Based on the degree of refraction from least to most refracted, the colors are as follows: Red, Orange, Yellow, Green, Blue, Indigo, Violet.
What is refraction of light?Refraction of light is the bending of light rays as they cross the boundary between two media of different densities.
White light consists of seven colors of light; Red, Orange, Yellow, Green, Blue, Indigo, Violet.
The red color has the shortest wavelength and is the least refracted while violet color has the longest wavelength and is most refracted.
Therefore, based on the degree of refraction from least to most refracted, the colors are as follows: Red, Orange, Yellow, Green, Blue, Indigo, Violet.

A student lifts a 1.4-kg box of magazines vertically from rest with an upward force of 52.7 N. The distance of the lift is 1.6 meters. Find the
total work done on the box
-64.41
Answer:
The work done on the box is 21.952 Joules
Explanation:
The given parameters are;
The mass of the box of magazines, m = 1.4 kg
The upward force with which the student lifts the magazine = 52.7 N
The distance (height) of the lift, h = 1.6 meters
The work done on the box = The potential energy gained by the box of magazine, P. E.
Potential energy gained by elevation, P. E. = Mass, m × The acceleration due to gravity, g × Height, h
Where;
The acceleration due to gravity, g = 9.8 m/s²
∴ P. E. = m × g × h = 1.4 kg × 9.8 m/s^2 × 1.6 m = 21.952 Joules
The work done on the box = The potential energy gained by the box of magazine, P. E. = 21.952 Joules
The total work done on the box is 21.952 Joules
The workdone on the box is equal to the potential energy possessed by the body. Mathematically;
[tex]W=P.E=mgh[/tex]
m is the mass of the bodyg is the acceleration due to gravityh is the heightGiven the following parameters
m = 1.4kg
g = 9.8m/s²
h = 1.6m
Substitute the given parameters into the formula:
[tex]W = 1.4 \times 9.8 \timees 1.6\\W=21.952Joules[/tex]
Hence the total work done on the box is 21.952 Joules

help pls !!!!! which statement is true for chemical reactions but not for nuclear reactions?
Answer:
Explanation:
anyways
B) The nuclei of the atoms involved stay the same .
What are nuclear reactions ?
Nuclear Reactions are processes in which one or more nuclides are produced from a collision between two nuclei or one nucleus and a subatomic particle.
In a nuclear reactions the elements can change from one to another. Nuclei can break apart to form smaller elements. Nuclei can fuse together to make heavier elements. Neutrons can turn into protons and protons into neutrons. But this does not happen in a chemical reaction only composition of elements changes and rearrangement of the molecular or ionic structure of a substance take place in a chemical reaction
hence , correct answer is B) The nuclei of the atoms involved stay the same .

The graph shows the amplitude of a passing wave over time in seconds (s).
What is the approximate frequency of the wave shown?
Answer:
Option B. 0.3 Hz
Explanation:
From the question given above, the following data were obtained:
Period (T) = 3 s
Frequency (f) =?
Frequency is related to the period according to the following equation:
Frequency (f) = 1 / period (T)
f = 1/T
With the above formula, we can obtain the frequency wave as illustrated below:
Period (T) = 3 s
Frequency (f) =?
f = 1/T
f = 1/3
f = 0.3 Hz
Therefore, the frequency of the wave is 0.3 Hz

1. A rug sits in a sunny place on the floor for a long time. Kiara thinks that light from the sun can
cause the rug's color to fade over time. Can light from the sun cause the rug's color to fade?
a
No. Light is not a physical thing, so it cannot change physical things like rugs.
b
No. Light can only change things by warming them up, so it cannot cause the rug's color to
fade.
Yes. The rug can take in energy from the light, causing the rug's color to fade.
d
Yes. Light from the sun can pull energy out of the rug, causing the rug's color to fade.
Answer:
yes
Explanation:
the rug can take energy from the light causing the rug's color to fade
Yes, Kiara is right because the rug can take in energy from the Sun's light, thereby causing the rug's color to fade: C. Yes. The rug can take in energy from the light, causing the rug's color to fade.
The Sun is typically characterized by nuclear reactions that usually takes place or occur at its center, which eventually result in the release of radiant (heat) energy and electromagnetic radiation into planet Earth.
Although, these radiant (heat) energy and electromagnetic radiation from the Sun are essential and very important to life on planet Earth.
However, a disadvantage of radiant (heat) energy is that when taken in by conducting materials such as rugs, it causes their color to fade (change) over time.
In conclusion, Kiara is absolutely right in her thinking because light energy (sunlight) from the Sun can cause the rug's color to become faded over time.

Answer:
a) i) In the first image we can see that almost the whole island is covered with forest. While in the second one, we can see that near the edges of the island the amount of forest cover has ben decreased. This may be because is easier to cut the trees near the shore of the island.
ii) There are different motives to cut the trees, one may be to build constructions. People need to remove the trees in an area in order to be able to build in there. Also, the trees can be used in a lot of different ways as raw materials.
b) i) Less forest cover also means that there is a smaller habitable area for the local life (animals, insects, etc...). Then the animals need to be more "cramped", and this can affect greatly the life of them.
ii) There will be less food and fewer natural resources for the locals.

Explanation:
The true statement about gravity is that it is the force of attraction between two objects with masses and also, based on the distance between these objects.
Gravity is a force of attraction.
The best scientific overview of the force of gravity is given by the Newton's law of universal gravitation which states that "the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them",
So, gravitational force of attraction is dependent on mass and the distance between two bodies.

Explain how the Law of Conservation of Energy applies to the energy
transformations that occur from the outlet charger to the ringing phone.
Answer:
The mobile electric energy gets converted into chemical energy while charging.
Explanation:
According to the law of conservation of energy, no energy is destroyed when one form of energy is transformed to another in the process as energy cannot be created or destroyed. As a result, total amount of energy remains same before and after any kind of transformation.
Generally, lithium ion batteries are used in mobile phones. In such batteries, the electricity is stored in the ionic structure by the chemical changes.
The mobile electric energy gets converted into chemical energy while charging.

An object is 45.0 kg here on Earth. What is its mass on Jupiter if the acceleration
due to gravity on Jupiter is 24.79 m/s 2?
A.) 1.82 kg
B.) 45.0 kg
C.) 1120 kg
D.) 441 kg
Answer:
B. 45.0 kg
Explanation:
On earth the object has ;
Mass = 45 kg
acceleration = 9.81 m/s²
On Jupiter, acceleration is 24.79 m/s²
The mass of this object on Jupiter will be 45 kg. It will not change. Mass of an object will only change when you remove part of the object from it or add to it another part. The mass is the same on Earth and on Jupiter. However, due to increased acceleration on Jupiter , the weight will change/ increase because;
Weight = mass * acceleration
On Earth
Weight of the object will be : 45 * 9.81 = 441.45 kg
On Jupiter
Weight of the object will be : 45*24.79 =1115.55 kg
