Answer:
0.283m
Explanation:
Speed (v) = wavelength × Frequency (f)
Wavelength = speed/ frequency
Wavelength = 343/ 1210 = 0.283m
I believe the answer Air Resistance or Normal Force
The magnitude of the magnetic field in the region through the current passes is 8×10⁻³ T.
<h3>What is a magnetic field?</h3>
The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.
As we know:
F = ilB
F is the magnetic force
i is the current
l is the length
B is the magnitude of the magnetic field
Here F/l = 0.120 N/m
i = 15 A
B = (F/l)(1\i)
B = (0.120)(1/15)
B = 0.120/15
B = 8×10⁻³ T
Thus, the magnitude of the magnetic field in the region through the current passes is 8×10⁻³ T.

Electric potential difference ( ΔV ) is the difference in electric potential between the final and the initial location. It is also called voltage.
The power law equation is:
P = I * V ( P - power, I - current and V - voltage )
Therefore: V = P / I
V = 5 W / 5 A
V = 1 V.
Answer: The potential difference across a resistor is 1 V.
