Answer:
Heat
Explanation:
Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released. Heat is often produced as a by-product of a chemical reaction – this is called an exothermic reaction.

The properties of mechanical waves are : ( C and D )
- The three categories of mechanical waves are transverse, longitudinal,surface waves ( C )
- Waves transport energy,but not matter ( D )
<h3>What are mechanical waves ?</h3>
Mechanical waves are a category of waves which cannot transmit energy through a vacuum, i.e. they require a medium to transmit their energy from one end to another. An example of a mechanical wave is : sound wave. Mechanical waves are grouped into transverse, longitudinal and surface waves.
Hence we can conclude that The properties of mechanical waves are : The three categories of mechanical waves are transverse, longitudinal,surface waves and Waves transport energy,but not matter

Answer: 56994 miles
Explanation:
Given : Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed with
Standard deviation : 
Let a be the distance traveled by at least 72% of the trucks.
Let X be the random variable that represents the distance traveled by a truck
Then 
The critical value corresponds to p-value 0.72 :
Also, 
Hence, 56994 miles will be traveled by at least (equal to and more than) 72% of the trucks .
Answer:
The reading in the scale is going to be the same, or if it experiences some change it would be minimum. The reason is because the truck will act as a big closed cage, therefore, when the pigeons fly, the air they move with their wings in order to keep flying, exerts the same force on the closed cage, that if they were standing on the ground.
If the truck however, allows the air flow, the weight might change, because under this scenario, the air flowing could represent less force exerted on the balance.
