Answer:
Heating water to produce steam which drives a turbine
Explanation:
Generation of electricity in coal-burning power plants and nuclear power plants both involve heating water to produce steam which drives a turbine.
The first notion of the number of molecules per atom <span>was calculated by Josef Loschmidt which he endeavored to complete in 1895. In his experiment, he determined the number of molecules in one cubic centimeter of gas under STP. this is equal to approx 2.6 x 10^19 molecules. The former is called "Loschmidt's Constant" instead.</span>
The work done is 8427 J while the energy expended is 80.25 W.
<h3>What is work done?</h3>
Work done is defined as the product of the force and the distance. We know that the work done in a gravitational field is given as;
W = mgh
Total mass of the water bucket and chain = 13.9 kg + 19.3 kg = 33.2Kg
Distance covered = 25.9 m
W = 33.2Kg * 9.8 m/s^2 * 25.9 m
W = 8427 J
Recall that the work done = Energy expended
Power = Energy expended/ Time
Power = 8427 J/ 1.75 * 60 seconds
Power = 80.25 W

Deforestation because it gets rid of the nature and soon the land will be empty and dry
Answer: B. The gravitational field strength of Planet X is Wx/m.
Explanation:
Weight is a force, and as we know by the second Newton's law:
F = m*a
Force equals mass times acceleration.
Then if the weight is:
Wx, and the mass is m, we have the equation:
Wx = m*a
Where in this case, a is the gravitational field strength.
Then, isolating a in that equation we get:
Wx/m = a
Then the correct option is:
B. The gravitational field strength of Planet X is Wx/m.
