REAL ANSWERS Question:Static friction percent error& trying to find the expected static friction value

Info: How do you calculate the static friction percent error for each?

Weight is 277.4g
Static force magnitude 1.1N
Experimented Static Coefficient .5

Weight is 799.8g
Static force magnitude 3.5N
Experimented Static Coefficient .45

What is known:
Ik it’s ((experimented-expected)/expected)* 100 to get the percent error but I don’t know how to calculate the expected

Q: What is the EXPECTED static COEFFICIENTS (decimal 0-1)for both weights and what is the percent error? How did you get to it?

(.5-(expected))/expected

(.45-(expected))/expected

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

the awnser is d you right bro
