Aparallel plate capacitor is connected to a battery for charging. after some time, while the battery is still connected to the capacitor, the distance between the capacitor plates is doubled.
which of the following statements are true ?
a) the charge on the plates does not change.
b) the capacitance doubles.
c) the potential difference of the battery is halved.
d) the electric field between the plates is halved.
e) the potential difference across the plates does not change.
f) none of the above.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
