A student's calculation for the work done on an object is shown.

The statement that describes the error in the work is that the distance must be converted to meters (m).

<h3>FORMULA FOR WORK:</h3>

Work can be calculated by using the following formula:

W = F × d

Where;

  • W = work done
  • F = force (N)
  • d = distance (m)

According to this question, the force is given as 140N and the distance is given as 30cm. The force is calculated as follows:

F = 140N × 30cm = 4200J

This calculation is erroneous because the unit of distance should be converted from cm to meters.

This question involves the concepts of the work done, S.I. unit, and Distance.

The statement that describes the error in the work is "The distance must be converted to meters."

<h2>Work done </h2>

Work done is defined as the product of the displacement covered by the object and the force applied on that object. The S.I. unit o work is Joule (J). Joule is obtained from the product of Newton (N) and meter (m).

Joule = Newton x meter

  • Hence, in order to get the work done in S.I. unit of Joule, the displacement used must also be in S.I. unit of meter (m).

Galina-37 [17]

Answer:

Explanation:

Usually the angle between the y axis  and x axis is 90° and we know that for furthest travel the degree angle must be 45° with the horizontal, Mo must release the ball about halfway between straight ahead and straight up

What happens to the average kinetic energy of water molecules as water freezes? It decreases as the water absorbs energy from it
Morgarella [4.7K]

Answer:the average kinetic energy is directly proportional to the temperature . When water freezes, the temperature decreases and therefore, the average kinetic energy will also decreases as well.
