Find the resistance of a fixed resistor in a circuit when the Ammeter reads 4 A and the p. d across the resistor is 12 V using Ohm’s law equation

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

Consider the phase change taking place in the picture. you could use all but one statement to describe what is happening here. that is: a) temperature is increasing. b) kinetic energy is increasing. c) the space between the particles remains the same. d) the attractive force between the particles is decreasing.

Many young black ambitious musicians migrated to harlem around 1940, where they found an alternative music scene in the after-hours that allowed them to play what they wanted to play, experiment with new harmonic concepts, and work on extending the technical mastery of their instruments.
