Effort arm = 1.20m

What will be the Mechanical advantage ?
(equation must be shown)

the answer to your question is high voltage and high currency

i believe it is b. what was the cause of the big bang

hope this !

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.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
