What thermodynamic properties are independent of the amount of substance present
(1). The bird drops the stone from a height of 88 m above the water surface. Initially, the stone has zero vertical velocity. How long will it take the stone to reach the surface of the pond?(Assume air resistance is negligible.)
(2). If the stone in bird enters the water at 41.6 ms-1, and takes 0.6s to travel the 3 meters to the bottom of the pond, what is its average acceleration in the pond water?
(1). What is the final velocity of a bike that starts at 4 m/s and has zero acceleration act on it for 10 seconds?
(2).How far will the bike in question 1 travel in the 10-second time period?
discuss the nature of light
obtain a relation that shows how vergence changes with distance.
write a short note on sign convention for spherical refracting surface
Explain how two thin prisms can be combined to produce without dispersion deviation of the mean light. obtain an expression for the resultant deviation
A pulley weighing 1000 N is supported on a horizontal shaft of negligible weight between two bearings, A and B, 5 metres apart. The pulley is fixed at a distance of 2 m from the bearing A. The mass centre of the polley is 20 mm from the axis of the shaft. Determine the maximum pressure on the two bearings when the shaft rotates at 200 r.p.m.
Neglect the effect of deflection of the axis of the shaft.Explain Principal points and principal planes. Show that the principal planes are the planes of unit lateral magnification
An electron is to be accelerated in a uniform electric field having a strength of 2.00 × 106 V/m.
(a) What energy in keV is given to the electron if it is accelerated through 0.400 m?
(b) Over what distance would it have to be accelerated to increase its energy by 50.0 GeV?
