Answer:
Like the three kanji characters that make up the word, kabuki consists of ka (singing), bu (dancing) and ki (skill). In addition to these three components, kabuki is characterized by unique stage sets such as a revolving platform that allows for nearly instant set changes and a runway that stretches into the audience.
The study of spectral lines from the messier 81 galaxy suggests that it is moving toward earth. identify the color toward which these spectral lines shift when visible light from the messier 81 galaxy is observed on earth.
The color towards which these spectral lines shifts when visible light from messier 81 galaxy is observed on planet Earth is a blue shift or violet.
What is a redshift?A redshift can be defined as a displacement (shift) of the spectral lines of astronomical objects such as messier 81 galaxy, toward longer wavelengths as a result of the Doppler effect.
In this scenario, we can infer and logically conclude that the color towards which these spectral lines would shift when visible light from the messier 81 galaxy is observed on planet Earth is a blue shift or violet.

An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The maximum displacement from equilibrium is a and the total mechanical energy of the system is e
An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The system's potential energy when kinetic energy of (3/4) E is (1/8) k A².
What is mechanical energy?Mechanical energy is the sum of potential energy and kinetic energy.
Total mechanical energy = P.E max = K.E max
Total mechanical energy = K.E +P.E
Given is the kinetic energy is (3/4)E.
E= (3/4)E + P.E
P.E = (1/4) E
Maximum potential energy =E = (1/2) k A²
Here. A is the maximum displacement and k is the spring constant.
The potential energy at kinetic energy of (3/4) E is
P.E = (1/4)E = (1/8) k A²
Therefore, the system's potential energy when kinetic energy of (3/4) E is (1/8) k A².

The noble gases are unreactive and stable. Which of the following explains why this is true?
They each have no electrons.
They have 8 electrons in their outer shell (except for Helium).
They have only neutrons in their nucleus
They have more electrons than other elements.
Answer:
They have 8 electrons in their outermost shell(except for Helium)
Explanation:
The noble gases are unreactive and stable because they have completely filled orbitals and have 8 electrons in their outermost shell.
Therefore
They have 8 electrons in their outermost shell(except for Helium)

Two charges are separted by a distance d and exert mutual attractive forces of f on each other. If the charges are separated by a distate of 2d what are the new mutual forces?
The new force between the charges when the distance become 2d will be F'=4F
What is electrostatic force?
When two charged particles are separated by the distance d then the force of attraction or repultion acts on the charged particle depending upon the nature of the charge whether it is positive or negative.
The formula for the electrostatic force is given by
[tex]F=\dfrac{kq_1q_2}{d^2}[/tex]
Now if the value of d becomes 2d then the formula will become:
[tex]F'=\dfrac{kq_1q_2}{(2d)^2}=\dfrac{kq_1q_2}{4d}[/tex]
[tex]\dfrac{F'}{F}=\dfrac{1}{4}[/tex]
[tex]F=4F'[/tex]
Hence the new force between the charges when the distance become 2d will be F'=4F

Mechanical energy is as much of potential and kinetic energy. Mechanical energy is never lost but only transformed from one form to another. As long as all the mechanical energy is as much as the potential energy then the kinetic energy is 0J. The mechanical energy of an object is found by summing its potential energy and kinetic energy.

Energy efficiency can either be achieved by either reducing the quantity of energy consumption to produce certain amount of products or producing increased number of products from the same quantity of energy.
Explanation:
Efficiency is a way of describing the amount of useful output a process or machine can generate as a percentage of the input required to make it go. In other words, it compares how much energy is used to do work versus how much is lost or wasted to the environment. The more efficient the machine, the less energy wasted.
For example, if a heat engine is able to turn 75 percent of the fuel it receives into motion, while 25 percent is lost as heat in the process, it would be 75 percent efficient. Out of the original 100 percent of the fuel, 75 percent was output as useful work.
the equation:
energy efficiency =useful output energy/total input energy

How long does it take light to reach Earth from an object on light-year away?
Answer:
The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
Explanation:
how long does it take sunlight to reach Earth? This sounds like a strange question, but think about it. Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. If the Sun suddenly disappeared from the Universe (not that this could actually happen, don't panic), it would take a little more than 8 minutes before you realized it was time to put on a sweater.
