HI!
Conventional vehicles use gasoline or diesel to power an internal combustion engine. Hybrids also
use an internal combustion engine—and can be fueled like normal
cars—but have an electric motor and battery, and can be partially or
wholly powered by electricity. Also pollute less and save the drivers money.
Good Day.

Doppler Radar gathers information about precipitation by sending out pulses of ___Radio wave___ energy
Answer: 2.49×10^-3 N/m
Explanation: The force per unit length that two wires exerts on each other is defined by the formula below
F/L = (u×i1×i2) / (2πr)
Where F/L = force per meter
u = permeability of free space = 1.256×10^-6 mkg/s^2A^2
i1 = current on first wire = 57A
i2 = current on second wire = 57 A
r = distance between both wires = 26cm = 0.26m
By substituting the parameters, we have that
Force per meter = (1.256×10^-6×57×57)/ 2×3.142 ×0.26
= 4080.744×10^-6/ 1.634
= 4.080×10^-3 / 1.634
= 2.49×10^-3 N/m
