Answer:
θ = 66.90°
Explanation:
we know that
I= intensity of polarized light =1
I_o= intensity of unpolarized light = 13
putting vales we get
⇒
therefore θ = 66.90°
2,992² + r² = ( r + 180 )²
8,952,064 + r² = r² + 360 r + 32,400
360 r = 8,952,064 - 32,400
360 r = 8,919,664
r = 8,919,664 : 360
r = 24,776.844 km
d = 24,776.844 · 2 = 49,553688 ≈ 49,554 km
Answer:
The approximate diameter of the planet Neptune is 49,554 km.
The component of the total velocity in the x - direction is 6.96 m/s.
The component of the total velocity in the y - direction is 2.95 m/s.
<h3>
Component of the velocity in x direction </h3>
The component of the total velocity in the x - direction is calculated as follows;
v(x) = vtot cosθ
where;
- vtot is total velocity
- v(x) is velocity in x direction
v(x) = 7.56 x cos(23)
v(x) = 6.96 m/s
<h3>
Component of the velocity in y - direction</h3>
v(y) = vtot sinθ
v(y) = 7.56 x sin(23)
v(y) = 2.95 m/s

Mass does not change anywhere in the space .
So the given 30N is equal to the product of mass of the body and the acceleration due to gravity at that place in space.
After finding the mass of the body multiply it by the given acceleration due to gravity.
Mg is the approximate force due to gravity between the mass and the planet.
