What is Newton's law of universal gravitation?
2 answers:
Newton's law of universal gravitation, introduced by Sir Issac Newton, states that an object entices every other object in the universe with a force or pressure that is straightly proportional to the product of their masses and reversely proportional to the square of the distance between them.
In simple expression it is a law declaring that any two masses stimulate each other with a force equal to a persistent of gravitation multiplied by the outcome of the two masses and divided by the square of the distance across the space separating between the two objects or regions.

Answer: W = J
Explanation: Since the potassium ion is at the outside membrane of a cell and the potential here is lower than the potential inside the cell, the transport will need work to happen.
The work to transport an ion from a lower potential side to a higher potential side is calculated by
q is charge;
ΔV is the potential difference;
Potassium ion has +1 charge, which means:
p = C
To determine work in joules, potential has to be in Volts, so:
Then, work is
To move a potassium ion from the exterior to the interior of the cell, it is required J of energy.
