The resistance of the cylindrical wire is 
.
Here 
is the resistance, 
is the length of the wire and 
is the area of cross section. Since the wire is cylindrical 
. Rearranging the above equation,
Here 
.
Substituting numerical values,
The length of the wire is 
Being the planet closest to the sun, Mercury must be the one
with the shortest year. That's how gravity works.
Answer: Option B. R = (1/2)gt^2
Explanation:
S = R (horizontal distance)
V^2 = 2gS
V^2 = 2gR
R = V^2 / 2g
But V = gt
R = (gt)^2 / 2g
R = (g^2 x t^2) / 2g
R = gt^2 / 2
But t^2 = 2h/g
R = ( g x 2h/g) / 2
R = h
But h = (1/2)gt^2
R = h = (1/2)gt^2
Answer: the electromagnetic spectrum
Explanation:
I’m not sure but I think this is it!
The loudness was increased by the amplifier which converted electrical energy into sound energy.
