Energy Conservation on an Incline
In the given case of the cart rolling down predispose and there are three external forces (the general force, the force of friction and air resistance) and one internal force (the force of gravity). The general force does not do work upon the cart since it acts within a direction perpendicular to the direction of motion. In such examples, the angle among F and d is 90 degrees and the work completed through the force is 0 Joules. The force of friction does not do work upon the cart since it acts upon the wheels of the cart and in fact does not dish up to displace either the cart or the wheels.
The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising

A 25 N box is pulled vertically upward by means of a cord.Find the acceleration of the box if the tension in the cord is 35 N.
The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :
The focal length of a concave mirror is 2 meters. An object is positioned 8 meters in front of the mirror. Where is the image of this object formed? Ans: The image of given ob
Determine and plot the ratios μtr/μ and μab/μ from 5 keV to 100 MeV for (a) air, (b) water, (c) muscle, (d) bone, and (d) lead. Use the excel data file and use lo
What do you mean by amplification factor of a triode valve
Calculates the total magnetic flux in ring
Coupling factor: If all the flux of a primary coil links with all the turns of a secondary then 100% coupling exists. Sometimes it is more convenient to use a coupling factor
Surface tension is described as the force per unit length in the plane of a liquid surface, operating at right angles on both sides of the imaginary line drawn on the surface T
