Answer:

Explanation:
Given that
Number of particle =N
Equilibrium temperature= T
Side of cube = L
Gravitational acceleration =g
The kinetic energy of an atom given as

Where
Equilibrium temperature= T
Boltzmann constant =K
K =1.380649×10−23 J/K
Answer:
1) It expresses the rate (top speed) at which it can move with time.
2) P = 20 W
3) h = 18 km
Explanation:
1) Power is the rate of transfer of energy.
⇒ Power = 
i.e P = 
Thus a car's engine power is 44000W implies that the engine of the car can propel the car at this rate. This expresses the rate (top speed) at which it can move with time.
2) m = 400g = 0.4 kg
t = 20 s
h = 100m
g = 10 m/
P = 
= 
= 
P = 20 W
3) u = 600 m/s
g = 10 m/
From the third equation of free fall,
=
- 2gh
V is the final velocity, U is the initial velocity, h is the height.
0 =
- 2 x 10 x h
0 = 360000 - 20h
20h = 360000
h = 
= 18000
h = 18 km
The maximum height of the bullet would be 18 km.
There’s no picture and what’s the length?
Answer:
Transmission
Explanation:
It’s the passage of electromagnetic waves through a medium.
Answer:
1945.6 W
Explanation:
We are given that
Height,h=1100 m
Time,t=37.5 min=
1 min=60 s
Mass,m=65 kg
Power,P=700 W
We have to find the his total metabolic power.
Power,=
Where 
Efficiency =25%
Therefore,Power,P'=
Total metabolic power=P+P'=700+1245.6=1945.6 W
