The answer is "A magnetic field influences the motion of charged particles. The negatively-charged particles will experience a force acting against their motion, so the negatively-charged particles would slow down and stop moving."

This is because for example;

Have you ever seen a magnet? If so, you would experience the same scienario as above.

Answer:

option (c)

Explanation:

According to the Fleming's left hand rule, if we spread out thumb, fore finger and middle finger of our left hand mutually perpendicular to each other, then thumb represents the direction of force, fore finger represents the direction of magnetic field and the middle finger represents the direction of current.

According to the question, positive charge particle moves in left wards direction, i.e., current is flowing towards left, the force is acting upwards, so the direction of magnetic field is in perpendicular outwards to the plane of paper.

When a negatively charged particle moves towards left , then the direction of force is downwards.

Thus, the magnetic field influences the motion of charged particles. The negatively-charged particles will experience a force downward because positive and negative particles would experience forces in opposite directions.

The force an ideal spring exerts on an object is given by Fx = -kx, where x measures the displacement of the object from its equ

shusha [124]

Answer:

The work done by this force can be found via the following formula

$W = \int{F(x)} \, dx = \int\limits^0_{-20} {(-kx)} \, dx = \frac{-kx^2}{2}\left \{ {{x=0} \atop {x=-20}} \right. = \frac{-60*(-20)^2}{2} \\W = -12000J$

Explanation:

Alternatively, the work done by the object is equal to the elastic potantial energy done by the spring.

$U = \frac{1}{2}kx_2^2 - \frac{1}{2}kx_1^2 =0 - \frac{1}{2}60(-20)^2 = -12000J$

What ia difference between screw and inclined plane

Juliette [100K]

Answer:

An inclined plane makes work easier by breaking an upward or downward movement into smaller increments. Examples of inclined planes include slides, ramps, and hills. A screw is like an inclined plane wrapped around a cylinder. A screw turns a small rotational force into a larger forward driving force.

How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor

mario62 [17]

The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.
