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.
Can the whole charge of a body is transfer to another body
A pendulum is timed, first for 20 swings and then for 50 swings Time for 20 swings= 17.4s Time for 50 swings= 43.2s Calculate the average time per swing in each case.
A spring is held vertically downward and a current is passed through it . Then the length of the spring : A . increases B. decreases C . does not change D the spring osc
a) The molar mass of air is 28.97 kg/kmol and the universal gas constant is 8.314 kJ/(kmolK). Show by calculation that the particular gas constant of air is around 0.287 kJ/(kgK)
Relation among velocity wavelength and Frequency: Consider a wave of wavelength , frequency f and travelling with velocity v. The distance travel by the sound wave during th
Determine the Einstein relations by upward and downward transition. While the system is in equilibrium, the upward and downward transition rates should be equal. N 1 ρ(ν) B
The Schottky diodes are a semiconductor diode with a low forward voltage drop and a very fast switching action. The voltage drop at forward biases of around 1ma is in the range 0.1
Spark suppression: If we consider a circuit with a large inductance, possibly one using a magnetic relay. At the instant the switch is opened, the current through the coil is
