Hello There!
<em>If you add together all of the forces exerted on a object and get a non zero value that is called the "NET FORCE" of the object</em>
The membrane is depolarized compared to the resting membrane potential.
Through conformational changes from closed, nonconducting states to an open, current-conducting state, membrane depolarization activates sodium channels. Na+ channels open slowly and change from an open state to a nonconducting, rapidly inactivated state as a result of delayed openings, which contribute to the declining fraction of INa induced by prolonged depolarization. Additionally, sodium channels can move swiftly from the closed state to the fast-inactivated state. When the membrane is depolarized, inactivated channels are prevented from opening.
The distribution of channels between the closed and slow-inactivated states, however, limits the number of excitable sodium channels as a function of the membrane potential since slow inactivation acts at greater negative potentials than fast inactivation.

Answer:the hare slept for 1 hr 55minutes.
Explanation: distance is changed to meters = 520m
Speed=distance/time
Speed of tortoise is 0.075m/s=520m/t
Crops multiplying t= 520/0.075 = 6933.3 seconds.
Speed for hare 16.7m/s =260m/t
ie 260m is half of the distance.
t =15.56seconds
Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.
Converting to hours = 1hr. 55minutes is the time the hare slept.
