<h2><em>state coulombs law in word</em></h2>
- <em>: a statement in physics: <u>the force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between </u></em><em><u>them</u></em>

A) A service winner; the opponent cannot return the serve
B) A tennis stroke made across the body with the back of the hand facing the direction of the stroke
C) Exercising to increase stamina; mostly associated with aerobic activities and cardiovascular health
D) When the ball does not land in the service box
E) Is the absolute range of movement in a joint or series of joints and muscles
F) A stroke done to the right-front of the body (for right-handers), with the racket in a normal position (palm of hand facing opponent)
G) When the service hits the net and lands in a let is played and the server gets another ball
H) A sequence of shots within a point
I) Position facing the net. Used to begin most tennis strokes
J) The way the game begins. Governed by a specific set of rules
K) A tennis stroke that creates a backspin on the ball
L) To exert force on an object using muscles
M) A tennis stroke made across the body with the back of the hand facing the direction of the stroke
(a) We can find the current flowing between the walls by using Ohm's law:
where
is the potential difference and
is the resistance. Substituting these values, we get
(b) The total charge flowing between the walls is the product between the current and the time interval:
The problem says
, so the total charge is
The current consists of Na+ ions, each of them having a charge of
. To find the number of ions flowing, we can simply divide the total charge by the charge of a single ion:
