1. How would increasing the magnitude of the charges on two charged particles and decreasing the distance between the particles affect the strength of the electric force between the particles?
Answer:
Explanation:
Coulomb's law of electrostatics states that the Coulomb force between two charged objects is proportional to the size of the charges, and inversely proportional to the separation distance. The constant of proportionality is called Coulombs constant. In math words, it says:
[tex]F=kq_1q_2/r^2[/tex]
If you decrease the magnitude of the charges, the total Coulomb force would also decrease. If the distance between the particles was decreased, the total Coulomb force would increase. A smaller term in the denotator would cause the Coulomb force to increase.

What does energy and Newton's Laws (all three) have to do with roller coasters?
Answer:
Potential Energy is the energy that is waiting to be released like at the top of the roller coaster, Kinetic energy is the energy that is moving the rollercoaster downhill fast.
Three Laws:
The rollercoaster will rest at the top, and then the gears will make it move downhill, and make it stop.
The gears make the rollercoaster move, and in reaction, it pushes back on the gears.
Answer:
Newton's law has every thing to do with roller coasters.
in the case that you have given, the first law states that any object when given an force will keep moving until there is no opposing force acting upon the moving object. when the roller coaster is moving the opposing force here can be the frictional force that is acting upon the coaster that is the breaking system as the train comes to the station to stop a the end.
to summarize
Newton's first law: any object will keep moving until there is an opposing force acting upon it
the opposing force in the coaster is the breaking system..

2. Investigate and apply Newton’s Laws to football:
a. Watch the following videos
b. Describe all the ways that Newton’s Laws can apply in the game of football
(Remember to talk about ALL THREE LAWS).
PLEASE HURRY AND HELP.
Newton's First Law
Newton's first law states that an object thats moving wants to stay moving and an object that's not moving doesn't want to move. An example of Newton's First Law in football is throwing the ball. When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it.
Newton's Second Law
Newton's Second Law states that objects with more mass require more force to move. An example of Newton's Second Law in football is tackling. Bigger players require more force to move. And smaller players require less force to move. The more inertia and mass the object has that is moving the other object, and the less friction the object that is being moved has on the ground will make it easier to move.
A big football player has more mass than a smaller football player so he will require more force to be moved.
He needs to put more force on the other player than a chair to move him because the player has more mass.
Newton's Third Law
Newton' Third Law states that if there is an action there will be equal and opposite reactions. An example of Newton's Third Law in football is stiff arming. when you push another player away from you while running. It will push them away while also pushing you away from them. The force of the other player moving at him force is put on the player too. Also how much inertia the other player has increases the amount of force put on the player stiff arming.
when he stiff arms he pushes the other player away from him and him away from the other player.
When he puts force on the ball then releases it, it continues to fly forwards.
When he pushes the ball forward and releases it will continue to move.
because he pushes the other player away the other player moving at him also puts force on him.

Assume that a wave has an amplitude of 1 unit and transports 2 units of energy.
How much energy will the wave transport if its amplitude increases to 4 units?
HELP ME PLEASE!
Answer: 8 units
Explanation: 1 unit = 2 units. That means that a wave transports double the amount of units.
4 units = 8 units because 4 x 2 = 8
Light bending at a boundary is caused by differences in the speed of light in different materials. The greater the difference in speed, the more the light bends. You looked at three materials in this activity—air, water, and glass. In which two materials is the speed of light the most similar? Explain your answer.
Answer:
How much does light bend? When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
Answer:
When light traveled between water and glass, the light didn’t bend much. The speed of light in these two materials is the most similar.
Explanation:

A car travels 40 miles north in the first 40 minutes of a trip. The same car travels 30 miles west in the next 30 minutes of the trip.
What is true about the motion of the car?
----
A.The car is traveling at a constant speed.
B.The car does not accelerate during the trip.
C.The car is traveling at a constant velocity.
D.All of the above.
Answer:
A. The car is traveling at a constant speed
Explanation:
When the car was moving north, it was moving 40 miles in 40 minutes. The rate is the same for when the car was traveling west, therefore, the car was traveling at a constant speed.
This experiment is to see if water flows faster out of a smaller can or a larger can.
You will need:
• two cans (one quite small like a soup can and the other large, like a juice, can.)
Follow these steps:
A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.
B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?
C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?
D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?
ANSWER A B C AND D CORRECTLY!!!
the water flows faster out of a smaller can than it does a larger can.
Answer:
A&B: The stem of the water does not shoot out the same distance because one can have less water and the other can have more water and the can with less water have more pressure that making the can shoot out further than the can with more water.
C: Less water will come out of the two cans because they are compressed together so all of the water is trying to come out all at the same time.
D:All of the water in the can started coming out all in one small stream.

2. What happens to the wavelength as the frequency increases?
Answer:
the wavelength gets shorter
Explanation:
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

A physicist hangs a 150-g object on a spring whose spring constant is a value of 13.22 Newtons/meter and has a spring force of 20N. How far does the spring stretch?
Answer:
so the answer is this because the answer is that
Explanation:
and the reason why the answer is this and that is because the answer is that
The spring stretch to a length of 1.51 m. Spring force is the product of the spring constant and elongation.
What is spring force?The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is;
F = kx
The given data in the problem is;
F is the spring force =20 N
K is the spring constant= 13.22 N/m
x is the length by which spring got stretched = ? m
The spring force is balanced by the weight:
F=Kx
20 N= 13.22 N/m × x
x=1.51 m
Hence, the spring stretch to a length of 1.51 m.
