Answer:
the name and the units of the vertical axis. Explanation: As you see the horizontal axis shows that the independent variable is Temperature and that it is reported in °C.
Explanation:
Answer
The horizontal axis reveals to us that the independent variable is temperature which is reporting in C. We know that but what we dont know is the name or the untis on the vertical axis. Also a nice title and chart by it will help as well. A legend as well to explain what the colors even mean.

Two resistors, R1 and R2, are
connected in parallel. R1 = 35.0
ohms, and the equivalent resistance
of the combination is 14.5 ohms.
What is the value of R2?
(Unit = ohm)
Answer:
The value of R₂ is equal to 24.75 ohms.
Explanation:
Given that,
Two resistors, R₁ and R₂, are connected in parallel.
The equivalent resistance is 14.5 ohms
We need to find the value of R₂.
When two resistors are connected in parallel. The equivalent resistance is given by :
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{14.5}=\dfrac{1}{35}+\dfrac{1}{R_2}\\\\\dfrac{1}{R_2}=\dfrac{1}{14.5}-\dfrac{1}{35}\\\\\dfrac{1}{R_2}=0.04039\\\\R_2=\dfrac{1}{0.04039}\\\\R_2=24.75\ \Omega[/tex]
So, the value of R₂ is equal to 24.75 ohms.
What is a scientific theory?
O Alaw that is always true
O A hypothesis about nature
O An educated guess based on observations
O An explanation of how the natural world works
Answer: An educated guess based on observations
Explanation: A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

If Europium (Eu) undergoes proton decay and loses 3 protons, which element will it become?
Answer:
Neodymium (Nd)
Explanation:
An element is made up of atom, which contains three subatomic particles namely; proton, electron, and neutron. In a neutral atom, the number of protons determines the atomic number of that element and the atomic number of an element is the identity of that element in the periodic table.
Hence, a change in the proton number of an element means a change in the atomic number and ultimately a change of that element. In this question, Europium (Eu) element with atomic number, 63, loses three protons. This means that that atom now has 60 protons, which denotes the atomic number of another element called Neodymium (Nd).
Therefore, Europium (Eu) element has become Neodymium (Nd) due to loss of protons.
Which statement correctly describes magnetic field lines around a bar magnet?
Answer:A
Explanation:I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance.
They point away from the north pole and towards the south pole, is the statement correctly describing magnetic field lines around a bar magnet.
What is a bar magnet?A bar magnet is a rectangular section of an item that has permanent magnetic qualities and is made of iron, steel, or any other ferromagnetic material or ferromagnetic composite.
It has two poles, one north, and one south, and when hanging freely, the magnet aligns itself such that the north pole faces the earth's magnetic north pole.
They point away from the north pole and towards the south pole, the statement correctly describes magnetic field lines around a bar magnet.
Hence statement B correctly describes magnetic field lines around a bar magnet.

Qué esperas que pase cuando las partículas alfa de poca energía se acerquen a un núcleo con muchos protones?
Answer:
Sufrirá una deflección en su recorrido.
Explanation:
Las partículas alfa son nucleos de He (dos protones mas dos neutrones), por lo tanto tienen una carga neta positiva.
Ahora, al acercarse al nucleo de un átomo con muchos protones y con baja energía, la partícula alfa sufrirá una deflección en su recorrido debido a las fuerzas de repulsión electrostática que siente la partícula, ya que el nucelo posee caraga positiva.

A 80 kg person buys a scale at a mall that reads weight in Newtons and can’t wait to try it out, so they open the scale on an elevator. What would the scale read if the elevator was moving upward at 6.2 m/s2?
Answer:
The scale read 1280 N.
Explanation:
Given that,
The mass of a person, m = 80 kg
We need to find the scale reading when the elevator is moving upward at 6.2 m/s².
We know that, when an elevator moves up, the reading on the scale is given by :
N-mg=ma
N=m(a+g)
Put all the values,
N = 80(6.2+9.8)
= 80(16)
= 1280 N
Hence, the scale read 1280 N.

Explanation:
7. The Voyager 1 space probe was launched in the 1970's and is now the furthest
man-made object from earth - it has actually left the solar system. At its current speed it
could travel across the US, a distance of about 4500 km in 265 seconds (a little less
than 5 minutes!) What is its average speed in kilometers per second?
PLEASE HELP I NEED THE FORMULA AND ANSWER THANK YOU!!
Answer:
v = 16.98 km/s
Explanation:
Given that,
Distance, d = 4500 km
Time, t = 265 s
We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,
[tex]v=\dfrac{4500\ km}{265\ s}\\\\=16.98\ km/s[/tex]
So, the average speed is 16.98 km/s.

For this assignment, consider the processes that create coastal rock formations. While these processes create beautiful and interesting rock formations, they are also often highly destructive. Think for example what could happen to a town that is near the sea and has buildings being exposed to the same forces that create sea cliffs, arches, and stacks. How do you think those buildings stand up against the forces of the waves? Make a discussion posting to describe what you think happens to buildings exposed to sea erosion and then suggest ways that the destruction associated with this force can be stopped for people who live in towns near the coast.
After you make your post, comment on at least one of the posts of your classmates.

a group of engineers have launched a space probe from earth that will land on the surface of Mars. how will the force of gravity from mars affect the space probe?
A) the force of gravity from Mars will not pull on the space probe until it reaches the planets surface.
B) the force of gravity from Mars will stop pulling on the space probe when it reaches the planet
C) the force of gravity from Mars will pull more strongly on the space probe as it gets closer to Mars.
D) the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is
Answer:D
Explanation:
The force of gravity from Mars will pull on the space probe the same amount no matter how far away it is, so option D is correct.
What is gravity?All material objects in the universe are subject to the force of gravity, also known as gravitation. The force of gravity tends to draw any two non-zero mass objects or particles toward one another. Subatomic particles and galaxy clusters are both affected by gravity, as are objects of all sizes.
Due to the law of gravity, or gravitation, which draws all objects with mass in its vicinity toward it, Mars' gravitation is a natural occurrence. Due to the planet's lesser mass, its gravity is weaker than that of Earth. On Mars, the gravitational acceleration fluctuates, but on average it is 3.72076 m/ s² (or around 38% of Earth's).
Therefore, the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is.

When rutherford bombarded thin gold foil with a-particles,he found that some a-particles were deflected through large angles. Which statement explains this deflection?
Answer:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Explanation:
In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.
The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,
V_atom / V_nucleo = 10⁴
Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.
In summary, the phrase that describes the process is:
the nucleus of the atom you have conserved almost all its mass in a very small volume
