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.

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.

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.

how can magnets produce electricity?
Answer:
Magnetic fields can be used to make electricity
Explanation:
Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy
Explanation:
If a magnet is moved back and forth through a coil of wire current can be made to flow through the wire. This is the idea behind electric generators and transformers.

Why do the number of organisms in a group change from the first step to the last step of a dichotomous key?
A
The number of organisms decreases because the number of common characteristics of the organisms in a group increases.
B
The number of organisms increases because the number of common characteristics of the organisms in a group increases.
C
The number of organisms is cut in half because the number of common characteristics of the organisms in a group decreases by half in the last step.
D
The number of organisms stays the same because the number of common characteristics of the organisms in a group decreases by half in the last step.
Answer:
I think its B. The number of organisms increases because the number of common characteristics of the organisms in a group increases.
Explanation:
Hope this helps
The number of organisms in a group increases from the first step to the last step of a dichotomous key because the number of common characteristics of the organisms in a group increases.
What is a dichotomous key?A dichotomous key is a tool used in biology to identify organisms based on similarities in their structure and characteristics.
In a dichotomous key, the number of organisms in a group change from the first step to the last step
The reason for this change is because the number of common characteristics of the organisms in a group increases.
Therefore, the correct statement is "The number of organisms increases because the number of common characteristics of the organisms in a group increases", option B.

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. 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.
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.
