If you can prove to your teachers that you are smart enough to move up a grade, then yes. Sometimes you do have to take a quiz or two to prove your smarts, or just get all As, but it really depends on school and area. Hope you make it.

Explanation:

Having all As does not represent knowing everything there is to learn in 8th

Correct  a₂ > a₁

Explanation:

Given:

Tony  mass = m₁ = 50 kg

Sam mass = m₂ = 45 kg

According to Newton's second law, the formula for calculating force is:

F = m · a

In this case we have the same force for both

F = m₁ a₁ = m₂ a₂  => a₁ / a₂ = m₂ / m₁ = 45 / 50 = 9 / 10 = 0.9

a₁ = 0.9 a₂  => a₁ = 90% of a₂ => a₂ > a₁

a₂ > a₁

God is with you!!!
