a gas molecule of mass10^-27 Kg is moving with a velocity of 18km h^-1 – InterviewSolution

1.

a gas molecule of mass10^-27 Kg is moving with a velocity of 18km h^-1.calculate the kinetic energy in the SI units

Answer»

Answer:

2.5×10-²⁷ J

Explanation:

KE=1/2MV²

$m = 10 {}^{ - 27} kg$

$v = 18 \times (5 \div 18) = 5 \frac{m}{s {}^{} }$

$ke = 0.5 \times 10 {}^{ - 27} \times 5 \\ = 2.5 \times 10 {}^{ - 27} j \\$
