C. Amplitude: 60 cm; wavelength: 60cm
D. Amplitude: 60cm; wavelength 110cm
Answers
Choice-B is correct, but only halfway. This weird drawing appears to show TWO waves travelling through the same medium.
-- The big wavy line is a transverse wave, with amplitude=30cm and wavelength=110cm.
-- The short vertical lines are placed where the medium is squished, with thin spread out regions between them. This is a longitudinal wave, with amplitude=5cm and wavelength=10cm.
This could be the picture of a sound wave zipping along through the top of a train of 30cm waves on the lake.

what happens when light travels from one medium to another with a different index of refraction at a 0 degree angle of incidence?
Answers
Answer: light will travel in a straight line undeviated. Thus, there will be no refraction.
Explanation:
If the light hits the interface at angle equal to zero, then light movement is perpendicular to the plane of the second medium. And it will pass through undeviated. Therefore, the angle of refraction will also equal to zero. That is, there is no refraction.
Final answer:
Light entering a new medium at a 0 degree angle of incidence changes speed due to refraction but continues in a straight direction, and if it reflects, a 180° phase change occurs.
Explanation:
When light travels from one medium to another with a different index of refraction at an angle of incidence of 0 degrees, the light enters the new medium without changing its direction. This phenomenon is based on the principles of refraction, although at 0 degrees, the refraction is not visually evident since the light continues in a straight path. However, the speed of the light changes as it moves into the medium with a different refractive index. Moreover, if the light reflects from a medium with an index of refraction greater than that of the medium it is traveling from, a 180° phase change or a (lambda/2) shift occurs.
which two things affect how a lens refracts light
Answers
Answer:
The focal length, however, is a direct consequence of how much that lens refracts light, which (at least mostly) depends on two things: the index of refraction of that glass/plastic/whatever in the lens, and the curvature of the lens surfaces.
Explanation:
Final answer:
Understanding how lenses refract light involves considering the indices of refraction and the interaction with different mediums.
Explanation:
Lenses refract light based on two main factors: the indices of refraction of the lens material and the medium it interacts with. For example, when light enters a lens material with a higher refractive index, it bends towards the perpendicular, causing refraction.

-Brian has earwax build up
Final answer:
The doctor's likely diagnoses include harmful noise exposure for Brody leading to tinnitus, age-related hearing loss for Ashley, bacterial ear infections for swimmer Keaton, and earwax buildup for Brian due to improper ear cleaning methods.
Explanation:
The most likely diagnoses for each patient described based on their symptoms are as follows: Brody was exposed to harmful noise at the concert, which could have led to temporary or permanent hearing damage such as tinnitus. Ashley, having been born in 1934, is likely experiencing age-related hearing loss, also known as presbycusis, which often involves difficulty hearing higher-pitched sounds. Keaton, a swimmer who suffers from frequent ear infections, likely has bacteria in the ear causing conductive hearing loss. Brian, who frequently cleans his ears with a cotton swab and experiences muffled sounds, is likely suffering from earwax buildup that is impeding sound transmission.
A satellite orbiting Earth at an orbital radius r has a velocity v. Which represents the velocity if the satellite is moved to an orbital radius of 5r?
A.15√v
B.15v
C.5√v
D.5v
A. IS THE CORRECT ANSWER!
Answers
Answer:
The correct answer is V√5
Explanation:
Let V be the velocity of the satellite orbiting at radius r.
Let V(5r) be the velocity of the satellite orbiting at radius 5r.
Recall:
Escape velocity is given by:
V = √(2gr)
Where V is the escape velocity
g is the acceleration due to gravity
r is the radius of the earth.
With the above equation, we can obtain the answer to the question as follow:
V = √(2gr)
V(5r) = √(2g5r)
Next, we'll obtained the ratio of V(5r) to V as shown below
V(5r) : V => V(5r)/V
V(5r)/V = √(2g5r) / √(2gr)
V(5r)/V = √5
Cross multiply
V(5r) = V√5
From the above illustration, we can see that when the satellite is moved to 3r, then the expression for the velocity will be V√5

