Two long parallel wires placed side-by-side on a horizontal table carry identical size currents in opposite directions. The wire

on your right carries current toward you, and the wire on your left carries current away from you. From your point of view, the magnetic field at the point exactly midway between the two wiresA) points away from you.B) is zero.C) points toward you.D) points down.E) points up.

Answer:

D) Points down

Explanation:

We can find the direction of the magnetic field produced by each of the wire by using the right hand rule:

- the thumb must correspond to the direction of the current in the wire

- the other fingers wrap around the thumb and gives the direction of the magnetic field lines

For the wire on the right, we have:

- thumb (current): towards you

- other fingers (magnetic field): at the left of the wire, they point down

For the wire on the left, we have:

- thumb (current): away from you

- other fingers (magnetic field): at the right of the wire, they point down

So, both magnetic fields point down at the point halfway between the two wires, so the net field is also pointing down.

The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _______ and the __
Virty [35]

The correct answer is: Option (D) length, speed

Explanation:

According to Faraday's Law of Induction:

ξ = Blv

Where,

ξ = Emf Induced

B = Magnetic Induction

l = Length of the conductor

v = Speed of the conductor.

As you can see that ξ (Emf/voltage induction) is directly proportional to the length and the speed of the conductor. Therefore, the correct answer will be Option (D) Length, Speed

Net force of 8.0 N acts on an 18 kg body for one minute. Determine the impulse due to the force.
boyakko [2]

Answer:

p = FΔt = 8.0 N(60 s) = 480 N•s

Explanation:

not asked for, but in that time a frictionless 18 kg mass on a horizontal surface will have change velocity by 480/18 = 26.7 m/s.

An impulse results in a change of momentum.

What force is required to accelerate a 385 kg couch at 0.2 m/s^2 ?
Juliette [100K]

Answer:

It takes 77 N

Explanation:

Using Newton's second law of motion, F=ma (Force equals mass times acceleration. Since the mass of the couch is 385 kg and the target acceleration is 0.2 m/s, you simply multiply mass times acceleration (ma) to get the total force, or 77 N.
