A ball of mass 0.7 kg is dropped vertically from a height of 10 m onto a concrete floor. The ball is observed to bounce a number of times before coming to rest. The coefficient of restitution for the ball hitting the floor is 0.85;
a) Recognize and state the different types of Energy that are significant in determining the outcome of this experiment.
b) What is the total mechanical energy that the system begins with?
c) What will the velocity of the ball be instantly before it strikes the ground for the first time?
d) What is the total mechanical energy of the system directly after the balls first bounce?
e) To what height will the ball rebound after the first bounce?
f) How many times will the ball bounce?
What is double refraction? Differentiate between ordinary and extra ordinary ray.
Hawking radiation (S.W. Hawking; 1973): Black holes emit radiation such as any other hot body. Virtual particle-antiparticle pairs are being formed in supposedly empty space c
Give one advantage of a scanning electron microscope over a transmission electron microscope? The SEM has become more popular than the TEM as it can make images of high resolut
If the resultant force acting on a body of constant mass is zero, the body's momentum is: a) Increasing b) Decreasing b) Always zero d) Constant Ans: If
A Surfer sits on his board waiting as waves go by to catch a ride back to shore. Assuming the waves can be modelled as a sine wave given by h (x,t) = 1.75 sin (0.03 Πx - 0.15 Πt) [
The energy possessed by a object by virtue of its motion is known as kinetic energy (KE). The KE of a moving body is similar to the amount of work that must be given to bring a
Mechanical energy E of particle, system or object is explained as the sum of kinetic energy K and potential energy U, i.e. E = K + U. It is a scalar quantity having dimensions [ML
The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17 o C. At the beginning of the compression stroke, the cylinder vol
The world is derived from the Greek world which means to squeeze or press. It is usually described as the generation of electricity as a result of mechanical pressure. "When mechan
Q. What is electrostatic shielding? i) It is the method of isolating a certain region of space from external field. ii) It is basis on the fact that electric field inside a
