    Actually, it would be Chemical Energy --> Kinetic Energy --> Potential Energy. As for the differences in change of temperatures, I just wrote that the rise in temperature per unit time isn't constant (non-linear), hence the change in temperature is less as time goes by.

    The acceleration part WAS supposed to be like that. On the other hand, for deceleration the word constant wasn't actually mentioned. It just said that the parachutist decelerated, which means they can't penalize you for how you shaped it because they haven't specified. Simply put, both a curve...

    Wait, what? Half-life is essentially the time taken for half of a substance to decay and if something has a half-life of 12 years, it means half of it decays in 12 years. Hence, if it starts with 40 million atoms, then after 12 years, it will have 20 million atoms. It doesn't matter if they give...

    The question told us to consult our graph, and the line intersected the x-axis at a point greater than 2. This means that that with a height of 2, d would've been 0 and the car would've stopped at position 2. That's the only thing that made sense tbh.

    Yup, that's exactly what I wrote.

    There are always plenty of options in questions related to apparatus so you could've written things like volume of liquid, thickness of test-tube walls, materials used to make apparatus, thermometers etc in the fourth question. On a side note, was the graph supposed to pass through the origin...
