Correct answer is A
S = \(ut + \frac{1}{2}at^2\)
S = \(0 \times 2 + \frac{1}{2} \times 30 \times 20^2\)
5500m
4500m
4200m
3000m
Correct answer is B
S = \(\frac{V^2 - U^2}{20}\)
S = \(\frac{0^2 - 30^2}{2 \times 0.1}\)

The energy of a photo having a wavelength of 10-10m is
(h= 6.63 x 10 -34Js, c =3.0 x 10 8ms-1)
2.0 x 10 -15J
1.7 x 10 -13J
2.0 x 10 -12J
1.7 x 10 -12J
Correct answer is A
E = \(\frac{hc}{\lambda}\)
E = \(\frac{6.63 \times 10^{-34} \times 3 \times 10^18}{10^{-10}}\)
E = 2 x 10-15J
