The receiver of a signal must understand the code or language being used to avoid confusion and losses.
<h3>What is a Signal?</h3>
This is usually in the form of a sound or body movement and is involved in conveying messages to people.
The receiver must understand the code or language in order to prevent confusion or loss of lives and properties.

Answer:
and 
. The missing ion would be 
.
Explanation:
In a double replacement reaction, two ionic compounds exchange their ions to produce two different ionic compounds.
In this question, the two ionic compounds are:
, and
.
In particular,
- is made up of
ions and 
ions, while - is made up of
ions and ions.
In a binary ionic compound, cations (positive ions) can only bond to anions (negative ions.)
- is a cation. In , was bounded anions. During the reaction, it bonds with anions to produce .
- is also a cation. In , was bounded to ions. During the reaction, it bonds with anions to produce .
Hence, the two products will be and .
Note that charges on the ions must balance. For example, a ion carries twice as much charge as an ion. As a result, each ion would bond with twice as many ions as would in .
Explanation:
It is given that,
The angular acceleration of the basketball, 
Time taken, t = 3 seconds
We need to find the ball’s final angular velocity if the ball starts from rest. It can be calculated using definition of angular acceleration i.e.
So, the ball's final angular velocity is 30 rad/s. Hence, this is the required solution.
Answer:
The car exerts a force on the truck which is c.) 6000 N.
Explanation:
If the truck exerts a force of 6000 N on the car then according to Newton's Third Law of Motion that every action has an equal and opposite reaction we can say that the force exerted by the car on the truck is 6000 N.
The only reason the truck is able to move the car is because of the frictional forces. That is frictional force of the trucks tires on the surface of the road and the frictional forces of the cars tire on the surface of the road, and since these forces are not equal this therefore gives rise to motion.