D.)needs fewer electrons to gain enough nuclear binding forces to overcome

Answers
Answer:
Option A needs more neutrons to gain enough nuclear binding forces to overcome the repulsion.Hope this answer helps.
Final answer:
As the number of protons in a nucleus increases, the nucleus requires more neutrons to stabilize the increased electrostatic repulsion between protons by increasing the nuclear binding force.
Explanation:
When an atom's nucleus gets larger with more protons, the electric charges repelling these protons also increase. To help stabilize the nucleus against this repulsion, it needs additional neutrons, which do not carry any electric charge, and provide additional nuclear binding forces to balance out the electrostatic repulsion between protons. The strong nuclear force between neutrons and protons is crucial to keep the nucleus intact, and it is stronger and shorter-ranged than the Coulomb force (electrostatic force) that causes repulsion between the positively charged protons.
Therefore, to compensate for the greater electric charge and maintain nuclear stability, an atom requires more neutrons, which adds to the nuclear binding force. This is most relevant for heavy nuclei, where neutrons greatly outnumber protons, to keep the repulsive forces at bay and the nucleus stable. For example, in heavier elements, stable isotopes typically have a greater number of neutrons than protons due to this requirement for a balanced nuclear force. In summary, the correct answer is:
A.) needs more neutrons to gain enough nuclear binding forces to overcome the repulsion.

Fire investigators begin their search with the point of origin, which is the location where the fire started. This helps them determine the cause of the fire and they can do this by examining damage patterns and looking for ignition sources.
Explanation:In the process of investigating a fire, fire investigators typically begin their search with the point of origin. The point of origin is the location where the fire started. It is the most critical area in any fire investigation as it helps in determining the cause of the fire. Locating the point of origin involves carefully examining the fire scene, observing patterns of fire damage, and often working backwards from the areas of least damage towards the areas of most damage. Once the point of origin has been located, the investigators then look for sources of ignition, fuels, and any potential accelerants that may have contributed to the spread of the fire.

Two questions. 10 points.
With the same force applied, which of these will have a greater acceleration?
F.100g mass
G.200g mass
H.300g mass
J.All the objects would have the same acceleration.
A 22.4kg object is accelerating at 1.40m/s2. What net force is being applied to the object?
A 16.0 N
B 21.0 N
c 23.8 N
D 31.4 N
Answers
From Newton's Second Law of Motion, acceleration is given by this formula:
[tex]Accelertaion = \frac{Force}{Mass}[/tex]
From the above formula, we can deduce that acceleration is inversely proportional to the mass of an object. Thus, the smaller the mass of an object, the greater would be its acceleration when the same force applied.
Therefore, the 100 gram mass will have a greater acceleration with the same force applied.
Question 2.
Given the following data:
Mass = 22.4 kg.Acceleration = 1.40 [tex]m/s^2[/tex].Mathematically, net force is given by this formula;
[tex]Net\;force = mass \times acceleration[/tex]
Substituting the given parameters into the formula, we have;
[tex]Net\;force = 22.4 \times 1.40[/tex]
Net force = 31.4 Newton.
Read more on force here: brainly.com/question/1121817
Final answer:
The 100g mass will have the greatest acceleration when the same force is applied, due to Newton's second law of motion. For the second part, the net force being applied to a 22.4kg object accelerating at 1.40m/s^2 is closest to 31.4 N.
Explanation:
The first part of the question asks: With the same force applied, which of these will have a greater acceleration? The options are 100g mass, 200g mass, 300g mass, and all objects having the same acceleration. According to Newton's second law of motion, acceleration is inversely proportional to mass when the force applied is constant. Therefore, the 100g mass will have the greatest acceleration (option F).
For the second question, a 22.4kg object is accelerating at 1.40m/s2. To find the net force being applied to the object, we use the formula F = ma, where F is the force, m is the mass, and a is the acceleration. Plugging in the values, we get F = 22.4kg * 1.40m/s2 = 31.36 N.
Therefore, the closest answer is option D, 31.4 N.

What is speed?
The rate at which an object's location varies over time is depicted by the slope of a linear position-time graph. The slope in the case of linear motion is the same as the object's speed. It offers details about the object's velocity, or how swiftly it is going.
On the other hand, acceleration describes the rate at which velocity changes. It is not directly connected to a position-time graph's slope. A velocity-time graph can be used to calculate acceleration by dividing the velocity change by the time change to get the slope of the graph.
