Nerve cells in your body can be electrically stimulated; a large enough change in a membrane potential triggers a nerve impulse. certain plants work the same way. a touch to mimosa pudica, the "sensitive plant," causes the leaflets to fold inward and droop. we can trigger this response electrically as well. in one experiment, investigators placed electrodes on the thick tissue at the base of a leaf. the electrodes were 3.5 mm apart. when the electrodes were connected to a 47 μf capacitor charged to 1.5 v, this stimulated a response from the plant. eventually, all the charge on the capacitor was transferred to the plant. how much charge was transferred? q=what was the approximate electric field between the electrodes? e=

1.

The relationship between capacitance, charge and voltage across a capacitor is:

where

Q is the charge

C is the capacitance

V is the voltage

In this problem,

is the capacitance

V = 1.5 V

Substituting, we find the charge on the capacitor, that is eventually transferred to the plant:

2. 428.6 V/m

The electric field between the electrodes is given by

where

V = 1.5 V is the potential difference across the electrodes

d = 3.5 mm = 0.0035 m is the distance between the electrodes

Substituting into the equation, we find

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
