Now, these absolute value bars may be a bit puzzling. What we have to do is take the absolute value of the number inside of the brackets. Meaning, that if the number is negative, we make it positive, and if the number is positive, then it stays positive.

3 / -3

-1

Hope this helps!! :)

A steel ball is traveling through water with a speed of x meters per second, where x is positive the drag force, F

frozen [14]

Answer:

0.032

Step-by-step explanation:

The drag force is described as the force experienced by an object due to movement through a liquid. In this case it is water. The equation used for drag force F is:

$F=0.5pu^2$

the density of water is p=1000 kg/m³. We know that F=0.5 N.

$0.5=0.5\cdot{1000}u^2$

$u=\sqrt{0.001}$

$u=0.031$

The speed is 0.032 m/s
