It is A. Number of neutrons can differ with and be the same any given element.
Answer:
the strength of the magnetic field is 3 x 10⁻⁵ T
Explanation:
Given;
velocity of the cosmic ray, v = 5 x 10⁷ m/s
force experienced by the ray, f = 1.7 x 10⁻¹⁶ N
angle between the ray's velocity and the magnetic field, θ = 45⁰
The strength of the magnetic field is calculated as;
Therefore, the strength of the magnetic field is 3 x 10⁻⁵ T
It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The one that occurs first in the generation of an action potential is that t<span>he membrane depolarizes. Hope this answers your question. Have a great day!</span>
See if you get the answer with this formulae.
<span>There are several factors that can influence sonic booms - weight, size, and shape of the aircraft or vehicle, plus its altitude, attitude and flight path, and weather or atmospheric conditions.</span>
