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:
Geothermal
Explanation:
Geothermal is obtained from the heat from the ground which makes it friendly
A child slides down a hill on a toboggan with acceleration of 1.8 m/s2. if she starts from rest, how far has she traveled in: 2 seconds
Answer:
2.4 m
Explanation:
From the question above,
Applying equation of motion,
s = ut+at²/2....................... Equation 1
Where t = time, u = initial velocity, a = acceleration, s = distance.
make s the subject of the equation,
Given: a = 1.8 m/s², t = 2 seconds, u = 0 m/s (from rest)
Substitute these value into equation 1
s = 0(2)+1.8(2²)/2
s = 1.2(4)/2
s = 2.4 m.
Hence she has traveled 2.4 m
Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. ... The moon appears full when the Earth is between the moon and the sun
Answer:
-3.63 degree Celsius
Explanation:
We are given that
Boiling point of solution=
C
Boiling point water=100 degree Celsius



Where
=Boiling point of solution
Boiling point of pure solvent
C

Using the formula

Molality,
m

Using the formula


We know that

Where
=Freezing point of solvent
Freezing point of solution
Using the formula

Freezing point of water=0 degree Celsius

Hence, the freezing point of solution=-3.63 degree Celsius
