\large \bold {ANSWER}

Considering that the pulley is fixed, the force applied should be equal to the weight of the object - of 400N.

\large \bold {EXPLANATION}

Pulleys or pulleys are mechanical tools used to assist in the movement of objects and bodies. There are two types of pulleys: fixed and movable. While the fixed pulley changes the direction of force, the moving pulley helps to decrease the force needed to move the object or body in question.

As the statement only tells us a pulley, we must consider that it is fixed, <u>because generally when it is mobile, this information is highlighted in the question</u>.

In this way, a fixed pulley only changes the direction of the applied force. Thus, the force must have the same magnitude as the weight of the object to be moved. If the bucket weighs 400N, the force applied to the pulley must be 400N.

<u>Therefore, having a fixed pulley, the force applied must be equal to the weight of the object, and will be 400N.</u>

OF BRICK<br> (a)<br> The pushing force does not make the brick move. Explain why.
Sever21 [200]

Every force has an equal but opposite reaction, the forces are balanced out on the brick.

Weight (mg) acts downwards from the brick but the normal contact force from the table is acting upwards therefore resultant force is 0N equilibrium

You know the direction of the force is based upon the resultant force, so if you were to push the brick horizontally across the table it would travel horizontally
