A block goes on a wedge which in turns goes on a horizontal table, as given in figure. The wedge angle is Φ.
As long as the wedge is in met with table, we have the trivial constraints that the vertical acceleration of the wedge is zero. To find the constraint, let x be the horizontal co-ordinate
of the end of the wedge and let y and x be the horizontal and vertical coordinate of the block as given then
(x -X) = (h - y) cot Φ
Even if the friction among the block and wedge affect their acceleration, above relation is remains as long as they are in contact.
An object is placed 25.0cm from a thin converging lens. A screen is positioned so that a sharp image of the object is seen on the screen. When the object is moved 4.0cm closer to t
a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
There are a variety of patterns that could be generates through vibrations inside a string, slinky, or rope. Every pattern corresponds to vibrations that occur at a particular freq
Force in Two and Three Dimensions - Pressure and Fluids Pressure is a force exerted over an area and is measured in Pascals (Pa). P (in Pa) = Force (in newtons) / area (
Maxwell's equations (J.C. Maxwell; 1864): Four elegant equations that describe classical electromagnetism in its entire splendor are following.
Is negative mass antimatter? No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity.
Different methods of charging a battery: There are two general methods are employed for charging are:- A) constant current system and B) constant voltage system..

Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
Q. What do you mean by Length Contraction? The length of any object in a moving frame will appear for shortened in the direction of motion. The amount of contraction can be cal
