The ball has initial momentum p1= mu, and final momentum p2=vm. According to the Newton's 2nd law of motion a force exerted on the ball is equal to the rate of change of momentum . I...
As microwaves are emitted from several different sources in a confined space, the waves are reflected off the internal walls and a interference pattern is formed. There are areas of destructive superstiti...
a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.
The equation linking Power, Time, and Energy is:P=W/tAnd here P= 200 W, and t= 1800 sHence, W= 200*1800 = 360,000 JNB: Remember here, the SI units are important.
Light travels as waves which have a distinct set of properties: a speed, a frequency and a wavelength. These properties are related to each other through the following equation: speed = frequency * wavele...
