VIL. Long answer questions 1. Calculate the number of water molecule present in one drop of water which weighs 0.188 2 NH2 NH (The atomic mass of nitrogen is 14, and that of hydrogen is 1) I mole of nitrogen 3 moles of hydrogen 8) + 8) 2 moles of ammonia

and 1and 1

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
