May 4, The correct representation of the variation of the frictional force , f1 exerted by the table on the block with time t is given by - f' f' A B t t 0,0 0, 0 f' f' C D t t 0, 0 0, 0 Ans.
But once the body starts the motion the kinetic friction will come and it does not change with applied force A soldier with a machine gun, falling from an airplane gets detached from his parachute. If the weight of a bullet is 49 gm, what is the weight of the man with the gun?
A planet of mass m is moving around a star of mass M and radius R in a circular orbit of radius r. The star abruplly shrinks to half its radius without any loss of mass.
What change will be there in the orbit of the planet? A The planet will escape from the star B The radius of the orbit will increase C The radius of the orbit will decrease D The radius of the orbit will not change Ans.
If radius of star is decreasing without any change in mass of star then it will not affect the force exerted by star on planet which is the required centripetal force. So radius of the orbit of planet with remain unaffected. Figure a below shows a wheat stone bridge in which P, Q, R, S are fixed resistances, G is a galvanometer and B is a battery.
For this particular case the galvanometer shows zero deflection. Now, only the positions of B and G are interchanged, as shown in figure b. A charge Q is placed at the entre. An electric heater consists of a nichrome coil and runs under V, consuming 1 kW power. Part of its coil burned out and it was reconnected after cutting off the burn portion. White light is split into a spectrum by a prism and it is seen on a screen. If we put another indentical inverted prism behind it in contact, what will be seen on the screen?
This system will behave as slab. The specific heat of the material of the two blocks increases with temperature. If sp. If the specific heat of a material using this unit is J kg1X—1 its specific heat in the S. The boiling points of 0. Q Elevation of boiling point is proportional to the no. The correct electronic configuration for the ground state of silicon atomic number 14 is - A 1s2 2s2 2p6 3s2 3p2 B 1s2 2s2 2p4 3s2 3p4 2 2 6 2 4 C 1s 2s 2p 3s 3p D 1s2 2s2 2p6 3s1 3p2 Ans.
The molar mass of CaCO3 is g. A 25 1 Sol. The atomic radii of the elements across the second period of the periodic table - A decrease due to increase in atomic number B decrease due to increase in effective nuclear charge C decrease due to increase in atomic weights D increase due to increase in effective nuclear charge Ans. The gas produced on heating MnO2 with cone. An aqueous solution of HCl has a pH of 2. Consider two sealed jars of equal volume.
One contains 2 g of hydrogen at K and the other contains 28 g of nitrogen at K. The gases in the two jars will have - A the same pressure B the same average kinetic energy C the same number of molecules D the same average molecular speed Ans. C H Sol. Which of the following is a water-borne disease? In his seminal work on genetics, Gregor Mendel described the physical traits in the pea plant as being controlled by two 'factors'.
What term is used to define these factors today? In frogs, body proportions do not change with their growth. Which of the following has the widest angle of binocular vision? The two alleles of a locus which an offspring receives from the male and female gametes are situated on A Two different homologs of the same chromosome B Two different chromosomes C Sex chromosomes D A single chromosome Ans.
Ants locate sucrose by A Using a strong sense of smell B Using a keen sense of vision C Physical contact with sucrose D Sensing the particular wave length of light emitted reflected by sucrose Ans. The interior of a cow-dung piece kept for a few days is quite warm. Read on to find out more. The steps to download the questions papers are given below:.
