An explosion occurs at an altitude of 312 m above the ground. If the air temperature is -10.00°C, how long does it take the sound to reach the ground? [velocity of sound at \(0^oC\) = 331 ms-1]
A charge of \(4.6 × 10^{-5}\)C is placed in an electric field of intensity \(3.2 × 10^4\) \(Vm^{-1}\). What is the force acting on the electron?
The branch of physics that deals with the motion of objects and the forces acting on them is called:
