Answer:
wavelength 
= 437.27 nm
Explanation:
given data
first bright fringe = 2.96 mm
slit separation = 0.325 mm
distance D = 2.20 m
solution
we know that this is double slit experiment
so we apply here Fringe width formula that is
β = 
....................1
is Wavelength of light and D is Distance between screen and slit and d is slit width
so put here value and we get
= 
= 437.27 × 
m
wavelength = 437.27 nm
Answer:
331.7m/s
Explanation:
Given parameters:
Initial velocity = 100m/s
Acceleration = 50m/s²
Distance = 1km = 1000m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we have to apply the right motion equation shown below;
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
Now insert the parameters and solve;
v² = 100² + (2 x 50 x 1000)
v² = 110000
v = √110000 = 331.7m/s
(if you have Q1: Carbon is found in: living animals and plants, oceans, rocks, atmosphere, and fossil fuels)
Q2: Humans are burning carbon and putting it into the atmosphere.
Q3: True
Q4: While carbon dioxide is in the air waiting to be reabsorbed it traps the sun's heat.
(and if you have Q5: In the last 250 years, the amount of carbon in the air has increased by 40 percent.)
