According to Newton’s third law, which states that an action-reaction pair of forces are equal in magnitude, the man who weighs 40 kg will push the other man with the same force of 60 N.
Universe itself means all of space and everything in it including stars, planets, galaxies, etc.
So there is no other world exist other than this universe.
The truck has a large mass. Therefore, the static friction between the truck and the road is also very high. To move the car, one has to apply a force...
(b) Primary and secondary markets complement each other. Primary market deals with the issue of new securities. That is, through the primary market a company raises capital directly from the borrowers....
On adding soap solution, lather will be formed in the beaker containing soft water only. On adding detergent solution lather will be formed by both hard and soft water.
(a) along the velocity of the wheel
Explanation:
Perimeter of the wheel = 2π*0.20 =0.4π =1.26 m
But it moves only 0.60 m.
So the wheel slips on the road. At the point of...
The correct answer is (d) 24πr2S.
Explanation:
The surface tension S is equal to surface energy per unit area, S = U/A
→U = SA
The total area of the soap bubble =2*4πr² =8πr²
The...
(a) decreases
Explanation:
The excess pressure (w.r.t. atmospheric pressure) inside a soap bubble is given as P'-P = 4S/R, {where P'-pressure inside the bubble, P- atmospheric pressure}
It is clear that the excess...
The correct answer is (1)
Artificial selection to obtain cow yielding higher milk output will shift the peak to one direction, so this represents an example of Directional selection. In stabilizing...
(c) decrease if it is taken partially out of the liquid
(d) be in the vertically upward direction.
EXPLANATION:
The force exerted by the liquid on the solid is equal to the volume...
The correct answer is (d) 24πr2S.
Explanation:
The surface tension S is equal to surface energy per unit area, S = U/A
→U = SA
The total area of the soap bubble =2*4πr² =8πr²
