Answer:
Explanation:
Formula to calculate the distance between two points and
is,
d =
Therefore, length of CD having coordinates C(3,1) and D(3, 3),
CD =
= 2 units
Formula to find the midpoint of CD is,
M =
=
= (3, 2)
Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.
Kirchhoff's loop rule is also referred to as Kirchhoff's second law or Kirchhoff's voltage law, and it states that the algebraic sum of all the electric potential differences around any closed loop is equal to zero.
<h3>How to connect two runs in series?</h3>Since the chairlifts are analogous to batteries, and the runs are analogous to resistors, the two runs would represent resistors that are connected in series with the lift, which represents the battery. Similarly, these three runs can also be connected in parallel by altering the positions of the runs with the battery.
For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

Answer:
ν = 5.45 x 10¹⁴ Hz
Explanation:
given,
wavelength of light = 550 nm
= 550 x 10⁻⁹ m
speed of light = 1.96 x 10⁸ m/s
speed of sound = 3 x 10⁸ m/s
frequency of the light = ?
we know.
frequency of the light in the liquid is same as the frequency of the light in the air.
ν is the frequency of light
ν = 5.45 x 10¹⁴ Hz
Hence, the frequency of light in the liquid is equal to ν = 5.45 x 10¹⁴ Hz
