It is found that the most probable speed of molecules in a gas at equilibrium temperature
kaheart [24]

Answer:

\frac{T_2}{T_1} = 1

Explanation:

The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:

v = \sqrt{\frac{3RT}{M} }

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 :

v = \sqrt{\frac{3RT_1}{M} }

For T = T₂ :

v = \sqrt{\frac{3RT_2}{M} }

Since both speeds are given to be equal. Therefore, comparing both equations, we get:

\sqrt{\frac{3RT_1}{M} }=\sqrt{\frac{3RT_2}{M} }\\\\\frac{T_2}{T_1} = 1

Leoni is participating in four drawing competitions. If the probability of her losing any
Alex17521 [72]

Answer:

(a) Probability = 0.7599

(b) Probability = 0.2646

Explanation:

Represent losing with L and winning with W.

So:

L = 0.7 --- Given

n = 4

Probability of winning would be:

W = 1 - L

W = 1 - 0.7

W = 0.3

The question illustrates binomial probability and will be solved using the following binomial expansion;

(L + W)^4 = L^4 + 4L^3W + 6L^2W^2 + 4LW^3 + W^4

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:

Probability = 4L^3W + 6L^2W^2 + 4LW^3 + W^4

Substitute value for W and L

Probability = 4 * 0.7^3*0.3 + 6*0.7^2*0.3^2 + 4*0.7*0.3^3 + 0.3^4

Probability = 0.7599

<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:

Probability = 6L^2W^2

Substitute value for W and L

Probability = 6*0.7^2*0.3^2

Probability = 0.2646

<em>Hence, the probability of her winning exactly two is 0.2646</em>
