Answer:
When the different ions cross the neuron membrane due to this an action potential generated
Explanation:
When the different ions cross the neuron membrane due to this an action potential generated.
The steps for action potential
1. Depolarization .When positively charge sodium ions enters in to the nerve cell.This is also known as upswing.
2. Repolarization
3. Refractory Phase
So the answer is "When the different ions cross the neuron membrane".
Answer:
Explanation:
Given:
the displacement as the function of time:
here time is in seconds and the displacement in meters.
Now we differentiate this eq. of displacement to get the equation of velocity:
According to given the velocity is at some time:
& is the only time for (t>=0) instances when the particle will have a velocity of but in the opposite direction.
If you think of the forces acting east, 9 + 4 - 10 = 3 east (the - 10 from the 10 acting west, opposite to east)
Acceleration can be found using one of the following suvat equations:
Explanation:
The acceleration of an object is defined as the rate of change of velocity of the object:
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to t
There are several equations used to find the acceleration of an object moving in a straight line (they are usually called suvat equation). Depending on which quantities are given in the problem, you can use one of the following equations:
where
is the acceleration
is the distance covered
is the time
is the initial velocity
is the final velocity
