INELASTIC COLLISION:
"The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision".
It is to be noted that momentum and total Energy are conserved in all types of collision. However K.E is conserved only in elastic collisions.
The waves which do not needs medium for their propagation are known as non- mechanical or electromagnetic waves. Examples : Light, heat (Infrared), radio waves, gamma- rays, X-r
A car is moving along a straight horizontal road at a speed of 20 meters per second. The brakes are applied and a constant force of 5000 Newtons decelerates the car to a stop in 1
formula used in thermoelectric thermometer experiment
(i)Cathode waves always travel in straight path. (ii) Cathode rays exert mechanical force on the objects they strike. (iii) Cathode rays make fluorescence. (iv)
Characteristics of Resistance in parallel: Different amount of current passing by each resistance. i.e. I = I1 + I2 + I3 + I4 ........ The potential difference across every
What is Eclipses? Sun is a luminous body while earth and moon are non-luminous bodies. Only those parts of moon on the light of sun falls is visible. Also sun is larger than, b
The spring of constant k is un-stretched when the slider of mass m pass position B as shown in the figure above. If the slider is released from the position A, Determine: (i) S
Determine the weight of a body. Principle: When a spring is fixed at one end and a force is applied to the other end the stretching of the spring is proportional to the applie
The molecular theory of magnetism was given by Weber and modified later by Ewing. According to that theory - Each molecule of a substance is a complete magnet in itself. Though,
