Recently, We've been discussing this specific topic in my RS class. So, there are many theories to explain the existence of the world such as the Big Bang, Evolution or the Creation story.
Although these are three different ideas, they can still be related or interconnected with one another in some way. For example, George Lemaintre's Big Bang explanation can be linked with the Creation story in ways such as God being present at the Big Bang or even God being the one to allow the Big Bang occur.
Furthermore, God might have created us as apes or monkeys then we evolved to become humans.
In conclusion, the universe couldn't have come to pass just like that, they're must be Scientific or Theological truths to back this up. The only thing is that people have their unique beliefs, according to their religion, culture and childhood background.
To solve this problem it is necessary to apply the concepts related to Malus' law. Malus' law indicates that the intensity of a linearly polarized ray of light that passes through a perfect analyzer with a vertical optical axis is equivalent to:

Indicates the intensity of the light before passing through the Polarizer,
I = The resulting intensity, and
= Indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
There is 3 polarizer, then
For the exit of the first polarizer we have that the intensity is,

For the third polarizer then we have,

Replacing with the first equation,



Therefore the transmitted intensity now is
of the initial intensity.
Answer:
Net force = 250 N
Explanation:
Given that,
The mass of a teacher, m = 75 kg
As the parachute opens, the system experiences a 1000N drag.
We need to find the magnitude of net force acting on the teacher. 2 forces are acting on her i.e. drag force and weight.
Net force,
F = mg-D
= 75(10)-1000
= -250 N
Hence, the net force is 250 N and it is acting in the upward direction.
Answer:
The velocity of the man is 0.144 m/s
Explanation:
This is a case of conservation of momentum.
The momentum of the moving ball before it was caught must equal the momentum of the man and the ball after he catches the ball.
Mass of ball = 0.65 kg
Mass of the man = 54 kg
Velocity of the ball = 12.1 m/s
Before collision, momentum of the ball = mass x velocity
= 0.65 x 12.1 = 7.865 kg-m/s
After collision the momentum of the man and ball system is
(0.65 + 54)Vf = 54.65Vf
Where Vf is their final common velocity.
Equating the initial and final momentum,
7.865 = 54.65Vf
Vf = 7.865/54.65 = 0.144 m/s
