The process of <u>scientific method</u> involves making hypotheses , driving predictions from them as logical consequences , and then carrying out experiments or empirical observations based on those predictions. A hypotheses is a conjecture , based on knowledge obtained while seeking answers to the questions.
Explanation:
Using Newtons second law on each block
F = m*a
Block 1

Block 2

Block 3

Solving Eq1,2,3 simultaneously
Divide 1 and 2

Put Eq 4 into Eq3

Put Eq 5 into Eq2 and solve for a

Substitute back in Eq2 and use Eq4 and solve for T2 & T1

I believe it’s B but I suggest u chec
Yes it helps improve flexibility
Dead animals from million of years ago in the crust being exposed to heat and pressure breaking down into fossil fuels. The reason it is considered non-renewable is because the amount of time it takes to from these fuels takes way longer than any human could ever live.<span />
