List some ways houses would be built differently if gravity were much stronger or weaker

Answers

Gravity plays an important role in how we build our houses and structures. If gravity was much weaker on Earth, we would be able to use structures that are not as resistant. Buildings would not have to carry as much weight, which would mean that weaker materials would be able to be used.

On the other hand, much stronger gravity would mean that buildings would have to endure a lot more pressure. Moreover, everything inside the building (furniture, people, etc.) would be heavier, which would require stronger structures.

if gravity where much weaker, then the houses wouldnt need as much structural support, and then could be built much more taller as they wouldnt go through as much stress. and if gravity was stronger, buildings would need to be alot more structurally sound and wouldnt be able to maintain a tall structure as the force of gravity would be too much for them. hope i helped :3

What is the empirical formula of sulphur dioxide which contains 50% by mass of sulphur​

Answers

Answer:

Empirical formula is SO2.

Explanation:

So the fraction of Sulphur is 0.50 and the fraction of  oxygen is 0.50.

Dividing by the atomic masses of sulphur and oxygen:

S = .50 / 32 = 0.015625

O = .50 / 16 = 0.3125

Ratio of S: O =     0.015625/ 0.015625 to 0.3125/ 0.015625    

= 1:2.

What method of forecasting uses averages to predict future weather?O
A. Persistence method
B. Climatology method
O
C. Analog method
O
D. Trends method

Answers

The climatology method of forecasting uses averages to predict future weather.

Answer: B

Explanation

The satellites and advanced technologies have helped meteorologists to forecast accurately.

There are four types of forecasting methods prevailing now.

They are climatology method, persistence method, analog method and trends method.

The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.

The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.

The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.

Climatology method is the right answer.

How does gravity affect the inner planets? (site 2)

                 

​

Answers

Answer:

Gravity is the force which helps the objects to remain in their place. In space, it helps the planets to revolve or rotate in their orbits. Gravity holds the planets together in the galaxy. It facilitates the planets to revolve around the sun. Gravity depends upon the mass of the body. The more the mass of the body, the more the gravitational force. The inner planets have less gravitational force than the outer planets. On the other hand, the Gravitational pull is stronger in the inner planets than the outer planets.

The presence of an atmosphere, temperature, and distance from the Sun do not affect a planet's gravity. Are the objects in the solar system still or are they in motion? The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them.

The elements of a heterogeneous mixture can be distinguished visually. What does this mean? a. That two separate elements have been mixed together.
b. That the components of the mixture cannot be separated.
c. That you can see the different component parts of the mixture.
d. That heterogeneous mixtures combine solids and liquids.

Answers

Answer: C. That you can see the different component parts of the mixture.

Explanation: Heterogeneous mixtures does not have a uniform apperance so the individual components of the mixture seen visually and can be separated by physical means.

The elements of a heterogeneous mixture can be distinguished visually. It means that you can see the different component parts of the mixture.

So, the correct answer is c. That you can see the different component parts of the mixture.

When a mixture is described as "heterogeneous," it means that its components are not evenly distributed, and they can be visually distinguished from each other. This is because the components exist in separate phases or regions within the mixture, and they may have different physical properties, such as color, density, size, or state of matter (solid, liquid, gas).

In a heterogeneous mixture, you can physically see or identify the different component parts without the need for specialized equipment or chemical analysis. Common examples include a salad with various ingredients, a bowl of cereal with milk, or a jar of mixed nuts.

The other options are not accurate descriptions of a heterogeneous mixture:

a. Heterogeneous mixtures can consist of more than two components, and they don't necessarily involve separate elements mixed together.

b. Heterogeneous mixtures can often be separated by physical means (e.g., filtration or hand-picking), which distinguishes them from homogeneous mixtures.

d. Heterogeneous mixtures can involve a combination of solids, liquids, or gases, but they are not limited to this combination.

Thus, the correct answer is c. That you can see the different component parts of the mixture.
