Describe the process of an action potential travelling across a synapse

An action potenial reaches the synaptic bouton causing depolarisation which opens calcium voltage gated channels. Calcium moves into the cell and causes the movement of vesicles containing acetylcholine towa...

How do you go about interpreting a poem?

The easiest way to interpret poetry is to organise it into distinct areas. These could include: poem type, rhyme, imagery, punctuation, and context. For the poem type, you would need to identify some key fea...

Expand (2x+3)^4

We will you use Pascal's triangle in order to find coefficients: 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 so, our coefficients will be 1,4,6,4,1 now, let's expand: (2x+3) 4 =(2x) 4 +4*(2x) 3 3+6 (2x) 2 3 2 +4 (2x)*3 3 ...

In a particle accelerator, you accelerate an electron. Afterwards, you measure it's energy to be 350 keV. Tell my why you can't find the speed from this energy using your knowledge of classical mechanics.

In order to see what the problem is, I will attempt to find this speed. 350keV=5.61 10 -14 J E k =1/2 * m v 2 => v=sqrt(2E k /m) By plugging in numbers, we find that the velocity of the electron, v=3.51 1...

Find the integrating factor of the following first order ODE: dx/dt = -2tx +t.

Firstly rearrange the differential equation to fit the form dx/dt +P(t)x = Q(t). The integrating factor is then found by using the formula: u = EXP(INTG(P(t))). We know that P(t) = 2t and so by integrating w...
