larisa86 [58]

Answer:

The correct answer is - C. Multiply 500 by 1.5.

Explanation:

Given:

Force to move a desk = 500 N

weight of desk = 300 N

displacement = 1.5 meters

work done by Tine = ?

Formula:

work done (W) = F*d

where F is the force applied on the desk and d is the displacement of the desk.

Solution:

As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =

W = F*d

= 500*1.5

= 750 J

Thus, the correct answer would be option C.

It causes an increase in pigments and fatty substances (lipids) inside the cell. This makes the cells to be inactive or to function abnormally. Aging also causes the accumulation of waste products in tissues.
