Answer:
During the voyage Charles Darwin explored the Galapagos islands and noticed the same species have different adaptations in places. ... Charles noticed that each species has the same ancestor but they evolve to adapt over time so they can live longer.
Explanation:
The equations of motion can be used to obtain the velocity as 44.7 m/s.
<h3>How are the equations of motion used?</h3>
The equations of motion are used to solve questions that bother on kinematics. In this case, we are dealing with motion under gravity. In order to find the final velocity, we have to use the equation;
v^2 = u^2 + 2gh
- v = final velocity
- u = initial velocity
- g = acceleration due to gravity
- h = height
Since he dropped from a height, u = 0 m/s
v^2 = 0^2 + 2 (10) (100)
v^2 = 2000
v = √2000
v = 44.7 m/s

The volume of the sample is 48.39 cm³.
<h3 /><h3>What is volume?</h3>
The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface
To calculate the volume of the sample, we use the formula below
Formula:
- D = m/v
- v = m/D................ Equation 1
Where:
- m = Mass of the smaple
- D = Density of the sample
- v = Volume of the sample.
From the question,
Given:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.
