Answer:
λ = 547.96 nm
Explanation:
given,
thickness of soap bubble = 103 nm
refractive index of thin film = 1.33
using formula of constructive interference
t is thickness of the medium
n is refractive index
m = 0,1,2...
now,
at m = 0
λ = 547.96 nm
at m = 1
λ = 182.65 nm
the only visible light enhanced by the thin film is of wavelength
λ = 547.96 nm
It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.
I hope this helped :)
Answer:
Explanation:
The first equation of motion given as,
v = u +at
Here, u is initial and v is final velocity and a is acceleration and t is time taken.
As per question car initial velocity, u = 90 m/s, final velocity, v =0 and time taken, t = 3.00 s.
Substituting these values in first equation of motion, we get
0 = 90 m/s + a×3.00 s
or,
Thus, the deacceleration of the car is
Answer:
98 m √
Explanation:
How about s = Vo * t + ½at² ?
s = h = Vo * 2s - 4.9m/s² * (2s)² = 2Vo - 19.6
and
h = Vo * 10s - 4.9m/s² * (10s)² = 10Vo - 490
Subtract 2nd from first:
0 = -8Vo + 470.4
Vo = 58.8 m/s
h = 58.8m/s * 2s - 4.9m/s² * (2s)² = 98 m
Answer:
a) Both have same angular speed
b) Mary has larger linear speed
c) Mary has larger radial acceleration
Explanation:
a) Since Tom and Mary are both on the same merry-go-around, all points on the merry-go-around are subjected to a same angular speed. Therefore, they both have the same angular speed.
b) Linear speed, however, is the product of angular speed and their radius or rotation, aka their distance the the center of rotation. In this case Mary has a larger radius since she's sitting at the outer rim.
c) Radical acceleration is the product of angular speed squared and their radius so again, Mary would have a larger radial acceleration because of greater radius.
