Explain how a star's absorption spectrum and the concept of red shift help support the Big Bang Theory.
Answer:
Red shift supports the big bang theory. ... The light from distant galaxies is red shifted (this tells us the galaxies are moving away from us) and the further away the galaxy the greater the red shift (this tells us that the more distant the galaxy the faster it is moving). Constellations look like they are moving because earth is rotating on it's axis.

A common isotope of Carbon has an atomic number of 6 and a mass number of 13. How many neutrons are in an atom of this isotope?
A. 6
B. 7
C. 12
D. 13
Answer:
D. 13
Explanation:
For most elements other than hydrogen, isotopes are named for their mass number. For example, carbon atoms with the usual 6 neutrons have a mass number of 12 (6 protons + 6 neutrons = 12), so they are called carbon-12. Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13).

Explanation:
Jenny and anne wanted to see who could throw the ball the hardest. they decided to each throw a ball against the wall as hard as they could and measured how far the ball rolled away from the wall. what might be the variables in this experiment;
Solution:
There are different type of collisions. In an inelastic collision, momentum is conserved and there is loss in kinetic energy while in an elastic collision, momentum is not conserved and there is no loss in kinetic energy.
During inelastic collision, the objects stick together while during an elastic collision, the objects separate.
When the ball is thrown against the stationary wall, there is momentum due to the force of impact. The distance at which the ball is rolled away from the wall depends on:
a) mass of the ball, b) velocity of the ball, c) mass of the wall d) type of collision (elastic or inelastic)

what is a transverse wave
Answer:
a wave vibrating at right angles to the direction of its propagation.
Explanation:
Answer:
In Physics, a transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave. A simple demonstration of the wave can be created on a horizontal length of the string by securing one end of the string and moving the other up and down. Light is another example of a transverse wave, where the oscillations are electric and magnetic fields that are at right angles to the ideal light rays that describe the direction of propagation.

Light is another example of a transverse wave, where the oscillations are electric and magnetic fields that are at right angles to the ideal light rays that describe the direction of propagation.
Transverse waves commonly occur in elastic solids, oscillations, in this case, are the displacement of solid particles from their relaxed position, in the direction perpendicular to the propagation of the wave. Since these displacements correspond to local shear deformation of the material, the transverse waves of this form are known as a shear wave. In seismology, shear waves are also known as secondary waves or S-waves.
Examples of Transverse waves
Some examples of transverse waves are listed below:
The ripples on the surface of the water
Electromagnetic waves
Stadium or a human wave
Ocean Waves
The secondary waves of an earthquake

The water level at the beach changes on a regular basis. What is the primary force that causes these changes in water levels?
Explanation:
The water level at the beach changes on regular basis because of high and low tides in the sea. The high tide and low tide in the sea is because of moons gravitational force on Earth. The tide are low or high depends upon the differences in how much the moon's gravity pulls on different parts of Earth. Places where pull is less experience low tide whereas places where pull is more experience high tide.

As the kinetic energy of the molecules in a substance increases, the
a. temperature of the substance increases.
b. temperature of the substance decreases.
c. potential energy of the substance changes.
d. temperature remains the same.
Answer:
a. temperature of the substance increases.
Explanation:
Temperature is defined as a measure of the average kinetic energy of a substance, so as one rises, so will the other. They are directly proportional.
As the kinetic energy of the molecules in a substance increases, the temperature of the substance is also increases because kinetic energy and temperature is proportional to each other.
Relation of kinetic energy and temperatureKinetic energy is directly related to temperature which means if kinetic energy is increased, the temperature of the solution is also increased and vice versa.
So we can conclude that As the kinetic energy of the molecules in a substance increases, the temperature of the substance is also increases because kinetic energy and temperature is proportional to each other.

C.
Can the wave travel through a vacuum?
D.
Can the wave travel through a liquid?
Answer:
A. Can the wave transfer matter?
Explanation:
EMW is made by vibrations of the charged particles and they work on a mechanical waveform. The energy is transferred through a vacuum and thus they need a medium to pass the energy. Thus in order to transport the energy from one place to another, such as a sound wave. Hence first she should have knowledge about the chemical and physical properties of the waves such as can they transfer matter.Which statements about acceleration are true?

Phases of Matter Activity
Now it is your turn to show what you know about phases of matter and thermal energy transfer! Your task is to create a presentation to explain the transformation of a substance as it changes phases. You may choose to write a story or create a comic strip. For your story or comic, you will create a main character and detail the adventure as your character is exposed to thermal energy, causing it to undergo phase changes from a solid, to a liquid, to a gas. You may create your own comic strip using drawings, presentation software, or this comic strip template.
Your presentation must include the following:
title and introduction of your character, including what substance the character is made of
source of thermal energy your character encountered (conduction, convection, and/or radiation)
detailed description and/or diagram of the particle transformation from solid to liquid phase
detailed description and/or diagram of the particle transformation from liquid to gas phase

The title is the journey of the ice cube. (change it if you want)
Main character - ice cube
There was an ice cube made by the water from the freezer in an ice shop.
The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.
That is the end.
You can add, edit or even not consider this one. But this is just an example to spark up your ideas. Sorry if I made some English mistakes.

Answer:
adaptive optics.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.
A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.
The technique called adaptive optics uses a high-speed computer to monitor atmospheric distortion and adjust the optics of a telescope to partially compensate for the seeing.
Basically, adaptive optics is used by astronomers to correct the distortions caused by the turbulence of the atmospheric conditions of the Earth in real-time, so as to have an image that is as sharp as anyone taken in space.
