Physics is a type of science, like life science.
Thank you for posting your question here at brainly. Below is Yoland's study:
<span>Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.
</span>
I think the answer is "She can use constructive interference to generate a wave with an amplitude of 1.5 m."
Answer: its The ability to do work or cause change. Energy of an object due to its motion.
Explanation:In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
Answer:
50.09 km/h
Explanation:
Given that an airplane flying due north at 90 km/h is being blown due west. The planes total velocity is 103 km/ hr north west.
What is velocity of the wind ?
The wind velocity can be calculated by using pythagorean theorem.
From the question,
Resultant Velocity R = 103 km/h
Plane velocity P = 90 km/h
Wind velocity W = ?
W^2 = R^2 - P^2
Substitutes all the parameters into the formula
W^2 = 103^2 - 90^2
W^2 = 10609 - 8100
W^2 = 2509
W = sqrt ( 2509 )
W = 50.09 km/h
Therefore, the velocity of the wind is 50.09 km/h
Answer:
<em>The angle between the transmission axes of the filters is</em> <em>65°</em>
Explanation:
The complete question is
Unpolarized light is incident upon two ideal polarizing filters that do not have their transmission axes aligned. If 18% of the light passes through this combination, what is the angle between the transmission axes of the two filters.
From Malus law,
....1
where is the intensity of the polarized light,
is the intensity of the incident light
β the angle between the transmission axes of the two filters
Since the intensity is reduced to 18% or 0.18 of its initial value, this means that
= 0.18
substituting into the equation above, we have
....2
equating the two equations, we have
=
= = 0.18
= = 0.424
= = 64.9 ≅ <em>65°</em>
