Answer:
Charge enter a 0.100 mm length of the axon is 
Explanation:
Electric field E at a point due to a point charge is given by
where 
is the constant =
is the magnitude of point charge and 
is the distance from the point charge
Charges entering one meter of axon is 
Charges entering 0.100 mm of axon is 
substituting the value of 
in above equation, we get charge enter a 0.100 mm length of the axon is
By afforestation.
by following recycle rule
by not using fossil file in future
There are four key characteristics of the magnetic force on a moving charge.
First, Its magnitude is proportional to the magnitude of the charge.
Second, the magnitude of the force is also proportional
Third, the magnetic force depends on the particle’s
velocity.
Fourth, we find by experiment that the magnetic force
does not have the same direction as the magnetic field
but instead is always perpendicular to both
and the velocity
So, in a mathematical language this is given by:
So, this is a cross product. Therefore, applying the Right-hand rule:
The answer is:
<span>
D. to the left of its velocity.
Explaining this in other words:
"The force </span>
is directed into the plane of the paper, so this is the direction of the proton"
Answer:
2.7x10⁻⁸ N/m²
Explanation:
Since the piece of cardboard absorbs totally the light, the radiation pressure can be found using the following equation:
<u>Where:</u>
: is the radiation pressure
I: is the intensity of the light = 8.1 W/m²
c: is the speed of light = 3.00x10⁸ m/s
Hence, the radiation pressure is:
Therefore, the radiation pressure that is produced on the cardboard by the light is 2.7x10⁻⁸ N/m².
I hope it helps you!
