Answer:
The angle between the electric field and the axis of the filter is 54⁰
Explanation:
Apply the equation for intensity of light through a polarizer.
where;
I is the intensity of the transmitted light
I₀ is the intensity of the incident light
θ is the incident angle
If only 35 % of the intensity of a polarized light wave passes through a polarizing filter, then the ratio of the intensity of the transmitted light to that of the intensity of the incident light is given by;
Therefore, the angle between the electric field and the axis of the filter is 54⁰
It is a chemical change. I always think of a chemical/physical change as if you could reverse it back as it started off, for example if you stepped on a can you can reverse the can back probably not exactly like it was before but you can still reverse it so this would be a physical change, and if you baked a pizza you could not reverse the dough and everything else back.
The sound waves would not exsist in space because they is no sound in space
Answer:
0.125m/s^2
Explanation:
20-10=10
10 divided by 80=0.125m/s^2
We are
given that:
m = 5.5 kg
d = 12 m
t = 1.75 s
Using the
distance formula, we can get the acceleration of the ball:
d = (1/2) a*t^2
Rearranging:
a = 2d/t^2
= 2*(12 m)/(1.75 s)^2
a = 7.837
m/s^2

Newton’s 2nd law, force is defines as:</span>
F = ma
F = 5.5 kg
(7.837 m/s^2)
