Two horses are racing in an inertial frame of reference as shown. Horse Number 1 is galloping at a speed of 10 m/s. Horse Number 2 is moving in the same direction at a speed of 7 m/s. Connect the direction and magnitude of the vector showing the velocity of Horse Number 2 from the reference frame of Horse Number 1. Connect only one vector to one velocity. 3 m/s
7 m/s
10 m/s

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

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.
