A horizontal rectangular sheet of length l and width w is positioned with its center a vertical distance w/2 below an infinitely long positively charged rod that has a uniform linear charge density λ.A. If the sides of length l are parallel to the rod's axis, what is the magnitude of the electric flux through the sheet?B. If the vertical distance between the sheet center and the rod is reduced to w/4does the flux magnitude increase, decrease, or stay the same?

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

a. are

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
