What is the volume of a weather balloon that has 39 grams of helium with a density 0.017 g/mL?
Answers
Answer:
The answer is 235.29 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question.
density = 0.017 g/mL
mass = 4 g
We have
[tex]volume = \frac{4}{0.017} \\ = 235.2941176...[/tex]
We have the final answer as
235.29 mLHope this helps you
With circulation, the heart provides your body with:
a. oxygen
b. nutrients
C. a way to get rid of waste
d. all of the above
Answers
Explanation:
The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.
Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.
When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.
In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)
So that's why the answer includes A, B and C.

The gravitational attraction between two objects is determined by the mass of the two objects and the:
A. Distance between the objects
B. Weight of the objects
C. Diameter of the objects
D. Density of the objects
Answers
Answer:
A. Distance between the objects
Explanation:
The gravitational attraction between two objects is determined by the mass of the two objects and the distance between the two objects.
According to Newton's law of universal gravitation:
"the gravitational force of attraction between two bodies is directly proportional to the product of the their masses and inversely proportional to the square of the distance between them".
F = [tex]\frac{Gm_{1}m_{2} }{r^{2} }[/tex]
F is the gravitational attraction
G is the universal gravitation constant
m is the mass
r is the distance
We can see that the gravitational attraction depends on the mass of the bodies and the distance between them.
Nio conducts a science experiment. He puts yeast into a bottle with water and sugar, and then caps the bottle with a balloon. He returns two hours later and notices there are bubbles on the surface of the mixture in the bottle and that the balloon has inflated, but there are no other apparent changes.
What most likely happened?
a non-chemical change, because there are no indicators of chemical changes taking place
a chemical change, because the mixture changed color
a chemical change, because a gas was produced
a non-chemical change, because the changes that occurred are reversible
Answers
Answer:the answer is a chemical change, because a gas was produced
Explanation: yeast is a chemical
Answer:
The answer is C.
"Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions."

All surfaces have texture, which means it affects how things move over it. When it takes a long time for friction to slow down an object, what is most likely true about the surface the object is moving on? The surface is dry. The surface is rough. The surface is uneven. The surface is smooth.
Answers
The question is incomplete, the complete question is;
All surfaces have texture, which means it affects how things move over it. When it takes a long time for friction to slow down and object, what is MOST LIKELY true about the surface the object is moving on? (A) The surface is dry (B) The surface is rough (C) The surface is uneven (D) The surface is smooth
Answer:
(D) The surface is smooth
Explanation:
Friction exists because of relative motion between two surfaces in contact with each other. However the magnitude of friction depends on how rough or smooth the surface is.
For smooth surfaces, there is little or no resistance to motion as objects move over the surface. Hence objects take a longer time to slow down on a smooth surface due to very little friction.
On a rough surface, objects tend to slow down relatively quickly. Hence, less resistance to motion on a smooth surface makes an object to take a longer time to slow down on a smooth surface than on a rough surface.
Answer: D
Explanation: Because if the surface is smooth it causes it to be more even for it to be able to cause Friction

Answers
When creating a solution, the different particles break down and combine with each other, hence why it’s called a solution, it’s creating a new solution. You can evenly mix a mixture, but it wouldn’t create a substance. So it should be D, as that is the only one that would apply to substances.
A sealed 512 cm3 flask is full to capacity with 16 g of a substance. Determine the density of the substance.
Answers
Answer:
The answer is 0.031 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 16 g
volume = 512 cm³
We have
[tex]density = \frac{16}{512} = \frac{1}{32} \\ = 0.03125[/tex]
We have the final answer as
0.031 g/cm³Hope this helps you
