Answer:
<h2>False.</h2>
Explanation:
A fossil fuel is a fuel formed by natural processes. Fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. It cannot process to create fossil fuel again.
<h3>Further Explanation:</h3><h3 />
A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
Nonrenewable resources come from the Earth. Humans extract them in gas, liquid, or solid form and then convert them for their use, mainly related to energy. The reserves of these substances took billions of years to form, and it will take billions of years to replace the supplies used.
Answer:
10 Sig Figs
Explanation:
Just start counting at the first non zero after the decimal so in this case the nine, and count all of the numbers including zeros after that.
B, do earthworms prefer bright light or darkness!
Decreases
Explanation:
The acceleration due to gravity on a body decreases with depth.
Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.
- The acceleration due to gravity tend to pull all bodies to the center of the earth.
- As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
- But when a body approaches the center of the earth, the acceleration reduces.
- At depth, the acceleration due to body of a body begins to decrease.

Answer:
(a). 2.8 minutes.
(b). 0.4732
Explanation:
Without mincing words, let's dive straight into the solution to the question.
So, for the part (a), the expected arrival time can be calculated as given below.
The distribution falls between the ranges of 0(lower boundary) to 5.5minutes(upper boundary).
Therefore, the expected time = (0 + 5.5)÷ 2 = 2.75 minutes = 2.8 minutes(to 2 decimal places).
(b). The probability that an elevator arrives in less than 2.6 minutes can be calculated as given below;
Recall: We have that the upper boundary = 0 and the lower boundary = 5.5 minutes for the distribution. Also, the upper limit is equal to 2.6 minutes and the lower limits = 0 minutes.
Therefore, 1/ (5.5 - 0) = 1/5.5 = 0.182.
Therefore, the probability that an elevator arrives in less than 2.6 minutes = 0.182 ( 2.6 - 0).
The probability that an elevator arrives in less than 2.6 minutes = ( 0.182 × 2.6).
The probability that an elevator arrives in less than 2.6 minutes = 0.4732.
