KE = 0.5mV^2 = 0.5 * 0.0025 * (20)^2 =
<span>0.5 Joules.</span>
<span>Of the following gasses, CH4 will have the greatest rate of effusion at a given temperature.</span>
Answer:
<em>0.25</em>
Explanation:
According to newtons law of motion
\sum F_x = ma
F_f = ma
nR = ma
nmg = ma
ng = a
n = a/g
g is the acceleration due to gravity
Given
a = 2.42m/s²
g = 9.8m/s²
Substitute into the formula;
n = 2.42/9.8
n = 0.25
<em>Hence the coefficient of kinetic friction is 0.25</em>
