Energy, in any form, is a scalar quantity. Hence, potential energy is also a scalar quantity..

Work is scalar , so energy is scalar
Comments

energy in any form is always a scalar quantity,since it has only magnitude never direction.so potential energy is also a form of scalar quantity.

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
