UHS MDCAT 2019 PAPER MDCAT PAPER (PART 16) 1. If two objects of equal masses “m” are moving towards each other with the same speeds ‘v’ then what will be the total final momentum after elastic head on collision mv kg/s mv kg m/s 2 mv kg/s 0 mv kg/s 2. An automobile is moving forwards with uniform velocity due to the force exerted by its engine. If that force is double with the velocity remaining constant what happens to its total power? It is halved It is doubled It does not change It is squared 3. In Double Slit experiment, the fringe spacing of the diffracted rays increases when: The distance from mid points of the slits to the central point of the fringe on the screen increases The distance between the slits Decreases The wavelength of the diffracted rays increases The distance between the slits increases 4. The area under the extension-load graph of an elastic material whose elastic limit has not been exceeded gives its: Young modulus Strain Strain energy Stress 5. Minimum energy required to eject an electron from metal surface is called: Threshold frequency Stopping Potential Work function Electromotive force 6. The unit of magnetic flux density is the tesla, “T” it can also be expressed as 7. Percentage un-certainty in length and width of a rectangle is 2% and 3%. The total un-certainty in area of that rectangle is? 1% 6% 1.50% 5% 8. What is the quark composition of a Proton? One up quark and two strange quarks Two down quarks and one up quark Two up quarks and one strange quark Two up quarks and one down quark 9. What will be the expression for the observed frequency, if the source is moving towards the observer? 10. Molecules of a gas at constant pressure for a fixed amount of gas have average kinetic energy X. Increasing temperature from 27°C to 327°C, average K.e of molecules will become: 300X 2X 20X 200X Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
in question no 10
the type of energy reduced by the enzymes for biological reactions to occur is called ACTIVATION ENERGY
at here the correct answer is active energy which is wrong
