Which has more number of atoms, 100 grams of sodium or 100 grams of iron (given, atomic mass of Na = 23 u, Fe = 56 u)?
100 gm of sodium will have (Given mass / molar mass )x Avogadro's Number = (100/23) x 6.022 x 10^23 = 2.62 x 10^24 atoms 100 gms of Iron will have (100/56) x 6.022 x 10^23 = 1.07 x 10^24 atoms So 100 gms of Sodium will have more atoms.

Helium atom has an atomic mass of 4u and two protons in its nucleus. How many neutrons does it have?
Mass number of Helium = 4 Number of protons = 2 Number of neutrons(n) = Number of Mass(A) — Number of proton (P) = 4 – 2 = 2 Thus, No. of neutrons = 2

Why when a ball dropped from a height, its speed continuously increased?
the potential energy gets converted into kinetic energy so obviously yes. as velocity is the only variable , as the height decreases, there should be a corresponding increase in the velocity. (potential energy = mgh, kinetic energy = 1/2 mvxv
