Magnetic field lines come from North pole and goes to south pole, as there are two north poles, they will be going from both the poles.

In short, Your Answer would be Option 4

Hope this helps!

Classics.

Resistance is equal to relation between voltage and current.

R = \frac{U}{I}

If we express current:

I = \frac{U}{R}

If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.

So the answer should be C voltage and B zero.

Hope this helps!

A low C (f = 65Hz) is sounded on a piano. If the length of the piano wire is 2.0 m and its mass density is 5.0 g/m2, determine t
LuckyWell [14K]

Answer:

Tension of the wire(T) = 169 N

Explanation:

Given:

f = 65Hz

Length of the piano wire (L) = 2 m

Mass density = 5.0 g/m² = 0.005 kg/m²

Find:

Tension of the wire(T)

Computation:

f = v / λ

65 = v / 2L

65 = v /(2)(2)

v = 260 m/s

T = v² (m/l)

T = (260)²(0.005/2)

T = 169 N

Tension of the wire(T) = 169 N

James is trying to prove Newton's 2nd law of motion. He tries to move four different objects with different masses from point A

Toy car will take the least amount of force.
this is because the toy car has a much lighter mad than the other objects meaning it will take less force to get it to move.
