Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. what is the voltage across an 8.47-nm-thick membrane if the electric field strength across it is 8.76 mv/m? you may assume a uniform e-field.

Voltage, V = 0.0741 volts

Explanation:

It is given that,

Width of membrane,

Electric field strength,

We need to find the voltage across membrane. Electric field is given by :

V = 0.0741 V

So, the voltage across the membrane is 0.0741 volts. Hence, this is the required solution.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
