Answer:
0.15 nm
Explanation:
d = Distance between the atomic planes
m = Order
= First angle = 
= Adjacent angle = 
= Wavelength = 0.07 nm
From Bragg's relation we know
So
The distance between the atomic planes is 0.15 nm.
Answer:
Answer:
4, 2, 5, 3, 1
Explanation:
The neuron remains at RMP unless stimulated. The stimulus results in opening of stimulus channels, this causes depolarization. if the extent of depolarization reaches to the level of threshold, the sodium and potassium channels begin opening but potassium channels are slow to open. Hence at first sodium goes out causing further depolarization until it reaches the peak at which the potassium channels open and the sodium channels close. This causes the potassium to rush our causing repolarization i.e. return of the membrane potential to RMP but the potassium channels are slow to close and it leads to hyperpolarization (undershoot) making the membrane potential more negative due to excessive movement of potassium outside the cell. Once the potassium channels close, the leak channels and Na K pump acts to return the potential to RMP.
Explanation:
<span> Use the Law of Cosines, where you have a triangle with included angle of 145 degrees and sides of 16 and 18. You are then solving the equation: </span>
<span>d^2 = 16^2 + 18^2 - 2(16)(18)cos(145) </span>
Resistance of the wire can be calculated using the following rule:
R = (ρ*L) / A
where:
R is the resistance
ρ is the resistivity of the material of the wire
L is the length of the wire
A is the area of the wire
From the above relation, we can deduce that:
The resistance of the wire is directly proportional to its length assuming all other factors are constant
