Answer:

Explanation:
Additional information:
<em>The ball has charge </em>
<em>, and the ring has positive charge </em>
<em> distributed uniformly along its circumference. </em>
The electric field at distance
along the z-axis due to the charged ring is

Therefore, the force on the ball with charge
is


and according to Newton's second law

substituting
we get:

rearranging we get:

Now we use the approximation that
<em>(we use this approximation instead of the original </em>
<em> since </em>
<em>, our assumption still holds )</em>
and get


Now the last equation looks like a Simple Harmonic Equation

where

is the frequency of oscillation. Applying this to our equation we get:


Answer:
C. I think
Explanation:
C. permanent positive charges
Answer:
Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". ... So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).

Answer: Letter X in the diagram represent the angle of incidence
Explanation: One of the properties of wave is reflection. But before reflection can occur, there must have been a directed motion of wave particle towards a plane surface. The angle of incidence is the angle between the direction of motion of the wave particle ( for example; light) and the normal to the plane surface.
