A rotating wheel requires 2. 98-s to rotate through 37. 0 revolutions. Its angular speed at the end of the 2. 98-s interval is 97. 2 rad/s. What is the constant angular acceleration of the wheel?.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

If element x has 99 protons how many electrons does it have

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
