A Ferris wheel with a diameter of 35 m starts from rest and achieves its maximum operational tangential speed of 2.3 m/s in a time of 15 s. what is the magnitude of the wheels angular acceleration? b. what is the magnitude of the tangential acceleration after the maximum operational speed is reached?​

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

(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?
