    Yup. no matter the horizontal velocity. vertical component of velocity for both balls remains same. So time taken which is independent of mass i.e root(2gh) will be same for both balls. 🙂
    This is one the most basic principles of parabolic motion

    Does incoming solar radiation contain infrared radiation or is it just earth produced. What is the exact difference between long radiation and short radiation?

    Regarding Q2: how will both the spheres reach at the same time ? What if they have variability in masses (which is not given in the question).

    You must be familiar with an equation of motion
    S=ut+1/2(at^2)
    Where S= The distance traveled u= initial velocity t= time taken a=acceleration
    So in this case if yo apply this in vertical direction for both the spheres you would realize that acceleration is ‘g’ for both whereas u is zero for both (in vertical direction), Hence the time would be same.
    Hope it helps

    Got messed up with Hard water. Thought boilers would function fine.
    Took a guess in 1st and 3rd.
    In 3rd could eliminate 2 statements. Sugar level regulators and calcium level regulators (is there anything like that ? ). Took a guess between the renaming two.
    1st was purely by luck. I though laser light is in visible spectrum. Though still confused.
    Good questions team!

    While answering Q2, I was sure that its a gamble question and answer is definitely not Option C but still mark that option.

    Please some one explain why both the sphere will reach ground at same time!! Suppose one is made of feather and other is hard ball of iron, then also, will they reach at same time?

    Q.2 : Motion in a particular direction is due to driving force in that direction and the amazing thing about this is that as forces are vector they are independent of each other. This results that regardless of the existing motion.

    So, if you throw a stone freely or give it a horizontal force, they will land on the same time as the net driving force in the vertical direction bringing them down is the gravitational acceleration only ie “g”

    This is a basic concept and rule of kinematics

    Did silly mistakes in 6&7.

    for Q2. SInce its a free fall, the only force that will act is ‘g’ which is independent of the mass.
