It is a question that leads us to know the proportion of one element to another. We have initially that the mass of the earth is of
m_E = 5.98*10^{24}kg
While the mass of the Moon is of
m_M = 7.35*10^{22}kg
The ratio between the two is given by the function
This means that the mass of the earth is 81.36 times larger than that of the Moon.
By applying the second equation of motion, the speed at which he threw the second stone is equal to 12.10 m/s.
<h3>How to determine the speed?</h3>
First of all, we would calculate the time taken by the first stone to reach a height of 49 meters by applying the second equation of motion as follows:
S = ut + ½gt²
49 = 0(t) + ½ × 9.8 × t²
49 = 4.9t²
t² = 49/4.9
t = √10
t = 3.16 seconds.
Now, we can determine the speed at which he threw the second stone:
<u>Note:</u> Time = 3.16 - 1 = 2.16 seconds.
S = ut + ½gt²
49 = u(2.16) + ½ × 9.8 × 2.16²
49 = 2.16u + 22.86
2.16u = 49 - 22.86
u = 26.14/2.16
u = 12.10 m/s.

Answer:
Explanation:
At the temperature of 1000K , hydrogen will have following degree of freedom
translational = 3
rotational = 2
vibrational = 1
Total = 6
Internal energy = 6N x 1 /2 k T where N is no of molecules
E₁ = 3 N kT
At the temperature of 1000K , helium will have following degree of freedom
translational = 3
rotational = 0
vibrational = 0
Total = 3
Internal energy = 3N x 1 /2 k T where N is no of molecules
E₂ = 3 / 2 N kT
Ratio = E₁ / E₂
= 2
Answer:
a.
Explanation:
a. Find the probability that exactly one photo detector of a pair is acceptable:
Let 
photo is accepted and the probability 
is defected.
Therefore:
#The probability of exactly one photo detector of a pair is accepted is 7/25
b.Find the probability that both photo detectors in a pair are defective,P(D1D2):
Hence, from out tree diagram,the probability that both photo detectors in a pair are defective is 6/25
