Answer:
x = 3 cm
Explanation:
Given that,
The separation between the slits,
The distance from the slits to a screen, D = 2.5 m
Let x is the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits,
We know that the bright fringe is given by :
So, the spacing between the first-order and second-order bright fringes is :
x = 0.03 m
or
x = 3 cm
So, the spacing between the first-order and second-order bright fringes is 3 cm. Hence, this is the required solution.
Answer:
18
Explanation:
we need the to know the extra weight Eric has over Tom. To do that we need to subtract Tom's weight from Eric's, but now we do not know what Eric's weight is or Tom's weight. the only clue we have is that Eric is 4 inches taller than Tom
1. if Eric is 4 inches taller that Tom, then
let
Tom's height be
and
Eric's height will be 4 inches more
let's plug these two information into the formula given in the question
for the difference in their weight;
Eric's weight will be;
w =
Tom's weight will be
w =
taking the difference between the two expressions above
w =
opening the bracket
w =
w = 18 pounds
so Eric's weight is 18 pounds more than Tom's
Answer:
The distance is
Explanation:
From the question we are told that
The distance of separation is
The wavelength is
The distance of the screen is
Generally the distance of a fringe from the central maxima is mathematically represented as
For the first dark fringe m = 0
For the second dark fringe m = 1
So the distance from the first dark fringe on one side of the central maximum to the second dark fringe on the other side is
The answer is B. Mohammed has less kinetic energy than Autumn. Why cuz its right.
