2. The angle if refraction is always less than the angle of incidence as shown in the table. If you were to calculate the averages of all 3 test, it would still be smaller than the angle of incidence.
3. The angle of refraction is always less than the angle of incidence because the light ray must be moving from a optical density than air hence the light ray could seem bended. This is because the the speed of a wave is determined by the medium through it is passing. When light speeds up as it passes from one material to another, the angle of refraction tends to be larger than the angle of incidence. An example of this would be when light passes from water to air or glass to water. This change also makes the image look shifted to the side.

Answers
How do you know when an object is moving at a constant speed or a changing speed?
Answers
Answer:
The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. The steeper the slope of the line the greater the acceleration. If the line slopes upward from left to right, this means the object is speeding up.

What are distillation and evaporation most often used to separate in a science lab and why?
A. Solutions because the particles in solutions are too small to separate by other means like filtering or your hands.
B. Magnetic substances that have been mixed with substances that dissolve because the distillation machine is metal.
C. Substances with high melting points because the distillation process creates high temperatures and can separate through melting.
D.Simple mixtures because the particles in mixtures are too small to separate by other means like filtering or your hands.

I might give brainliest: Please help, I have one question: why are there some differences when measuring something with a measuring tape and measuring something with an app?
Answers
-the scale will be different
-one may be more accurate than the other
-technology can sometimes have bugs or other factors such as a bad camera quality that might give false results
-using a measuring tape could cause some limitations such as how much you can measure
-using an app may allow you to measure longer distances due to a more endless resource instead of something materialistic

A spring having a spring constant of 180 N/m is stretched 0.51 m from its equilibrium position. How much elastic potential energy does the spring possess?
Answers
Answer:
23.41 N
Explanation:
Formula to find elastic potential energy is, P.E=0.5*k*delta x^2
Where, P.E. = Elastic potential energy
k is the spring constant
delta x is the length of the stretched spring.
So, P.E.=0.5*180*0.51^2 = 23.41 N
potential energy stored in the spring at the position
stretched by 16.5 cm.
Since you know the spring constant k, 144 N/m and
the spring stretch from the equilibrium position x, is
16.5 cm, or 0.165, you find the spring's potential

1. Examine at least three different batteries at home or at a store, each with a different voltage. Download the battery chart and fill it in showing the type of battery (alkaline, NiCd, etc), the voltage, the size, and the use for which each battery is designed. Why do you think they are different in size and voltage? Link: https://s3.amazonaws.com/content.accelerate-ed.com/Secondary/docs/PhysicalScience/battery_chart.pdf
2. Examine two items that use more than one battery, such as a flashlight, a 2-way radio, or a battery-operated toy. Look at the arrangement of the batteries in the item. Are they connected in series? For each item, state the number and type of batteries, the voltage of each battery, and the total voltage produced.

Describe the difference between global knowledge and personal ideas.
Answers
Answer:
Global knowledge is information that is widely accepted and been proven as the truth. It is information that may not necessarily have a source because it is common knowledge and not easily attributed to a certain source. Personal ideas are original to the author and may not be widely accepted. It is important to give credit to others by citing their work to acknowledge that this is not your own findings but rather someone else's. It is plagiarism to use someone else's work as your own without giving credit to their work. -W0lf93

Answers
Answer:
Sound travels the slowest through gases because the particles of a gas are closer together.
Explanation:
Because the molecules of gases are farther apart which makes it slower vs solids whereas their molecules are closer together which makes it faster
Sound travels the fastest through gases because the particles of a gas are farthest apart.
Is it possible for a wave to have a long wavelength but high frequency?
Answers
Answer: The frequency of a wave is inversely proportional to its wavelength.
Explanation: That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
How does the scientific meaning of the words work, energy, force and efficiency compare to their every day meaning? State the similarities and differences? need answer asap. Thank you!
Answers
Answer:
Force
If you're taking classical physics, simply stated, a force is a push or a pull of some sort. But there is one other very important thing to understand about Force. A true Force is always an interaction (at least from a classical perspective). That means that forces always come in pairs. This is stated in Newton's Third Law (equal and opposite forces). Every action must have a reaction. This is required for all true forces. Another consequence of this is that force is a vector, meaning it has a magnitude and a direction. The action and reaction will always be opposite in direction.
A lot of people will say F=ma. This is true. However, it is important to keep in mind that this definition is a calculational tool. It is more precise to say the Sum of all forces=ma. The point is that ma is not a force. Forces are things like weight, tension, normal, friction, gravity, electrostatic, magnetic, and various other applied forces. The sum of forces on an object equals the product of its mass times its acceleration.
It is important to keep in mind that the force is on the object that accelerates. Another way to state this is that objects cannot accelerate themselves. You cannot push yourself back (or forwards). But if you push a heavy object like a desk forwards, then the desk can push you back.
Energy
There are many kinds of energy. There are two important things to know.
Energy is the ability to do work. It doesn't mean work is being done, but that work can be done. (So you can see there is an intimate relationship between work and energy).
Energy is conserved. That means the total amount of energy is always constant. If the energy is a system changes somehow, that means some work was done in order to move the energy from one system to another.
Energy is also a scalar (given that Work is a scalar).
Type of machine. For each example, decide if it changes the size of the
force, if it changes the distance the force acts, and if it changes the
direction of a force. Some machines may change the force in more than
one way (these have an *) and will each have 2 answers.
