Question

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 1

Answer:

2.5×10-²⁷ J

Explanation:

KE=1/2MV²

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

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

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

Answer 2

Answer:

hey the answer is

Explanation:

ke=2.5×10 to the power -27 J.
