Answer:
Explanation:
The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:
where,
v = root mean square velocity of molecules:
R = Universal Gas Constant
T = Equilibrium Temperature
M = Molecular Mass of the Gas
Therefore,
For T = T₁ :
For T = T₂ :
Since both speeds are given to be equal. Therefore, comparing both equations, we get:
Answer:
(a)
(b)
Explanation:
Represent losing with L and winning with W.
So:
--- Given
Probability of winning would be:
The question illustrates binomial probability and will be solved using the following binomial expansion;
So:
Solving (a): Winning at least 1
We look at the above and we list out the terms where the powers of W is at least 1; i.e., 1,2,3 and 4
So, we have:
Substitute value for W and L
<em>Hence, the probability of her winning at least one is 0.7599</em>
Solving (a): Wining exactly 2
We look at the above and we list out the terms where the powers of W is exactly 2
So, we have:
Substitute value for W and L
<em>Hence, the probability of her winning exactly two is 0.2646</em>
