with the asteroid field:Show that the slow-down v of the Earth due to the asteroid collisions is given by:
