Doug is doing work. without knowing exactly what he is doing, which can be said about the work he is doing?
Ostrovityanka [42]

Energy is transferred.

<h3>What is Work?</h3>

Every time labour is performed, energy is transmitted, as shown by the definition of work in physics. Work is the result of the displacement's magnitude and the component of force acting in that direction.

What are 3 types of work done?

  • Positive
  • Negative
  • Zero work done.

Work is the result of force and distance, or the force exerted over a specific distance. In other words, Work = Force x Distance.

Joules are used to measure work.

1. Positive Work: Positive work is when a force moves an object in that direction. The motion of a ball descending toward the earth while it is displaced in the direction of the force of gravity is an illustration of this type of labour.

2. Negative Work: The work is said to be negative if the force and the displacement are in the opposing directions. For instance, if a ball is thrown high, its displacement will also be upwards, while the force from the earth's gravity will be downward.

3. Zero Work: When the force and displacement directions are parallel to one another, there is no work done on the item by the force.

In a certain velocity selector consisting of perpendicular electric and magnetic fields, the charged particles move toward the e
Aneli [31]

Answer:

Down.

Explanation:

In the given question, the charged particle is moving towards the east direction. Suppose east direction towards the positive x-axis.

And the magnetic field directed towards to the north direction. Suppose north direction towards the positive y-axis.

Therefore force of magnetic field can be calculate by the formula,

F=q(vi\times Bj)\\F=qvB(k)

Therefore force of the magnetic field is in positive z-axis means in an upward direction.

Now the force on the electric field must be in the opposite direction means it is in a downward direction.

Yes, the answer is in fact C. All of the above.

Variable stars are stars that change in brightness. The change could be due to the physical change in the star or it could also be caused when another star crosses another, or in other words eclipse.
