The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
The given parameters;
- s(t) = -9t² + 103t + 403
- time interval (4.499, 4.5), and (4.5, 4.501)
The average velocity of the bottle rocket over the intervals is calculated as follows;
when the interval = [<em>4.499, 4.5</em>]
when the interval = [<em>4.5, 4.501</em>]
The instantaneous velocity of the bottle rocket at time t=4.5;
Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

Answer/Explanation:
Energy is transferred from a hotter object to a cooler object. This is largely because of the collision of the molecules of a hotter body with the molecules of a cooler body ultimately leading to a transfer of energy from the hotter body to the cooler body. This now makes the temperature of the cooler body to rise.
Remember that temperature is a measure of the average kinetic energy of the molecules in a body.
Therefore, since the water is at a higher temperature, energy is transferred from the water to the hand and the temperature of the hand rises accordingly.
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

Explanation:
In Country A, the opportunity cost of one paper clip is 1/2. Option C
<h3>What is opportunity cost?</h3>
The opportunity cost refers to the alternative forgone in production. It means that it is the option that is chosen in the midst of other possibilities.
We can see from the table that in Country A, the opportunity cost of one paper clip is 1/2.

Program is considered a collection of code that can be run.
Computer coding, additionally referred to as computer programming, is a manner to inform a computer what to do. Coding is a way to inform the computer the way it need to behave overall - the precise movements it needs to take and the way to take them in an effective and efficient manner.
Specifically, coding is the procedure of creating after which giving the computer an in depth set of commands to be cautiously performed in sequential order. The set of commands are referred to as a software or the code. Computers are rather smart machines, however they depend on human beings for getting things done.
Simply put, coding is the art of how humans communicate with computers. It helps solve problems and build new tools that serve the community, such as apps and websites, and can analyze and process large datasets.
