Please answer this (May give brainliest) What is the formula for angular motion and how do you do this one below

To throw a curve ball, a pitcher gives the ball an initial angular speed of 36rad/s. When the catcher gloves the ball 0.6s later, its angular speed has decreased (due to air resistance) to 34rad/s. How many revolutions did the ball make before being caught?
Select one:
a. 15rad
b. 10rad
c. 25rad
d. 21rad

Aforce of 100 newtons is used to move an object a distance of 15 meters with a power of 50 watts. find the work dine and the time it takes to do the work

Heterogeneous mixture with larger particles that never settle is

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
