Fossil fuels are things such as natural gas, petroleum, and coal and they are made from dead organisms containing organic molecules that release energy deep in the ground they are not renewable
Answer:
130.2dB
Explanation:
The formula for determining the intensity of a wave is expressed as
Where P is the power in watts, and A is the area of the sphere formed by the wave
Data given
Power,P=3.65*10^5W
distance,d=52.7
Hence since the distance represent the radius, we can determine the area of the sphere formed
The intensity can be computed as
we can convert to decibel
D) Kilograms is the standard unit of mass

Answer:
33.65 N
Explanation:
Force that will push them away is given from the equation;
F = Kq1•q2/r²
Where;
K is coulumbs constant = 8.99 × 10^(9) Nm²/C²
We are given;
q1 = q2 = -2 C
r = 32692 m
Thus;
F = 8.99 × 10^(9) × (-2) × (-2)/32692²
F ≈ 33.65 N
