A book is sitting on a desk. What best describes the normal force acting on the book?
Sladkaya [172]
My best guess would be:

"A force equal in magnitude but opposite in direction"

However I assume that this question is multiple choice, by the way it is introduced. Therefore it would be helpful if these options were also displayed - hence take this as my best guess only.

The area of a circular trampoline is 108.94 square feet. What is the radius of the trampoline? Round to the nearest hundredth.
djverab [1.8K]
The correct answer to this question is this one: B. 5.89 feet
<span>The area of a circular trampoline is 108.94 square feet. The radius of the trampoline is 5.89 feet.
</span>
For a circle,
A = (pi)r^2
108.94 ft^2 = (pi)r^2
r^2 = (108.94 ft^2)/(pi)
r = sqrt(108.94/pi) ft
r = 5. 89 ft
