Answer:
The pressure exerted on the table due to the book is 200 N/m².
Explanation:
The pressure exerted on the table due to the book is 200 N/m².
The given parameters;
mass of the book, m = 400 g = 0.4 kg
dimension of the table, = 0.10m x 0.20 m.
gravitational field strength g = 10 N/kg.
The area of the table is calculated as follows;
A = 0.1 x 0.2 = 0.02 m²
The pressure exerted on the table due to the book is calculated as follows; where;
F is the force of the book due to its weight
Thus, the pressure exerted on the table due to the book is 200 N/m².

Answer:
-2 and -12
Explanation:
A dilation is a transformation of a geometric image that is known to change its size not it shape.
The size of the figure basically depends on the scale factor (k).
When k >1 then there would be expansion.
When k <1 then there would be contraction.
When k=1 then no change in size
I.e for conraction the scale factor (k) must be negative
from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12
<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>
