A train us moving with a velocity of 25 m/s and a car is moving behind it by a velocity of 8 m/s in same direction The relative velocity of train with respect to car is
Two charges are separated by 0.5 m. Now the 0.25 m distance between the two charges is reduced to half of the first distance, how would the electric force become
The two electric charges originally 8 cm apart are brought closer together, until they are 2 cm apart the force between them is now greater by a factor
The object is placed at the principle focus of a simple microscope if the focal length of the lens is 2cm what is the magnifying power of the microscope
Certain light of wavelength 600 nm is used to view an object under the microscope. If the aperture of its objective is 1.22 cm, then the limiting angle of resolution will be
The initial velocity of a body moving along a straight line in 7 m/s.It has a uniform acceleration of 4 m/s2.The distance covered by the body in the 5th second of its motion is
A lift is moving downwards at a very high constant speed. A passenger present inside the lift standing on a weighing machine would notice that his weight
The conversion of molecules of A to B follows a second order kineties. Doubling the concentration of A will inerease the rate of formation of B by a factor of
In the cyclic structure of the glucose when the position of atoms on carbon 1 is called one isomer changes to other. These isomers of glucose are called:
Hydrogen has a = 0.245 atm. dm3. mole-2and b = 0.0266 dm3. mole-1SO2gas has a = 6.170 atm. dm3mole-2and b = 0.0564 dm3mole where a and b are Van der Waal's constant
A mixture of H2, H2 and CH4has total number of 0.51 mole and total pressure of 1 atmosphere. If the mass of H2is 0.8 gram, then its partial pressure is
If a graph is plotted between temperature on x-axis and volume on Y-axis for 1 mole of gas,then we get straight line which cuts the temperature axis at
Methyl mercaptan, CH3SH, is one of the substances responsible for bad breath and is often used to impart a smell to natural gas in a pipeline. What will be formed when CH3SH is burned in an excess of air?
The Metropolitan Museum of Art will soon add a wing devoted entirely to modern art whereas before other museums exhibited modern art while the Met ignored it
