Answer:
17.Here's how electricity gets to your house:
Electricity is made at a generating station by huge generators. Generating stations can use wind, coal, natural gas, or water. The current is sent through transformers to increase the voltage to push the power long distances
18.The solar park's 7,400 panels produce enough electricity to power the equivalent of 450 homes with clean energy. ... O'Shea Solar Park generates more than electricity – it also is home to an urban pollinator garden between the rows of solar panels.

Answer:
The correct option is c. c. heat is released in the process.
Explanation:
Thermodynamics is the study of the behavior of heat energy and the ways in which energy is transformed into heat. The second law of thermodynamics indicates that from one form of energy to another (mechanical energy to chemical heat and vice versa) there is loss of energy in the form of heat. This form of energy, known as heat, is degraded energy, which is simply disorganized movement of molecules. The second law of thermodynamics implies that there is always a tendency towards greater disorder or entropy. To counteract entropy, that is to create order, energy must be used. This can be observed in a natural ecosystem: the energy emitted by the sun is captured by plants and converted into energy stored by photosynthetic processes.
Photosynthesis is the process in which the energy of light is converted into chemical energy in the form of sugars. The energy accumulated by plants during photosynthesis is called primary productivity. The solar energy that reaches the surface of an ecosystem is only used approximately 1%, because the losses are considerable until reaching primary production. In effect, approximately 45% of the available light is absorbable by photosynthetic organelles; a part of the potential radiation is reflected; another part is transmitted by the vegetal organs, that is to say, that passes through them, and the absorbed energy is transformed into heat.
As we know that;
Density= mass/volume
By rearranging
Mass=. Density* volume
Mass=. 0.2*45
Mass=. 9 grams

The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.
