Assume a hot system at temperature T placed in an environment at a lower temperature T0. The system emits more radiation than it absorbs and cools down whereas the surrounding absorb radiation from the systems and warm up. The system is losing power by emitting radiations at a rate.
law of successive disintegration in radioactivity
Static electricity: If electrons are removed from one material and placed on another, or if they are moved from one region of a piece of material to another, we have a separati
(i) On the average, particles are separated by a distance of the order of 10-10 m and exert a force of attraction of the order of 10-11 N on each other. (ii) The force of atta
Obtain Relativistic expression for the kinetic energy of the particle. Derive mass energy relation. Show that total energy E and momentum P are related, where m is rest mass and
A sample of argon of mass 10.4 g occupies 2100 ml at 30 o C . (i) Calculate the work done by the gas when it expands isothermally against a constant external pressure of 3
When a plane is in flight, the entire weight of the aircraft is essentially supported by the wings. To help you with this problem, it will be best if you visualize holding a model
a) Three equivalent charges 2.0 micro coulomb each, are held fixed at the three corners of an equilateral triangle of side 5 cm. Determine the Coulomb force experienced at its cent
Derive expression for total power consumed when three appliances of power p1 p2 nd p3 are connected in series.
Does weight affect how far you jump? For the same leg strength / jumping method, weight affects how far one can jump. Acceleration = Force / Mass With more mass, you can
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.
