A wave hits an object as shown. A vertical line with Medium 1 to the left and Medium 2 to the right. An arrow from the left reaches the line. An arrow starts from the same point on the line and goes right at a different angle. Which kind of wave interaction is shown?
Answers
Answer:
refraction
Explanation:
When the wave moves from medium 1 to medium 2, then the wave gets refracted. Then the correct option is C.
What is the wave?A wave is an energetic disturbance in a medium that doesn't include any net particle motion. Elastic deformation, a change in pressure, an electric or magnetic intensity, an electric potential, or a change in temperature are a few examples.
A wave is a dynamic disturbance of one or more variables that propagates in physics, geometry, and related sciences. When waves oscillate frequently around an equilibrium value at a certain frequency, they are said to be periodic.
The bending of waves as they go from one substance to another is known as wave refraction. It bends when the wave enters a new material because the wave's speed changes. The optical density or index of refraction of the material affects how light waves bend.
Thus, the correct option is C.

Una pelota de golf se suelta desde el reposo del techo de un edificio muy alto. Despreciando la resistencia del aire, calcule (a) la posicion y (b) la velocidad de la pelota despues de 1s, 2s y 3s.
Answers
Answer:
a) y = y₀ - 4.9, v = -9.8 m / s, b) y =y₀ - 19.6, v = - 19 m / s
c) y =y₀ - 44.1, v = - 29.4 m / s
Explanation:
To solve this exercise let us use the kinematic relations
y =y₀ + v₀ t - ½ g t²
v = v₀ - g t
They indicate that the body is released therefore the initial velocity is zero v₀ = 0
y = y₀ - ½ g t²
v = - gt
a) the position and velocity for t = 1s
y = y₀ - ½ 9.8 12
y = y₀ - 4.9
v = - 9.8 1
v = -9.8 m / s
the negative sign indicates that the velocity is directed downwards
b) t = 2 s
y =y₀ - ½ 9.8 2 2
y =y₀ - 19.6
v = - 9.8 2
v = - 19 m / s
c) t = 3 s
y = y₀ - ½ 9.8 3 2
y =y₀ - 44.1
v = - 9.8 3
v = - 29.4 m / s
Based from the flow chart, what can you generalize about the formation of typhoons? How do typhoons develop?
Answers
Answer: Warm water from the ocean is needed to develop typhoon
Pls Rate this as Brilliant Answer thank you :) keep on learning
Typhoons form when strong winds blow into warm areas of the ocean. These winds pick up moisture and rise, bringing colder air with them. This creates pressure, causing the winds to move quickly. The winds revolve or spin around a central point known as an eye.
What is typhoon ?A typhoon is a mature tropical cyclone that forms in the Northern Hemisphere between 180° and 100°E. The Northwestern Pacific Basin is the most active tropical cyclone basin on Earth, accounting for nearly one-third of the world's annual tropical cyclones.
The Philippines is just above the equator and faces the western Pacific, with little else to absorb storm energy before it reaches land. Storms are fueled by warm, tropical waters, which produce approximately 20 typhoons per year.
Hurricanes and typhoons can wreak havoc on coastlines and hundreds of miles inland. They can generate winds of up to 155 mph, as well as tornadoes and microbursts.
Thus, Typhoons form when strong winds blow into warm areas of the ocean.

Is there a difference in how a black shirt or a white shirt affects our exposure to us radiation?
Answers
But there is definitely a difference in heat. If you insist on wearing a black shirt and you want to avoid having a heat stroke then you should probably consider bringing water, maybe an extra shirt and sun screen if you have to be outside for more than 10-15 minutes.
Under the sun, the black shirt absorbs all wavelengths (more light). A white shirt reflects the visible light that hits it.
heat follows the same laws of conservation of light energy. This means light energy and heat cannot be created or destroyed. The light and heat has to go somewhere.
The light doesn’t cause the heat but they follow the same rules so instead of visually seeing the lack of light, you feel the heat energy that is being absorbed by your shirt.
you are exposed to the same amount of radiation wearing a black shirt as you are the white shirt. The difference is the “color” (because some people don’t consider black and white a color) and how light reacts to it.

