Can someone please answer this real quick: Who has the greater velocity, an astronaut who has just completed an orbit of the Earth or you when you have just traveled from home to school? Explain.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

How are calculation for velocity and speed different

Does heating a metal wire increase or decrease its electrical resistance? why?
