Answer:
Explanation:
The Coulomb force on the bee is:
where
is the charge of the bee
is the magnitude of the electric field
Substituting into the formula,
The gravitational force on the bee is
where
is the bee's mass
is the gravitational acceleration
Substituting into the formula,
So, the ratio between the two forces is

Answer:
<em>x=36.5 m</em>
Explanation:
<u>Rectangular Components of a Vector</u>
A vector can be expressed as an ordered pair (x,y) where x is the x-coordinate, and y is the y-coordinate of a rectangular system.
It can also be given as a magnitude-angle pair (r,θ) where θ is measured from the positive x-axis. It's also known as polar coordinates.
The conversion from polar to rectangular coordinates is:
We are given the vector as a magnitude r=47.3 m and at an angle θ=39.4°. The x-component of the vector is:
Using a scientific calculator to find the trigonometric function:
x=36.5 m
That depends on what you want to use them for.
As sources of light, they are somewhere around 15% - 20% efficient.
As heaters, they are somewhere around 80% - 85% efficient.