A person records a bird call as an analog wave. The sound is then stored on a computer as a digital signal. When a person wants to listen to the bird call, it needs to be converted back into an analog wave. What is an advantage of storing the bird call as a digital?
Answers
Answer:
In analog technology, a wave is recorded or used in its original form. In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device. On a CD, the sampling rate is 44,000 samples per second. An analog recording is considered unlimited. Therefore, it can move to a higher and higher resolution without losing its original quality.

A 12 kg object speeds up from an initial velocity of 10 m/s north to a final velocity of 15 m/s north. Calculate the change in momentum
Answers
Answer:
60m/s
Explanation:
momentum = Mass × Velocity
Initial Momentum = 12 × 10
= 120
Final Momentum = 12×15
=180
Change in Momentum = 180 - 120
= 60m/s
Answer:
60Explanation:
formula for change in momentum = F =∆p/∆t
F∆t = ∆p
∆p = m(v - Vo)
∆p = 12(15-10)
=12(5)= 60
An experiment is designed to test what color of light will activate a photoelectric cell the best. The photocell is set in a circuit that "clicks" in response to current. The faster the current, the more clicks per minute. In this experiment, the number of clicks in one minute is recorded for each color of light shining on the photocell. To change the color of light, a different color of cellophane is placed over the same flashlight and the flashlight is then located a specific distance from the photocell.
Which of the following was not kept constant?
the color of the light after it has passed through the cellophane
the source of the original light
the distance of the light from the photocell
the test for photocell activation

someone help pls. Two students, Mia and Peter, leave school to meet at the local coffee shop. Peter decides to jog to the coffee shop, but also stops at a flower shop along the way. Mia decides to walk from school directly to the coffee shop. They arrive at the coffee shop at the same time, 30 minutes after they leave school.
Answers
Answer:
1) The distance further it takes Peter to arrive at the Coffee shop than Mia is 1.24 km
2) Mia's average speed is 6.00 km/hour
Peter's average speed is 8.48 km/hour
4) Mia's average velocity = Peter's average velocity = 6.00 km/hour
Explanation:
The given information from the diagram are;
The distance Peter jogs from school to the flower shop = 2.00 km
The distance Peter jogs from the Flower shop to the Coffee shop = 2.24 km.
The distance Mia walks from school directly to the Coffee shop = 3.00 km
The time it takes both Peter and Mia to arrive at the coffee shop = 30 minutes = 0.5 hour
1) The total distance Peter travels from school to the Coffee shop = 2.00 km + 2.24 km = 4.24 km
The distance Mia travels from school to the Coffee shop = 3.00 km
The distance further it takes Peter to arrive at the Coffee shop than Mia = 4.24 km - 3.00 km = 1.24 km
The distance further it takes Peter to arrive at the Coffee shop than Mia = 1.24 km
2) [tex]Average \ speed = \dfrac{Total \ distance \ traveled}{Total \ time \ taken \ in \ the \ journey}[/tex]
[tex]Therefore, \ Mia's \ average \ speed = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Mia's average speed = 6.00 km/hour
[tex]Peter's \ average \ speed = \dfrac{4.24 \ km}{0.5 \ hour}= 8.48 \ km/hour[/tex]
Peter's average speed = 8.48 km/hour
4) [tex]Average \ velocicty = \dfrac{Displacement }{Time \ taken}[/tex]
The displacement from the School to the Coffee shop is 3.00 km for both Mia and Peter
The time it takes both Peter and Mia to arrive at the Coffee shop from the school is 30 minutes = 0.5 hour
[tex]Therefore, \ Mia's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Mia's average velocity = 6.00 km/hour
[tex]Peter's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Therefore, Peter's average velocity is also = 6.00 km/hour
