Select the statement that best describes how fundamental forces relate.
All forces begin equally and become varied. The object on which they are acting and the distance to that object determines the amount of force.
Weak nuclear and magnetic forces are different because magnetic forces are associated with unmoving charges, and weak nuclear forces are associated with moving charges.
All forces are related to the mass of the object on which they are acting. The larger the mass, the weaker the forces become.
Electromagnetic and gravitational forces are similar because they both include the interaction between attractive forces.
Answer:
Magnetic and electrical forces are similar because they are both related to the interactions between charged particles" best describes how the forces relate.

1. Essential Question: If you know your Constant of Proportionality, how can you write your equation?
2. How can you use your equation to solve problems if certain information is known?
3. How do you know if a table represents a proportional relationship?
4. Where is the COP found in a graph?
PLEASE HELP ME!!!
Answer:
i only know the answer for 3
Step-by-step explanation:
You can know if your table is showing a proportial relationship if all the things inside the table (x,y) are equivalent.
for example, lets say the table shows:
x I 2 3
y I 4 6
we can see that they are proportional because they are both equal to 1/2

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Answer: Its a positive number
Step-by-step explanation:
If you look it says she is at sea level which is 0 and she is going up 12.3 feet so its positive.

WILL GIVE BRAINLIEST (someone help me with this pythagorean theorem) im in 8th grade and just started this and im confused ;c
plzzzzz
Answer:
Step-by-step explanation:
For #1. The equation is a^2 + b^2 = c^2. If it’s a right triangle. Both sides will equal out. A and B are sides, and C is the slanted side (hypotenuse) so you’d do
13^2 + 84^2 = 85^2
169 + 7056 = 7225
7225= 7225
hope that helps you figure out the rest.
Answer:
the sum of the squared sides of a right triangle equals the length of the hypotenuse (the longer side) squared.
so square both sides and add them then square the longer side and if they equal each other it is a right triangle.

Answer:
Have such a good day and dont let what other people say get 2 u.
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Step-by-step explanation:
the points (0.5, 1/10) and (7, 1 2/5) are on the graph of a proportional relationship
A. what is the constant of proportionality
B. Name one more point on the graph
C. Write an equation that represents the proportional relationship
The constant of proportionality is 1/5 and the equation of the line is y = (1/5)x
A linear equation is of the form:
y = mx + b
where m is the constant of proportionality, b is the y intercept, y, x are variables.
Given the points (0.5, 1/10) and (7, 1 2/5), hence, the equation of the line is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-\frac{1}{10} =\frac{\frac{7}{5}-\frac{1}{10} }{7-0.5} (x-0.5)\\\\y=\frac{1}{5} x[/tex]
At x = 0, y = 0. Hence (0,0) is a point on the graph.
Hence the constant of proportionality is 1/5 and the equation of the line is y = (1/5)x

Pat's chickens lay between 18 and 25 eggs per week. pat eats two eggs per day and feeds remaining eggs to his dogs.
complete the inequality that best describes the number of eggs hot dogs eat per week
Answer:
14>(18-14)(25-14)
Step-by-step explanation:
The required expression of the inequality is given as 16 < x < 23.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Suppose the number of eggs eaten by hot dogs be x.
Then, the total number of eggs is x + 2.
As per the question the inequality can be written as follows,
18 < x + 2 < 25
Subtract 2 from all parts of the inequality to get,
18 - 2 < x < 25 - 2
=> 16 < x < 23
Hence, the inequality that best describes the number of eggs hot dogs eat per week is given as 16 < x < 23.

Vavilen inflated a huge balloon in 191919 minutes. Then he poked a hole in the balloon so that it slowly leaked air out until it was completely deflated.
The rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon. It took the balloon 383838 minutes to completely deflate.
At what rate did Vavilen inflate the balloon, and at what rate did the balloon deflate?
Choose 1 answer:
A) There is not enough information to determine exactly how fast Vavilen inflated the balloon or how fast the balloon deflated.
B) The given information describes an impossible situation.

Answer:
4x+10=26, x=2
Step-by-step explanation:
x is the expoint, and you have to multiply the expoint by the base number
4 x 4= 16
the reason why you are multiplig 4 by 4 is because the expoint told you how many times you needed to multiply the base number by
4^(2)= 16 + 10 will equal 26
