Answer:
sry abt cuz I don't know the answer
have a great day
Answer:
Sry but the question is not visible.......so plzz attach another image
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:
Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
Explanation:
Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession
Answer:
12.17 m/s²
Explanation:
The formula of period of a simple pendulum is given as,
T = 2π√(L/g)........................ Equation 1
Where T = period of the simple pendulum, L = length of the simple pendulum, g = acceleration due to gravity of the planet. π = pie
making g the subject of the equation,
g = 4π²L/T²................... Equation 2
Given: T = 1.8 s, l = 1.00 m
Constant: π = 3.14
Substitute into equation 2
g = (4×3.14²×1)/1.8²
g = 12.17 m/s²
Hence the acceleration due to gravity of the planet = 12.17 m/s²
