Answer: The correct answer is a thick wire.

Explanation:

In the given options of the problem, a car battery is needed to generate an electrical current. It forces the electrons to flow. It makes the current flow in the circuit.

Solar cell is a device which converts the solar energy into the electrical energy. It can increase the voltage and generate an electrical current.

Generator is a device which converts the mechanical energy into the electrical energy. It can increase the voltage and generate an electrical current.

A thick wire is not used to increase voltage and generate an electrical current. The thick wire has low resistance in comparison to the thin wire.

Therefore, the correct option is (B).

Answer:

(a) The electron will move towards the wire.

The direction of the magnetic fields created by the wire can be found via right-hand rule. If you point your thumb towards the direction of the current, and if you curl your fingers, the direction of your four fingers will give the direction of the magnetic field. In this case, magnetic field is around the wire, and into the page just above the wire, where the electron is located.

$\vec{F} = q\vec{v} \times \vec{B}$

According to the above formula, the direction of the force the wire applies to the electron can be found by right-hand rule.

Since the electron has a negative charge, the direction of the force is towards the wire.

(b) The proton will veer to the right.

The direction of the magnetic field is the same as the previous part. The proton has a positive charge, and coming from above. The direction of its velocity is downwards. The magnetic field above the wire is pointed into the page. Using the right-hand rule, the magnetic force on the proton is directed to the right, with respect to us.

Teens drink mostly because the people/media around them tell them its "cool" and to be liked you have to drink, or "why miss out on the fun?" "Are you scared?" They are pressured into the idea that if they want to be cool or liked, they need to drink.
I'm not in Florida, so I wouldn't know your specific laws, but I know that driving under the influence is pretty much illegal in every state, and you will have consequences if you are caught.
Hope this helps!

notka56 [123]

Explanation:

A metal such as copper is a conductor because it provides a pathway for electric charges to move easily. A material such as rubber is an insulator because it resists the flow of electric charges. A material that partially conducts electric current is a semiconductor. These materials include group 3 and group 5 elements.

Answer:

Explanation:

Hooke's law! F(spring)=-kx

There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.
