Answer:
16.732 N
Explanation:
Given:
q1 = 0.00047 C = 4.7 x 10^-4 C
q2 = 0.00089 C = 8.9 x 10^-4 C
d = 15 m
k = 9 x 10^9 N m^2 / C^2
To Find:
F = ?
Solution:
F = k x q1 x q2/d^2
F = 9 x 10^9 x 4.7 x 10^-4 x 8.9 x 10^-4 / 15 x 15
F = 9 x 4.7 x 8.9 x 10^9 x 10^-4 x 10^-4 / 225
F = 9 x 4.7 x 8.9 x 10^9 x 10^-8 / 225
F = 9 x 4.7 x 8.9 x 10 / 225
F = 418.3/25
F = 1673.2/100
Therefore, F = 16.732 N

Answer:
Explanation:
N=Rotor Speed in Revolution per minute(rpm)
for P=4 and N=3600, f comes out to be 120 Hz.
So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz).
The most practical situation is generator having N=3600Hz with 2 Poles.
Hope It will be helpful!!!
Answer: Fusion
Explanation:
Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.
Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.
