Answer:
the two pink/purple in the first box with the green ones and blue and grey in the second box
a. θ = 41. 4°
b. θ = 60°
c. θ = 75. 5°
d. θ = 90°
<h3>How to determine the angle</h3>
From the given information, we would be using the Malus' law
It is given as;
I = I0 cos²θ
Where I0 is the intensity of the polarized light after passing through P
a. To find the angle, compare with the given equation
I = (0.750)I0
I = I0 cos θ
then
cos θ = 0. 750
θ =
θ = 41. 4°
b. I = (0.500)I0
cos θ = 0. 500
θ =
θ = 60°
c. I = (0.250)I0
cos θ = 0. 250
θ =
θ = 75. 5°
d. I = 0
cos θ = 0
θ =
θ = 90°

Answer:
a) 431 Hz
b) 429 Hz
c) 403 Hz
Explanation:
The frequency you heard is calculated using the relation
f = f(s) / [1 - (v(s)/v) ]
f = 400 / [1 - 25/343]
f = 400 / (1 - 0.0729)
f = 400 / 0.9271
f = 431.5 Hz
The frequency your friend starts hearing is
f = f(s) * [1 + (v(s)/v) ]
f = 400 * [1 + 25/343]
f = 400 * (1 + 0.0729)
f = 400 * 1.0729
f = 429.2 Hz
when you're next to each other and you are hearing 3 beats per second. The frequency you're singing is 400 + 3 Hz
403 Hz

Hey There!</h2><h2>

Answer:</h2>
<h2>_____________________________________</h2><h3>DATA:</h3>
Radius of Mercury = =
Mass of Mercury =
Distance Satellite above the surface of the Mercury = d = 265,000m
Gravitational Constant =
<h2>_____________________________________</h2><h3>SOLUTION:</h3>
Since the Satellite is orbiting around the Planet Mercury, due to the centripetal force, and Centripetal force is the force that acts towards the center of the circle, Whereas The gravitational force also acts towards the center of the circle thus we can say that Centripetal force is equal or same as centripetal force. So,
Fg is Given by,
Fc is Given by,
Where,
G is Gravitational Constant
is mass of Planet Mercury
is Mass of Satellite
r(small letter) is the distance between the center of the Planet Mercury and the satellite.
V is velocity of satellite
<h2>_____________________________________</h2>
Now,
r can also be written as,
Substitute the variables,
Simplify the equation,
V = 2814
Approximately,
V = 2800

I hope I can help! :)
A concave mirror is when the object is anywhere from infinity to focus the image so form will be real and inverted.
And when the object is between pole and focus of concave mirror then image so formed will be virtual and erect and the size of image is greater than size of object.
So, the answer would be "where light rays disperse."
Have a great day/evening/night! :)
Let me know if you have any additional questions!
