Answer:
4 photovoltaic cells are required to meet monthly energy consumption of the cabin.
Explanation:
Let suppose that PV generation system produces energy at constant energy, the number of photovoltaic system to meet energy consumption of the cabin is:
(1)
Where:
- Energy consumption of the PV system, in kilowatt-hours.
- Power generation of the PV cell, in kilowatts.
- Working times, in hours.
If we know that , and , then the number of photovoltai cells is:
4 photovoltaic cells are required to meet monthly energy consumption of the cabin.
Answer:
Newton’s third law of motion states that every action has an equal and opposite reaction. This indicates that forces always act in pairs. Reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel each other out.
Answer:
0.2 Hz
Explanation:
f= 1/T where f= frequency and T=period
f= 1/5 sec
=0.2 Hz
The answer is false, your welcome.
B. The charge of the oxygen atom changes
This is because the neutron does not carry any electrical charge, so the charge should be unaffected.
