Three balls are used to model the Sun-Earth-Moon system. Which statement describes a benefit of this model?

Answers

Options are not given in the question, so the complete question is as follows:

Three balls are used to model the Sun-Earth-Moon system. Which statement

describes the benefit of this model?

A. The model shows only how eclipses happen.

B. It shows information about a system too large to be studied easily.

C. It shows information about a system too fast to be studied  directly

D. The model can be used for the entire solar system.

Answer:

B. It shows information about a system too large to be studied easily.

Explanation:

The use of balls in the model makes it easy to understand the large solar system.

The solar system is comprised of the sun, moon, planets, and other celestial bodies. The model using three balls makes it easy to understand a large system. Using these balls many things about the solar system can be learned such as the position of the Sun-Earth-Moon, the phenomenon of rotation and revolution, and eclipses.

So, the given models show that a large solar system can be studied easily.

Hence, the correct option is "B".

Answer:

B. It shows information about a system too large to be studied easily.

What do the planets have in common and how are they different?

Answers

They are all different sizes and distances from the sun, they all rotate around the sun

Answer:

They vary quite a lot, yet there are some similarities

Explanation:

With Mercury, you have a hot and barren expanse of rock

With Venus, you also have a fairly hot and barren expanse of rock, with a molten core

With Earth, you have a warm/cool variant with water and a full atmosphere

With Mars, you have a colder and barren expanse of valleys and rock, with a rather paste-like ground

With Jupiter, we have our first gas giant, covered in clouds with a thick atmosphere

With Saturn, it is yet another gas giant, with rings of gas and rock and a dense core of metals, such as iron and nickel

With Uranus, it is also rather gas-full with a fair amount of water and methane, which results in its bluish color (an ice giant)

And finally with Neptune, it is the other ice giant, consisting of water, methane, and ammonia

So there are some similarities (gases, water, land formations, etc.) and some differences (rings, temperature, structure, etc.). Our planets are very unique to one another and continue to engage and surprise us.

A truck covers 40.0 m in 7.10 s while uniformly slowing down to a final velocity of 2.05 m/s.
(a) Find the truck's original speed. _______ m/s
(b) Find its acceleration. __________ m/s^2

Answers

Answer:

(A) Original speed= 9.22 m/s

(B) Acceleration= -1.0099 m\s^2

Explanation:

A truck covers 40m in 7.10 secs

The truck slows down at a uniform velocity of 2.05 m/s

(A) The original speed can be calculated as follows

Vo= 2(40)/7.10 - 2.05

= 80/7.10 - 2.05

= 11.2676 - 2.05

= 9.22m/s

(B) The acceleration can be calculated as follows

a= Vf-Vo/t

= 2.05-9.22/7.10

= -7.17/7.10

= -1.0099m/s^2

an ice cube is placed in the sun later there is a puddle of water later still the.puddle is gone what kind of change has occured​

Answers

Clear question is;

An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?

Answer:

Physical change.

Explanation:

There are two type of changes called physical change and chemical change.

In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.

Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.

2. A ball is dropped from a height of 52 m. The ball falls freely and reaches the ground in 75 s. What was the average speed of the ball?​

Answers

Answer:

v = 0.69 m/s

Explanation:

Given that,

A ball is dropped from a height of 52 m.

The ball reaches the ground in 75 seconds

We need to find the average speed of the ball. The ball will travel a distance of 52 m in 75 s. The average speed of the ball is distance divided by time taken. So,

[tex]v=\dfrac{52\ m}{75\ s}\\\\v=0.69\ m/s[/tex]

Hence, the average speed of the ball is 0.69 m/s.

A competitive go-cart driver is traveling 32 m/s. He sees a caution flag go up, so he slows at a rate of -1.5 m/s^2 in 10.8 s. What is his final velocity?

Answers

Answer:

15.8 m/s

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 32 m/s.

Acceleration (a) = – 1.5 m/s²

Time (t) = 10.8 s.

Final velocity (v) =?

Acceleration is simply defined as the rate of change of velocity with time. Mathematically, it is expressed as:

Acceleration (a) = [final velocity (v) – initial velocity (u)] / time (t)

a = (v – u) /t

With the above formula, we can obtain the final velocity of go-cart driver as follow:

Initial velocity (u) = 32 m/s.

Acceleration (a) = – 1.5 m/s²

Time (t) = 10.8 s.

Final velocity (v) =?

a = (v – u) /t

– 1.5 = (v – 32) / 10.8

Cross multiply

(v – 32) = –1.5 × 10.8

v – 32 = – 16.2

Collect like terms

v = – 16.2 + 32

v = 15.8 m/s

Therefore, the final velocity of go-cart driver is 15.8 m/s.

A ball thrown vertically upward is caught by the thrower after 4.00 sec. Find the initial velocity of the ball and the maximum height it reaches.

Answers

Answer:

Initial velocity = 39.2m/s

Maximum height is 78.4m

Explanation:

Given

[tex]Time, t = 4s[/tex]

Solving (a): Initial Velocity

Using first law of motion:

[tex]v = u + at[/tex]

Where

[tex]v = final\ velocity = 0[/tex]

[tex]u = iniital\ velocity = ??[/tex]

[tex]a = acceleration = -g[/tex] [g represents acceleration due to gravity]

[tex]t = 4[/tex]

Substitute these value in the above formula:

[tex]v = u + at[/tex]

[tex]0 = u - g * 4[/tex]

[tex]0 = u - 9.8 * 4[/tex]

Take g as 9.8m/s²

[tex]0 = u - 39.2[/tex]

[tex]u = 39.2m/s\\[/tex]

Hence, initial velocity = 39.2m/s

Solving (b): Maximum Height

This will be solved using second equation of motion

[tex]s = ut + \frac{1}{2}at^2[/tex]

This becomes

[tex]s = ut - \frac{1}{2}gt^2[/tex]

Substitute values for u, t and g

[tex]s = 39.2 * 4 - \frac{1}{2} * 9.8 * 4^2[/tex]

[tex]s = 156.8 - 78.4[/tex]

[tex]s = 78.4[/tex]

Hence, the maximum height is 78.4m

What is the smallest part of a chemical compound that has all the properties

Answers

Answer:

D. A Molecule

Explanation:

The smallest particle of a compound that still has the properties of the compound is a molecule. It is composed of two or more bonded atoms.

The smallest part of a chemical compound that has all the properties of that compound is a molecule (option d)

In the world of chemistry, substances are composed of tiny units called atoms, and these atoms bond together to form chemical compounds.

Option A, a nucleus, refers to the central core of an atom and consists of protons and neutrons. While essential for an atom, a nucleus alone does not represent a complete chemical compound.

Option B, a mineral, is a naturally occurring inorganic substance with a specific chemical composition and a definite atomic structure. However, minerals are not the smallest parts of a chemical compound.

Option C, an atom, is the fundamental building block of matter. It consists of a nucleus (containing protons and neutrons) surrounded by electrons. While atoms are crucial for forming compounds, they are not the smallest unit that retains all the properties of a compound.

Therefore, the correct answer is Option D, a molecule. A molecule is a group of two or more atoms bonded together, representing the smallest part of a chemical compound that possesses all the characteristics and properties of that compound.

Hence the correct option is (d).
