Answer:
s = 90 m
a = 56 m/s²
Explanation:
I will ASSUME that your equation is silly as it reduces to V = 11t which is constant, and that you mean V = 9t² + 2t
Position is the integral of differential velocities
s =
s = 3t³ + t² | from 0 to 3
s = 3(3)³ + 3² - (0) = 90 m
acceleration is the derivative of velocity
a = v' = 18t + 2
a(3) = 18(3) + 2 = 56 m/s²
1. Bacteria are also very important to some industries such as the production of cheese, yogurt, buttermilk, vinegar, and sauerkraut.
2. They are used in the preparation of antibiotics such as Streptomycin.
3. They are used in the tanning of leather and hides
4. They are used in the curing of tobacco (not a good thing, but notable at least�)
<span>5. Methane-producing bacteria are used in sewage treatment plants to convert the sludge into methane gas.</span>
They will make a avalanche if melted their are so many ways to melt them like the sun fire ext.
The 4 criteria you would use to compare energy sources are;
1. It is necessary to assess whether or not they are renewable.
2. It is necessary to be aware of the amount of energy that is provided per energy source unit.
3. You have to be aware of how risky it is to utilize different types of energy sources.
4. It is necessary to be aware of the effects that various types of energy sources have on the surrounding environment.
This is further explained below.
<h3>What are energy sources.?</h3>
Generally, A source from which energy that may be used can be collected or recovered, either directly or by means of a process of conversion or transformation
In conclusion, 1. You must decide if they are renewable or not.
2. You must be aware of the amount of energy provided per unit of energy source.
3. You must be aware of the safety of using various energy sources.
4. Need to understand how various energy sources affect the environment.
