Explanation:
Nuclear energy refers to energy trapped in the nucleus of atoms. Nuclear energy holds the greatest promise for large scale electricity generation. For instance, the amount of energy released by a given mass of uranium is 2.5 million times the energy released by combustion of an equal mass of carbon.One gram of uranium produces the same energy as 1 ton of coal, 17000 cubic feet of natural gas, 5000 pounds of wood and 149 gallons of oil.
Nuclear energy does not pollute the atmosphere as fossil fuels do. However, the challenges of effective control of the nuclear reactor and disposal of radioactive waste still remain a serious concern.
However, exploitation of nuclear energy as a source of electricity remain expensive and it is not quite easy to set up a nuclear power plant. Not many countries can afford to pay for the services of experts who operate nuclear energy plants talk more of providing the required equipment.
Answer:
b) n = 1 to n = 4.
Explanation:
a ) n = 4 to n = 1 transition represents release of energy because transition is from high energy orbit to low energy orbit.
Similarly c) n = 2 to n = 1 represents release of energy because transition is from high energy to low energy orbit.
d ) n = 1 to n = 3 is also energy absorbing transition but amount of energy absorbed is less as compared with option b) transition .
So the correct option is b)
Answer:
La ciencia y la tecnología se complementan porque la tecnología necesita que la ciencia sea una cosa y la ciencia se usa en tecnología
Explanation:
Answer:
<h2>3.00m high</h2>
Explanation:
Gravitational potential energy of the diver is expressed mathematically as
P = mgh
m = mass of the diver (in kg)
g = acceleration due to gravity (in m/s²)
h = the height of the diver above the water surface.
Given m = 85.0kg, g = 9,8m/s² and P = 2.50x10³ Joules, wecan determine how high the diver is above the water surface bu substituting the given values into the formula;
h = P/mg
h = 2.50x10³/85*9.8
h = 2500/833
h ≈ 3.00m
The diver is 3.00m above the water surface.
