Answer:
q = 2.65 10⁻⁶ C
Explanation:
For this exercise we use Coulomb's law
F =
In this case they indicate that the load is of equal magnitude
q₁ = q₂ = q
the force is attractive because the signs of the charges are opposite
F = 
q = 
we calculate
q = 
q = 
Ra 7 10-12
q = 2.65 10⁻⁶ C
Diagram B .... light shines through at an angle
Answer:
Explanation:
From the question we are told that:
Sound level intensity
Generally the equation for intensity level is mathematically given by
Where
I= Intensity measured
<span> you divide the radius of the </span>wheel<span> by the radius of the </span>axle<span>.</span>
The effective acceleration or deceleration due to gravity depends on the inclined angle of the track relative to ground; the steeper the slope is the greater the effective acceleration.
