What is the mass of an object if it took 270 J of work to move it 15 meters? Please help!

Which units can be used to measure length or distance? check all that apply. gram meter kilometer liter inch

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
