An action potential arrives at the synapse, triggering Ca2+ channels to open. This in turn triggers vesicles holding neurotransmitter to fuse with the presynaptic membrane, releasing the neurotransmitter ...

a) Use the equation P=IV where P is power in W, I is Current in Amps and V is voltage in volts. Rearrange to give I=P/V I=1000/230 = 4.34 A b) This is a wire connected to the metal casing of an electrical...

When you add and subtract surds, the numbers inside the square root must be the same. You add/ subtract the number outside the square root. e.g. 2√5 + 7√5 = 9√5, however 2√5 + 7√3 cannot be added. when yo...
