Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. (Membranes are dis

Arturiano [62]

Answer:

Voltage, V = 0.0524 volts

Explanation:

Thickness of the membrane, $d=7.95\ nm=7.95\times 10^{-9}\ m$

Electric field strength, $E=6.6\ MV/m=6.6\times 10^6\ V/m$

We need to find the voltage across it. The relationship between the voltage, electric field and the distance is given by :

$V=E\times d$

$V=6.6\times 10^6\ V/m\times 7.95\times 10^{-9}$

V = 0.0524 volts

So, the voltage across the thick membrane is 0.0524 volts. Hence, this is the required solution.

Suppose the first coil of wire illustrated in the simulation is wound around the iron core 7 times. Suppose the second coil is w

SVETLANKA909090 [29]

Answer:

Emf induced in the coli will be equal to 26 volt

Explanation:

We have given number of turns N = 13

It is given that magnetic flux changes from 2.1 Weber to 2.7 Weber in 0.3 sec

Change in flux $d\Phi =2.7-2.1=0.6Weber$

Change in time dt = 0.3 sec

We have to find the induced emf

Induced emf is equal to $e=N\frac{d\Phi }{dt}=13\times \frac{0.6}{0.3}=26volt$

So emf induced in the coil will be equal to 6 volt

How does the heat transfer (a change in temperature) that occurs through ocean currents affect the land?

vlabodo [156]

Answer:

Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth's land would be habitable.
