Object of mass 4kg moves round a circle of radius 6m with constant speed
of 12meter per seconds calculate 1 angular velocity 2 the
force towards the center and angular displacement

What is the measurement of how fast an object moves relative to a reference point?

How can you increase the strength of an electromagnet?

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
