Consider a beam of electrons, eachmoving with a speed 1.63 x 105m/s. For this problem you may find it easier to use SI units.(2) a) Find the de Broglie wavelength of the electrons. Now localize the electrons by constructing a wave packet of width 2.65 nm. (1) b) Draw a picture of the wave packet.(2) c) What range of valuesyou would now expectfrom a measurement of the speed of the electrons

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
