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

happen to the magnets?
O A. They will be repelled because they are in each other's magnetic
field.
B. They will not move because they have only half of a magnetic
field.
C. They will not move because they have very small gravitational
fields.
D. They will be attracted because their electric fields will add
together
Answer: A. They will be repelled because they are in each other's magnetic
field.
Explanation: Apex and gravity and electrical don't have effect on magnets magnetic field.
The statement that described the happening to the magnets should be that they will be attracted because they are in each other's magnetic.
What is a magnet?Magnet refers to the piece of iron or other material that comprise of the atoms also it inbuilt the magnetism properties like attraction of other type of iron objects. In the case when the two magnets shoud be placed near to each other also their north poles should be faced each other so it should be attracted since it is considered as the each other magnetic.

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?
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 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
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

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?
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.
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

of that compound
A. A nucleus
B. A mineral
C. An atom
D. A molecule
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).

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
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.
