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?
As an electron passes close to the positive nucleus of atom, the electron is moved from its path as given in diagram. This results in deceleration of the electron. The loss in powe
sensitivity of moving coil galvanometer can be increased by decreasing?
Write the mathematical expression for the refractive index in terms of A and D for a prism, explain the symbols. Mention any two factors on which lateral shift depends.
At 200.0 K, silicon has 3.79 x 10 -18 free electrons per atom. How many free electrons/cm 3 are there in silicon at this temperature?
Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
a) Explain the magnetic effects of current? b) Do the diagram to show the direction of motion of the conductor:
The velocity with which the group of waves travels is called as group velocity or the velocity with which a ray packet goes is called as group velocity
