Question

P=abled
The percentage errors of measurement in a, b, c and d are 1%, 3%,
respectively. What is the percentage error in the quantity P? If the value of
using the above relation turns out to be 3.763, to what value should y
the result?
14 A book with many printing errors contains four different formulas for the
y of a particle undergoing a certain periodic motion :
(a) y = a sin 21 t/T
(b) y = a sin vt
(c) y = (a/T) sin t/a
(d) y = (a/2) (sin 21t/T + cos 2nt/T)
(a = maximum displacement of the particle, v= speed of the particle. T
of motion). Rule out the wrong formulas on dimensional grounds.
15 A famous relation in physics relates 'moving mass' m to the rest
particle in terms of its speed v and the speed of light, c. (This relation
a consequence of special relativity
