How will u measure the volume of a stone |
|
Answer» Answer: One way to MEASURE the volume of any IRREGULAR object (in your case, a stone) is to submerge it completely under water and measure the change in the HEIGHT of the water LEVEL. This change in the water level (let's say it goes from 50 mL to 65 mL) indicates that the stone has a volume of 15 mL. |

(i) Force required in accelerating a 3 kg mass at 5 m/s² and a 4 kg mass at 4 m/s, will be(a) zero in both the cases(6) same in both the cases(c) greater for 3 kg mass at 5m/s2(d) greater for 4 kg mass at 4 m/s2 |
|
Answer» Answer: (d) greater for 4 kg mass at 4 m/s2 Because as we know that F = m×a and the mass of the object is 4 and the acceleration us also 4 which is equal to 16N Force. That is greater than the force of 15N of object A. |

A force of 200 N moves a body througha distance of 2 m in the direction offorce. Calculate the work done by theforce. |
Answer» Given :-Force applied on the body = 200 N Distance in the DIRECTION of force = 2 m To Find :-The work done by the force. Analysis :-Here we are given with the distance and and the force applied on the body. In order to find the work done by the force substitute the given values such that work done is equal to the force MULTIPLIED by the displacement. Solution :-We know that,
Using the FORMULA, Given that, Force (f) = 200 N Displacement (s) = 2 m Substituting their values, ⇒ w = fs ⇒ w = 200 × 2 ⇒ w = 400 J Therefore, he work done by the force is 400 J. |
