The kinetic energies of a light and a heavy body are equivalent. The momentum is greater for the light body.
<h3>What is momentum?</h3>
Momentum is characterized as the intensity of a body's motion. As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity.
As a result of its higher mass, a heavy object will move with more momentum. Only when the average speed of the heavy particles is lower than that of the light particles will the average kinetic energy of the light particles equal the average kinetic energy of the heavy particles.
At the same temperature and pressure, lighter gases will move more quickly than heavier ones. 0K on the Kelvin scale denotes that the particles are not moving.

Answer:
W = 53.6648 J
Explanation:
W = ∫ F * dr
F = < 4*x i , 3*y j > Newtons
dr = < dx, 0 >
Take the dot product:
F * dr = 4* x * dx
Now replacing numeric
W = ∫ 4 * x * dx , ║ x = ( 0 m ⇒ 5.18 m )
W = ¹ / ₂ * (4 N/m) * x ²
W = (2 N/m) * (5.18 m)²
W = 53.6648 J
Rain that tends to fall in bands on earth is usually caused by : Warm, moist air rising and cooling
First, the water on earth evaporate due to sun's heat and formed cloud. Later on, this water condensed and fall again on the earth. Completing the water cycle

Answer:
209.68 years
Explanation:
Let T be the half life.
t = 1 year
N = 99.67 % of No = 0.9967 No
Use the law of radioactivity
N = No x e ^(- λ t)
Where, λ is decay constant.
λ = 0.6931 / T
So,
0.9967 No = No x e^(- λ t)
0.9967 = e^(- λ t)
e^( λ t) = 1 / 0.9967 = 1.0033
λ t = 3.3 x 10^-3
(0.6931 x 1) / T = 3.3 x 10^-3
T = 209.68 years
Thus, the halflife is 209.68 years.
