Your answer is c. electrons that are available for bonding.
Answer:

Explanation:
The ball is moving in a circle, so the force is centripetal.
One formula for calculating centripetal force is:

The mass of the ball is 0.5 kilograms. The radius is 1.9 meters. The centripetal force is 85 Newtons or 85 kg*m/s².
= 85 kg*m/s²- m= 0.5 kg
- r= 1.9 m
Substitute the values into the formula.

Isolate the variable v. First, multiply both sides by 1.9 meters.



Divide both sides by 0.5 kilograms.



Take the square root of both sides of the equation.



The original measurements have 2 significant figures, so our answer must have the same.
For the number we found, 2 sig fig is the ones place. The 9 in the tenth place tells us to round the 7 to an 8.

The maximum speed is approximately <u>18 meters per second.</u>
