Density of cylinder is 4.82 g/cm³.
<h3>What is density of a substance?</h3>
Density is the ratio of the mass and the volume of a substance
The density of the cylinder is:
mass of cylinder = 50.12 g
volume of cylinder = πr²h
r = 1.62/2 = 0.81 cm
h = 5.04 cm
volume of cylinder = 22/7 * 0.81² * 5.04
volume of cylinder = 10.39 cm³
Density of cylinder = 50.12 g/10.39 mL
Density of cylinder = 4.82 g/cm³
In conclusion, density of a substance is the ratio of mass and volume of the substance.

Answer:
Beyond our solar system, organic molecules have been found in giant clouds of dust and gas between stars and in star-forming regions.
In our solar system, besides Earth, organic molecules have been discovered on comets, in meteorites, on Saturn's moon Titan, in the plumes of water expelled from Saturn's moon Enceladus, and on Neptune's moon Triton.
Answer:
Explanation:
The flow entering the first segment will be the same as the flow exiting the second segment, and in both cases it will be equal to the velocity multiplied by the area of the segment. If
and Flow = VxA, then you have:
(1)
You can also calculate the transversal area of each segment, because blood vessels are cylinders and you know each segment's diameter. The formula to calculate this is:

Replacing d for each segment you have:

Now, replacing these values on (1), you have:



This means that velocity in the second segment is 15.4 times the velocity in which blood entered the first segment.
Answer:
60 m
Explanation:
The boat has two separate motions:
1- A motion due north, with constant speed of 10 m/s
1- A motion due east, due to the current, at speed of 2 m/s
We know that the river is 300 m wide, so we can consider first motion 1) to find how much does it take for the boat to cross the river:

Now we can find how far downstream the boat moved by calculating the distance that the boat covered moving east during this time interval:
