The diagram shows a transistor. Which explains whether boron or arsenic is the dopant
most likely used in the semiconductor layer marked
with +2
-This layer is the controller of an NPN transistor, so it
could include boron.
-This layer is the emitter of an NPN transistor, so it
could include arsenic.
-This layer is the controller of a PNP transistor, so it
could include arsenic.
-This layer is the emitter of a PNP transistor, so it
could include boron

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

Question part points submissions used suppose that 2 j of work is needed to stretch a spring from its natural length of 26 cm to a length of 36 cm. (a) how much work is needed to stretch the spring from 28 cm to 32 cm? (round your answer to two decimal places.)
