Distance between a frog and an insect on a horizontal plane is 10m. Frog can jump with a maximum speed of `sqrt(10) m//s`. Minimum number of jumps required by the frog to catch the insect is : `g=10 m//s^2`.A. 5B. 10C. 100D. 50 |
|
Answer» Correct Answer - B For minimum number of jumps, range must be maximum. maximum range `=(u^(2))/g =((sqrt(10))^(2))/10=1` meter. Total distance to be covered =10 meter So total step =10 |

A velocity-time graph of two vehicals A & B starting from rest at the same time is given in the figure. The statements which is correct from graph. A. Acceleration of A is always greater than that of BB. Acceleration of B is always greater than that of AC. acceleration of A and B is constant.D. Cannot say |
|
Answer» Correct Answer - A At any time slope of curve A is greater than slope of curve B. So acceleration of A is always greater than that of B |

A stone of mass M is tied at the end of a string, is moving in a circle of radius R, with a constant angular velocity `omega`. The total work done on the stone, in any half circle, is:A. `piMR^(2) omega^(2)`B. `2 MR^(2) omega^(2)`C. `MR^(2) omega^(2)`D. 0 |
|
Answer» Correct Answer - D Since there is no change in kinetic energy of stone, the total work done on stone in any duration is zero. |
