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.
There is, though, the method of effective mass or apparent mass, which can be negative. When an object is submerged in water, its apparent weight is decreased by an amount equivalent to the weight of water it displaces. For instance, if a 10-pound rock is dropped into a bucket of water and displaces one pound of water, the effective weight of the rock under water is nine pounds.
Critical angle in certain substance is 300. Calculate the polarization angle of the substance?
What is the difference between a lens and a mirror? A mirror is a reflective surface. Light passes by the glass and hits the silver backing, reflecting off of it. (The angle of
Cathode rays, discovered by Sir Willium Crooke are the stream of electrons. They may be given by using a discharge tube containing gas at a low pressure of the order of 10-2 mm of
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
A charge of 111 pC is uniformly distributed throughout the volume of an isolated sphere of diameter 40 cm. Calculate the electric field at the following distances from the centre o
Air dielectric capacitors are used mainly as laboratory standards of capacitance for measurement purposes. The insulating material used in these capacitances is fused silica and th
