The circuit below shows some of the circuitry in a small toy robot. When the circuit is on, the robot moves its arms (the motor) and blinks a light on its head (the light bulb). 9v battery
18 ohms motor
18 ohms light

A. How much current is in the circuit when these things are happening? Hint: To find the total resistance of the circuit, add the two resistances together.

This is the number of complete movements of a wave per second.

What would people living along the coast in south florida do if there was a hurricane warning? move to locations away from the water flock along coasts to watch the natural phenomenon buy instruments to predict the exact location of the hurricane measure water levels to know the exact time of the hurricane

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
