A space worker exerts a net force of 256 N on an object and it accelerates at 8 m/s^2. What is the mass of the object?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

What causes the formation of ocean currents?
