Correct option B
Transverse waves are those waves whose particles vibrate perpendicular to the direction of wave.

1) First of all, let's find the resistance of the wire by using Ohm's law:
where V is the potential difference applied on the wire, I the current and R the resistance. For the resistor in the problem we have:
2) Now that we have the value of the resistance, we can find the resistivity of the wire
by using the following relationship:
Where A is the cross-sectional area of the wire and L its length.
We already have its length
, while we need to calculate the area A starting from the radius:
And now we can find the resistivity:
Answer:
Explanation:
the one thrown below the horizontal is going straight down, while the one above the horizontal will experience a projectile motion which will makes it move farther away from the building where it was projected.
Answer:
I = 1.496A
Explanation:
B = (U₀ I/4πr) =3. 4 × 10⁻⁶T
3. 4 × 10⁻⁶ = 10⁻⁷ × I/0.044
I = 1.496A
