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.
Propagation of an Electromagnetic Wave Electromagnetic waves are waves that can travel by the vacuum of outer space. Mechanical waves, not like electromagnetic waves, need the
Luminous flux and LASER: The luminous flux of a light source is measured in the units of LUMEN (lm). Lumen (lm) is the amount of light emitted per second by uniform (point) so
Major steps for analyzing forces in uniform circular motion: Let consider one axis along the radius of circle (i.e. in direction of acceleration) and other axis perpendicular to th
For the circuit shown in Figure, find, using the superposition theorem, (a) The current flowing in and the p.d. across the resistor, (b) The current in the 8V battery and
