The fastest nerve signals travel at speeds that exceed 100 meters per second :)
Answer:
The magnetic field required is
Explanation:
From the question we are told that there was a change in electric field with respect to time , this change can be mathematically represented as
from the question
Now substituting this into the equation
Maxwell state mathematically that
=>
Where is the length which is mathematically represented as
And S is the the surface area which is mathematically represented as
And
i.e and the value of the speed of light is
Now substituting these into the equation
From the question we are told that the diameter
The radius would be
Substituting in to the formula for B
There are "Protons" & "Neutrons" in an atom inside the nucleus. They are very massive as compared to "Electrons" (which reside outside the nucleus).So, the sentence is correct.
In short, Your Final answer would be "True"
Hope this helps!
Answer:
θ_c = 36.87°
Explanation:
Index of refraction for index medium; n_i = 2
Index of refraction for Refractive medium; n_r = 1.2
Formula to find the critical angle is given;
n_i(sin θ_c) = n_r(sin 90)
Where θ_c is critical angle.
Thus;
2 × (sin θ_c) = 1.2 × 1
(sin θ_c) = 1.2/2
(sin θ_c) = 0.6
θ_c = sin^(-1) 0.6
θ_c = 36.87°
The answer is 0 because of the velocity “u” doesn’t A
