Explanation:
As the given data is as follows.
Height, H = 150 feet
Heat gain = 30,000 BTU/hr, and Heat loss = 25000 BTU/hr
m = mass of water heated = 700 gallons = 5810 lbs
is the heat capacity of water = 1 BTU/lb 
(given)
= temperature difference = 
Heat energy required to heat 700 gal can be calculated as follows:
Heat Required = 
Thus, water rises till 
.
You need to know the energy frequency relationship for photons, which is thanks to Max Planck:
Photon Energy = Planck constant x Frequency
Rarranged:
Photon Energy / Planck Constant = Frequency
Planck Constant = 6.63x10^-34
2.93x10^-25 / 6.63x10^-34 = Frequency
Answer:
Option D. equation D
Explanation:
Positron is simply a beta plus decay or superscript 0 e subscription 1 (0 1 e).
Now, let us consider the options given:
Option A is emitting alpha decay
Option B is emitting beta minus decay.
Option C is emitting beta minus decay.
Option D is emitting beta plus decay also known as Positron.
