Answer:
British laws and customs were introduced. Schools and hospitals were built. Britain has the largest variety of different cultures, this has made Britain the most diverse country because we took over many colonies and a lot have come to live in Britain.
Explanation:
Answer:
56.25 watts
Explanation:
P = F * d / t
P = Power (it's an unknown at this point).
F = 450 N
d = 25 steps each 10 cm = 25 steps 0.1 m/step = 2.5 m
t = 20 s
Solution
P = 450 * 2.5 / 20
P = 1125/20
P = 56.25
A diverging lens has a focal length of magnitude 21.8 cm and the images are located behind the lens.
(a) u = -10.9 cm
1/v= 1/10.9 - 1/21.9
v= 21.8cm
Behind the lens.
(b) 1. Virtual
2. Virtual
3. Real
(c) m = v/u
1. Erect/ Upright
2. Upright
3. Inverted
(d) m = v/u
1. m = -43.6/-43.6 = 1. Magnification = 1.
2. infinity.
3. m = 21.8 / -10.9 = -2. Magnification = -2.
Therefore, these are the answers for above given question.

Answer:
Explanation:
When unpolarized light passes through a polarizer, only the component of the light vibrating in the direction parallel to the axis of the polarizer passes through: therefore, the intensity of light is reduced by half, since only 1 out of 2 components passes through.
So, after the first polarizer, the intensity of light passing through is:
Where is the initial intensity of the unpolarized light.
Then, the light (which is now polarized) passes through the second polarizer. Here, the intensity of the light passing through the second polarizer is given by Malus Law:
where:
is the angle between the axes of the two polarizers
In this problem the angle is
So the intensity after of light the 2nd polarizer is:
Answer:
Distance = 22m
Displacement = 12 + 2 - 8 =6m
