Describe working of Heat engine
Heat engine is a device by which a system is made to undergo a cyclic process that results in conversion of heat to work.
* It having of a working substance-the system. Eg. a mixture of fuel vapour and air in a gasoline.
* The working substance goes by a cycle having of several processes. In some of these processes, it absorbs a total amount of heat Q1 from an external reservoir at some high temperature T1
* In some other processes of the cycle, the working substance releases a total amount of heat Q2 to an external reservoir at some lower temperature T2
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. II. The relationship between an object''s mass m,
Newtons laws Elephant and Feather - Free Fall Assume that an elephant and a feather are dropped off a extremely tall building from the similar height at the similar time. Assum
A car travels along a horizontal circular curved road that has a radius of 600 m. If the speed is uniformly increased at a rate of 2000 km>h2, determine the magnitude of the accele
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
Particles of the medium implement simple harmonic motion about their mean position in a direction perpendicular to the direction of propagation of wave motion. (i) It goes in th
Average acceleration is described as the change in velocity over a given time interval Δt. Hence, The instantaneous acceleration of given particle is the rat
Non- Linear circuit It can be described as that circuit whose parameters change with voltage or current.
Explain the Vector Addition of Velocity Of course the velocity is relative to how you indicate the position d. If you are moving in water that is itself moving, then your full
