Answer:
yes you are totally right
Answer: the most potential energy == 5 kg book, 2 m from the ground= 98 Joules
Explanation:
potential energy = m g h
m = mass
g = acceleration due gravity = 9.8 m/s²
h = distance above ground
1. Pe₁ = 1 kg x 2 m x g = 2 g
2. Pe₂ = 5 kg x 2 m x g = 10 g = 10 kg m x 9,8 m/s² = 98 Joules
3. Pe₃ = 1 kg x 0,5 m x g = 0,5 g
4. Pe₄ = 5 kg x 0.5 m x g = 2,5 g
10 > 2,5 > 2 >0,5
Is there a question? Because All your doing t explaining a british philosopher to us..
No,
To emit light an electron has to jump down to a lower energy level but in an electron is unable to go any lower in ground state.
The required probability is 3/4.We have to compute the probability
P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.
Determine the total number of juniors.Juniors=2+6=8
<h3>What is the probability?</h3>
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Since the number of females who are junior is 6, determine the required probability.
P(Female|Junior)=6/8=3/4
Therefore, the required probability is 3/4.
