Solar power is renewable, which means it can be used again. However, coal is non-renewable, meaning that once it is used, it can't be used again.
Electric field strength decreases as the distance from the source increases.
<h3>
How the distance from the charge affects the magnitude of the electric field?</h3>
The strength of an electric field is inversely related to square of the distance from the source. This means that the electric field strength decreases when the distance from the source increases.
So we can conclude that Electric field strength decreases as the distance from the source increases.

Answer:
60 Ω
Explanation:
R(com) = 15 Ω
1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn
1/15 = 1/20 + 1/R2
1/R2 = 1/15 - 1/20
1/R2 = (4 - 3) / 60
1/R2 = 1/60
R2 = 60 Ω
así, la combinada de resistencia necesaria es 60 Ω
Answer:
66.02m/s
Explanation:
the equation describing the distance covered in the horizontal direction is
but the acceleration in the horizontal path is zero, hence we have
Since the horizontal distance covered is 155m at 7.6secs, we have 
Also from the vertical path, the distance covered is expressed as
since the horizontal distance covered in 7.6secs is 195m, then we have
Hence if we divide both equation 1 and 2 we arrive at
Hence if we substitute the angle into the equation 1 we have
Hence the initial velocity is 66.02m/s
