Answer:
The pattern would spread out.
Explanation:
The fringe width is given by the relation
fringe width = λ L / D where λ is wavelength of light used, L is distance of wall from the source of light and D is slit separation.
If we increase λ , fringe width will increase and therefore pattern will spread out .
Density is equal to mass divided by volume; that said, you would divide 38.6 by 2 to get your answer
Answer:
579600J
Explanation:
Given parameters:
Height of the building = 828m
Weight of the man = 700N
Unknown:
Work done by the man = ?
Solution:
The work done by the man is the same as the potential energy expended.
Work done:
Work done = Weight x height = 700 x 828
Work done = 579600J
It could help transport important information
Answer:
14.5 hours
Explanation:
The relationship between speed, time and distance for a uniform motion is
where
v is the speed
d is the distance
t is the time taken
Here we know:
v = 24.0 m/s is the average speed
is the distance
Solving the equation, we find the time taken:
And since
1 hour = 3600 s
The time in hours is
