Average mass of raindrop is 3 into 10 to the power minus 5 kg and the average time a velocity is 92% |
| Answer» ENERGY - k= \frac{1}{2}mv^{2} - WHEREIN m\rightarrow mass v\rightarrow velocity Kinetic Energy is always positive. Total volume of WATER in 1 m^2 area = 1 m^2 \TIMES 100 cm = 1 m^3 Total mass in 1 m^2 area = \RHO v = 10 ^3 \times 1 Kg = 10 ^3 Kg Kinetic energy = 1/2 \times 10 ^3 \times 9 ^2 = 4.05 \times 10 ^ 4 J | |
