Cars 'A' and 'C' look like they're moving at the same speed. If their tracks are parallel, then they're also moving with the same velocity.
Hey there!
Alright, it looks like you've got the second question on the top right, but I can't figure out the answer you've got for the first.
Using Newton's Second Law Of Motion, we have:
F = ma
We plug in our values:
F = 5(1)
That would give us 5 Newtons of force.
For the last one:
Even if two balls are given the same acceleration, the determining factor is <em>weight.</em> If a ball is lighter, it needs less acceleration to go faster. If it's larger, it needs more to make it go at that same speed. That's why that 5 newtons makes sense because it's 5 kilograms as opposed to 0.6 kilograms. It's heavier, and needs more force.
Hope this helped!

Below is an attachment containing the solution.
Answer
given,
V = 2 L
the left is an ideal gas at P = 100 k Pa and T = 500 K
mass is constant
Pressure is same because it's not changing due to process
m = 1.39 x 10⁻³ Kg
Answer: B
Explanation:
Answers A and C are examples of physical weathering while B is chemical weathering when water and lime mix it creates a reaction
