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

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.

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.

How do I solve these problems?
Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

1200 W, 2000 W, and 720 W devices will be operated on 220 V at the same time. Calculate the current through each device.
Answer:
I₁ = 5.45 A
I₂ = 9.1 A
I₃ = 3.27 A
Explanation:
Electrical power is defined as the product of current and displacement.
[tex]P = VI\\\\I = \frac{P}{V}[/tex]
where,
P = Power of Device
I = current passing through the device
V = voltage across the device = 220 V
FOR P₁ = 1200 W
[tex]I_1 = \frac{1200\ W}{220\ V}[/tex]
I₁ = 5.45 A
FOR P₂ = 2000 W
[tex]I_2 = \frac{2000\ W}{220\ V}[/tex]
I₂ = 9.1 A
FOR P₃ = 720 W
[tex]I_1 = \frac{720\ W}{220\ V}[/tex]
I₃ = 3.27 A

Radioactive decay
Half-life
Radiometric dating
2. How does radioactivity affect Earth’s interior?
Answer:
Radioactive decay: is the process by which an unstable atomic nucleus loses energy by radiation.
Half-life: in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half.
Radiometric dating: is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Which best explains how Selena can correct her error? She can change the magnets so like poles are facing each other. She can change the arrows so they show current traveling in opposite directions on the sides of the loop. She can change the arrows so they show the magnetic field reversing direction between the magnets. She can change the magnetic poles so they are both on one side of the loop.
Complete question is;
Selena drew a diagram to show how current moves in a loop of wire that is placed between two magnets. At top left a piece of magnet labeled N and at top right a piece labeled S. Between these a square coil of wire with green arrows at its ends away from the magnets pointing away from the magnets. Red arrows point from N to S. Which best explains how Selena can correct her error?
A) She can change the magnets so like poles are facing each other.
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
C) She can change the arrows so they show the magnetic field reversing direction between the magnets.
D) She can change the magnetic poles so they are both on one side of the loop.
Answer:
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
Explanation:
Since the direction of the arrows point north and south whereas the magnets are east and west, it means the arrows are not pointing in the correct direction. To correct it she will have to make sure the arrows are pointing in opposite directions of the magnet via the sides of the loop.
Answer:
The answer is B

plz help This is for Rock formations...only 5 sentences if not more
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 mover pushes a 255 kg piano
with a 77.5 N force to the left, while
a second mover pulls the piano
48.7 N to the left. What is the
acceleration of the piano?
(Watch your minus signs.)
(Unit = m/s2)
Answer:
[tex]0.495ms^{-2[/tex]
Explanation:
According to the newton's second law of motion we can apply F=ma hear
Force = mass * acceleration
(assume the piano is moving left side )
←F = ma
[tex]F(pull) + F (push) = M * a\\77.5 + 48.7 = 255*a\\a = 0.495ms^{-2}[/tex]
Un muelle se alarga 30 centímetros cuando ejercemos sobre el una fuerza de 24 N a) calcula el valor de la constante elástica del muelle b) calcula el alargamiento del muelle al aplicar una fuerza de 60 N
Answer:
(a) k = 80 N/m (b) x = 75 cm
Explanation:
The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"
Given that,
Force exerted on the spring, F = 24 N
Elongation in the spring, k = 30 cm =0.3 m
(a) We know that, the force on the spring is given by :
F = kx
Where
k is spring constant
So,
[tex]k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m[/tex]
(b) When F = 60 N,
[tex]x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm[/tex]
Hence, this is the required solution.
