A person sitting on the top of a tall building is dropping balls at regular intervals of one second.

(a) tallness is the dominant trait

The answer is 175/396

Total combination of balls = 212 Combination of balls with no green balls = 27 Combination of balls with no blue balls = 28 Combination of balls with no blue balls  and no green...

The correct answer is (c) vA = vB  Explanation: The ball 'A' thrown vertically upward will return back to the initial point with the same thrown speed but its direction will be downwards....

Here T = \(\sqrt{\frac{2L}{g}}\)....(A) + \(\frac{L}{V}\).......(B) ΔT = ΔA + ΔB ΔT = \(\sqrt{\frac{2}{g}}\) x \(\frac{\Delta L}{2\sqrt L}\) + \(\Delta L\over V\) ΔT = \(\sqrt{\frac{1}{2gL}}\) x ΔL + \(\Delta L\over V\) 0.01 = \(\frac{1}{\sqrt{2\times10\times20}}\) x ΔL + \(\Delta L\over 300\) 0.01 = ΔL\([\frac{1}{20}+\frac{1}{300}]\) On calculating we get  ΔL = 0.1875 \(\Delta L\over L\) x 100 = \(\frac{0.1875}{20}\) x 100...

The correct answer is (c) vA = vB  Explanation: The ball 'A' thrown vertically upward will return back to the initial point with the same thrown speed but its direction will be downwards. This return...

(a) Task 1 can not be assigned to either person 1 or 2 i.e. there are 4 options. Task 2 can be assigned to 3 or 4 So, there are only 2 options...

(a) According to the given statements, only statement 1 and 4 can both be true because there may be a situation, when all the balls are black (1) or it...

(b) According to question R = y and y = 2G ∴ R = 2G Hence, the number of red balls is double the number of green balls.

correct answer is (B) G
