Answer:

Conductors allow electricity to easily move through them.

Metal is an example of a conductor.

Explanation:

Conductors are materials that have free electrons, so they allow electrical currents (which are made of electrons traveling) passing through them.

Let's analyze each statement separately:

- Conductors allow electricity to easily move through them. --> TRUE: conductors allow electrical currents to pass through them.

- Glass is an example of a conductor. --> FALSE: glass is an example of insulator (insulators are materials that do not allow the flow of current)

- Metal is an example of a conductor. --> TRUE: metals are generally good conductors of electricity, since they have many free electrons.

- Conductors do not allow electricity to easily move through them. --> FALSE: it's actually the opposite, conductors allow electricity to easily move through them.

- Conductors restrict the flow of thermal energy. --> FALSE: conductors are generally also good conductors of thermal energy, so they do not restrict the flow of thermal energy.

Lady_Fox [76]

Answer:

1.909 m

Explanation:

Length of fence = 12 m

r = Radius of circle made by the provided fence

Cirumference of a circle is given by

$C=2\pi r$

The circumference of the circle will be equal to the length of the fence

$2\pi r=12$

$\\\Rightarrow r=\dfrac{12}{2\pi}$

$\\\Rightarrow r=1.909\ m$

The radius of the fence is 1.909 m

MissTica

The correct answer to this question is C - Gravity is a force. Gravity is also an example of a universal law. Well, according to Isaac Newton, anyway. According to Newton's Law of Universal Gravitation, 'every point mass attracts every single point mass by a force pointing along the line intersecting both paths.'

If resistor A, B and C are arranged in series, same current will flow in all the resistors and 2A will flow is resistor C.

<h3>What is series circuit?</h3>

This is the type of circuit arrangement in which the resistors are arranged in series order.

In this type of circuit arrangement, same current flows in every component of the circuit.

Thus, if resistor A, B and C are arranged in series, same current will flow in all the resistors and 2A will flow is resistor C.

Answer:

the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.

Explanation:

The magnetic force is given by the expression

F = q v x B

The bold are vectors, where v is the velocity and B is the magnetic field, the product is the cross product whose result is a vector perpendicular to the two vectors (v and B)

From the above, the force is perpendicular to the speed, it is a type of force that changes the direction of the speed, as in the uniform circular motion te, but does not change its modulus.

Even when the change in direction is real and is caused by a centripetal force

For there to be a change in the velocity modulus there must be a force parallel to the velocity direction, generally a force in electrical
