The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
the energy stored in the capacitor quadruples its original value.
the energy stored in the capacitor doubles its original value.
the energy stored in the capacitor is decreased to one-fourth of its original value.
the energy stored in the capacitor remains constant.
the energy stored in the capacitor is decreased to one-half of its original value.

The energy stored in the capacitor quadruples its original value.

Explanation:

The energy stored in a capacitor is given by the equation

where

C is the capacitance

V is the voltage across the plates

The capacitance, C, depends only on the properties of the capacitor, so it does not change when the voltage applied is changed.

Instead, in this problem the voltage applied is doubled:

V' = 2V

So the new energy stored is

so, the energy stored has quadrupled.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
