Answer:
The distance between the slits is given by 1.3 × m
Given:
D = 4 m
y =
m = 1
To find:
distance between slits, d = ?
Formula used:
y =
y = distance of first bright band from central maxima
D = distance between screen and source
d = distance between slits
= wavelength
Solution:
distance of first bright band from central maxima is given by,
y =
y = distance of first bright band from central maxima
D = distance between screen and source
d = distance between slits
= wavelength
Thus,
d =
d =
d = 1.28 ×
d = 1.3 × m
The distance between the slits is given by 1.3 × m
a.
The equivalent resistance of a series combination of two resistors is equal to the sum of the individual resistances:
In this circuit, we have
Therefore, the equivalent resistance is
b. 5.8 V, 3.2 V
First of all, we need to determine the current flowing through each resistor, which is given by Ohm's law:
where V = 9.00 V and . Substituting,
Now we can calculate the potential difference across each resistor by using Ohm's law again:
