Answer: In double slit case, you need to understand superposition on waves emerging from dirrerent slit.
Explanation: When passing a single slit, wave spread in all directions.
In double slit waves with equal wavelength travel different path and distance
trey travel is different . Waves meet each other in different positions in different phases. If phase are same, waves have contructive interference, crests of waves meet in same point. Amplitudes of waves are added together. If waves are in opposite phases, sum of amplitudes
ame subtacted and this is destructive interference. Sum of amplitudes are zero.
It was Hooke who formed his ideas about living things by performing observations without using a microscope, but it should be noted there were others as well.
Answer:
A
Explanation:
all the work is in the attached file :D
In order to answer this exercise you need to use the formulas
S = Vo*t + (1/2)*a*t^2
Vf = Vo + at
The data will be given as
Vf = final velocity = ?
Vo = initial velocity = 1.4 m/s
a = acceleration = 0.20 m/s^2
s = displacement = 100m
And now you do the following:
100 = 1.4t + (1/2)*0.2*t^2
t = 25.388s
and
Vf = 1.4 + 0.2(25.388)
Vf = 6.5 m/s
So the answer you are looking for is 6.5 m/s
