Correct answer is B
\(\frac{500 \times 1.5}{100.0}\) x 100%
= 75%
667W
810W
960W
15000W
Correct answer is C
power = \(\frac{\text {work done}}{time}\)
= \(\frac{800 \times 15}{12.5}\)
= 960W
greater for Q
greater for R
the same for Q and R
greater for the heavier of the two stones
Correct answer is C
Range = \(\frac{U^2sin2\theta}{g}\)
RangeQ = \(\frac{U^2sin150}{g}\)
RangeR = \(\frac{U^2sin30}{g}\)
Since, sin30o = sin150o
therefore, RQ = RR
