A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upwa
1 answer:
The normal force acting on the legs of the table is 175 N
The weight of the books is the force exerted by the books on the table, and it is given as:
The force exerted by the table is given as:
The parameters above imply that:
- The table and the books are stationary,
- The force exerted by both act in the same downward direction.
So, the normal force acting on the legs of the table is calculated as follows:
Substitute known values
Hence, the normal force acting on the legs of the table is 175 N

Dilation involves changing the size of a line segment
The scale factor is 2
From the question (see attachment), we have the following side lengths
So, the scale factor (k) from AB to A'B' is calculated using the following scale factor formula
This gives
Divide 2.5 by 1.25
Hence, the scale factor is 2
