Explanation:

i risked my grade for this an hopefully people finds this helpful

The density of a substance equals its mass divided by its volume. Talia listed the density of some common materials at 20 °C.

Material
Density (g/cm3)
gasoline
0.70
mercury
13.6
milk
1.03
water
0.998

If Talia has 10 grams of each material, which material has the greatest volume?
Show your work below.

Answers

Answer:

mercury

Explanation:

Remember that volume = mass/density.
Therefore, if you have 10 grams of a substance, divide that by its density to find its volume.

Objects that are denser than water will sink in water. Question 1 options: True False

Answers

Answer: True

For example, a very dense metal will sink to the bottom while something like wood will float on the surface. The wood is less dense compared to the water, which is why it floats. Density is the measure of how much stuff you can pack in a certain volume. The higher the density, the more stuff per volume. Think of it like packing a suitcase. If there's barely anything in there, then we can say its density is low. The more stuff crammed in the suitcase will increase the density (and therefore the weight), while keeping the volume the same.

true

Which of the following metals is most reactive?


A. aluminum

B. sodium

C. copper

D. calcium

Answers

Answer:

A. aluminum

Explanation:

Aluminium is soft, lightweight and ductile with excellent thermal and electrical conductivity. It is highly reactive, though the metal is protected by a surface layer of inert transparent oxide (Al2O3) that forms rapidly in air, providing excellent corrosion resistance.

In this image of Earth and the Moon from the Sim, what does the circle around Earth represent?

Answers

Answer: This is the orbit (of the moon around Earth).

An orbit is a circular/oval path that planets, moons, comets, etc follow with a "subject" in the middle. In this case, the circle is the orbit of the moon around Earth.

The circle around the earth represents the orbit.

What is an orbit?

It is considered to be the regular, repeating path where one object should be in space that takes around the another one. The object in the orbit known as the satellite. It could be in natural way such as earth or moon. Also, it is the circular oval path where the planets, moons could follow the subject.

Answers

Answer:

500n

Explanation:

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

a student built a fire using coal. the coal started to burn. which statement best describes the energy changes that occurred.
A. the chemical energy stored in the coal changed to thermal energy and light energy
B. the thermal energy stored in the coal changed to light energy and chemical energy.
C. the light energy and thermal energy stored in the coal changed to mechanical energy.
D. the light energy and thermal energy stored in the coal changed to chemical energy

Answers

Answer:

98% sure the answer is A, as coal, when burning, releases thermal and light energy through the fire.

Explanation:

ANSWER: B. The thermal energy stored in the coal changed to light energy and chemical energy.
.
EXPLANATION: thermal energy is already within the coal and because of the light from the fire, that's obviously light energy. And in the end, there is a chemical reaction after the coal burns to ash, and that is chemical energy! I hope this helps!☺️ Please give Brainliest!!

what energy transformation occur when propane gas is used to lift a hot air balloon?

A. Mechanical --> light --> chemical
B. Chemical ---> mechanical --> light
C. thermal --> chemical --> light
D. chemical --> thermal --> mechanical

Answers

Answer:

the answer is D. chemical, thermal, and mecanical

The energy transformation occur when propane gas is used to lift a hot air balloon is Chemical-> mechanical-> Light.

What is Propane gas role in hot air balloon?

Propane can be produced from the components of liquid which is recovered during natural gas processing. Also these components include ethane, methane, propane, and butane, as well as heavier hydrocarbons.

The molar mass of propane is C₃H₈ - (12x3) + (1x8)= 44 g/mol.The number of moles of propane present - 0.200 mol1 mol weighs - 44 gMass of propane present  - 8.8 g

The energy conversion for the propane, that is, energy transformations that occur when propane gas is used to lift the balloon will be:

The chemical propane will be burned at first.All the process in the balloon will be checked and concluded as good mechanism without any leakage.When the propane gas was fired the balloon goes up and its gets lifted with thermal energy.The thermal energy give the Light.

Thus, the process can be simplified as the Chemical energy converting to mechanical energy which later converted to thermal energy and to the Light energy.

Hence, Option B is the correct answer.

According to Archimedes' principle, when an object is placed in a fluid, the buoyant force acting on it is equal to the weight of the fluid the object displaces. Question 3 options: True False

Answers

But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the object's weight
