Considering the unknown resistence as R and using the Ohm's First Law, we have:
The equivalent resistence is given by the resistor series with the lamp resistence.

Answer: one atmosphere!
Explanation: The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr). I hope this answers your questionl.
Answer:
Force will increase 3 times
Explanation:
We know force is directly porpotional to acclereation, with the constant, m mass.
So if we mass is increased 3 times the force will increase 3 times.
Answer:
= 625 nm
Explanation:
We now that for
for maximum intensity(bright fringe) d sinθ=nλ n=0,1,2,....
d= distance between the slits, λ= wavelength of incident ray
for small θ, sinθ≈tanθ= y/D where y is the distance on screen and D is the distance b/w screen and slits.
Given
d=1.19 mm, y=4.97 cm, and, n=10, D=9.47 m
applying formula
λ= (d*y)/(D*n)
putting values we get
on solving we get
= 625 nm
