Answer:
1 P = 0.5
2 P = 0.3
3 P = 0.01
Explanation:
The probability formula is

Where P is the probability V is the volume while N is the number of distinguishing particles
So for N = 1 and 

= 0.5
For N = 1 and 

= 0.3
For N = 1 and 

= 0.01
Explanation:
- In chemical reactions, chemical changes occur.
- Atoms are simply rearranged and new bonds are formed.
- Chemical reactions are driven by a need for atoms to attain stability in their structure.
- In all chemical reactions, a reactant or reactants gives new product i.e new substances are formed.
- Most these reactions are not easily reversible.
- They are usually accompanied by the release of energy.

Answer:
The velocity of the Mr. miles is 17.14 m/s.
Explanation:
It is given that,
Mr. Miles zips down a water-slide starting at 15 m vertical distance up the scaffolding, h = 15 m
We need to find the velocity of the Mr. Miles at the bottom of the slide. It is a case of conservation of energy which states that the total energy of the system remains conserved. Let v is the velocity of the Mr. miles. So,

g is the acceleration due to gravity

v = 17.14 m/s
So, the velocity of the Mr. miles is 17.14 m/s. Hence, this is the required solution.
Answer:
The generator produces electrical energy at a rate of 1378125000 J per second.
Explanation:
volume of water falling each second is 1250 
height through which it falls, h is 150 m
mass of 1
of water is 1000 kg
⇒mass of 1250
of water, m = 1250×1000 = 1250000 kg
acceleration due to gravity, g = 9.8 
in falling through 150 m in each second, by Work-Energy Theorem:
Kinetic Energy(KE) gained by it = Potential Energy(PE) lost by it
⇒KE = mgh
= 1250000×9.8×150 J
= 1837500000 J
Electrical Energy =
(KE)
=
×1837500000
= <u>1378125000 J per second</u>
