If no frictional work is considered, then the energy of the system (the driver at all positions is conserved.
Let
position 1 = initial height of the diver (h₁), together with the initial velocity (v₁).
position 2 = final height of the diver (h₂) and the final velocity (v₂).
The initial PE = mgh₁ and the initial KE = (1/2)mv₁²
where g = acceleration due to gravity,
m = mass of the diver.
Similarly, the final PE and KE are respectively mgh₂ and (1/2)mv₂².
PE in position 1 is converted into KE due to the loss in height from position 1 to position 2.
Therefore
(KE + PE) ₁ = (KE + PE)₂
Evaluate the given answers.
A) The total mechanical energy of the system increases.
FALSE
B) Potential energy can be converted into kinetic energy but not vice versa.
TRUE
C) (KE + PE)beginning = (KE + PE) end.
TRUE
D) All of the above.
FALSE
a) 
For a gas transformation occuring at a constant pressure, the work done by the gas is given by

where
p is the gas pressure
V_f is the final volume of the gas
V_i is the initial volume
For the gas in the problem,
is the pressure
is the initial volume
is the final volume
Substituting,

b) 
The heat absorbed by the gas can be found by using the 1st law of thermodynamics:

where
is the change in internal energy of the gas
Q is the heat absorbed
W is the work done
Here we have


So we can solve the equation to find Q:

And this process is an isobaric process (=at constant pressure).

Answer:
light and sound are both trasverse waves
Explanation:
Regardless of whether solar ever truly turns into a noteworthy vitality source here in England is dubious. Up to this point, the UK solar industry had been going from solidarity to quality — in 2016, power delivered from solar power outperformed coal control out of the blue.
There is absolutely enough sunlight in the UK (we get around 60 percent of the sunlight got at the equator) to make putting resources into solar advantageous – as has been exhibited by the development of enormous scale solar tasks in Cornwall and Lincolnshire.
Be that as it may, since the legislature cut its help for the solar industry in 2015, the UK has seen an emotional fall in the rate of take off of solar PV boards. This foolhardy move has additionally activated a large number of occupation misfortunes in the solar industry.
Greenpeace is requiring the English government to desperately audit its help for the solar industry, for the atmosphere and for the effect it has had on the development of clean vitality industry occupations in the UK.
