Explanation:
Elephants can communicate using very low frequency sound waves over long distances. An elephant makes a noise below human hearing at 16Hz. This low rumble moves at 350 m/s (speed of sound in air). This sound is detected by her friend 25 seconds later.
How far away is her friend?
Answer:
8750 m
Explanation:
S= v x t
S= 350 x 25
S= 8750 m
The elephant's friend is 8750 meters away.
The subject of this question is Physics, specifically related to sound waves and their travel. The question involves an elephant communicating with infrasound at 16 Hz and determining the distance between it and the receiver of the sound by using the speed of sound in air. To answer how far away her friend is, you would use the equation of distance traveled by the wave, which is the product of the wave's speed and the time it took to reach the receiver.
Distance = Speed of Sound × Time
Distance = 350 m/s × 25 s
Distance = 8750 m

Light waves disperse in various planes through the lens.
Light waves refract in multiple directions through the lens.
Answer:
A) Light waves are restricted to a single plane through the lens.
Explanation:
Took the quiz and got it right
Final answer:
The view inside a lens differs from the outside because light waves refract in multiple directions within the lens, a process essential for lenses to form images by bending light.
Explanation:
The view within the rectangle lens is different than the view outside the lens because light waves refract in multiple directions through the lens. When light waves enter the lens, they experience refraction both when they enter and exit the lens medium. The concept of refraction is inherently three-dimensional and is based on the principle that when light passes through variations in matter, its direction changes due to the different speeds at which light travels in different media. This bending of light is essential for lenses to redirect light and form images, whether they are magnified, shrunk, or inverted.
Lenses like the eye's crystalline lens or a microscope's glass lens use refraction to form images by bending light towards or away from the line perpendicular to the boundary surface. The thin lens approximation simplifies this process by considering the double refraction through the lens as a single change in path occurring at the plane of the lens. An example of this principle in action would be rays of light entering a diverging lens and appearing to originate from its focal point due to their diverging paths.

How is photon energy calculated? (choose 2)
o Using Plank's constant.
o It cannot be calculated.
o Using the frequency.
Answer:
Explanation:
Based on the wave model of light, physicists predicted that increasing light amplitude would increase the kinetic energy of emitted photoelectrons, while increasing the frequency would increase measured current.
Contrary to the predictions, experiments showed that increasing the light frequency increased the kinetic energy of the photoelectrons, and increasing the light amplitude increased the current.
Based on these findings, Einstein proposed that light behaved like a stream of particles called photons with an energy of \text{E}=h\nuE=hνstart text, E, end text, equals, h, \nu.
The work function, \PhiΦ\Phi, is the minimum amount of energy required to induce photoemission of electrons from a metal surface, and the value of \PhiΦ\Phi depends on the metal.
The energy of the incident photon must be equal to the sum of the metal's work function and the photoelectron kinetic energy:

A ray in air hits the surface of water at 41.0 deg. At what angle does it travel in the water?
(Unit=deg)
Answer:
r = 29.53 degrees
Explanation:
Given that,
Angle of incidence, [tex]i=41^{\circ}[/tex]
We need to find the angle at which it will travel in the water. The refractive index of water is 1.33 and refractive index of air is 1. Using Snell's law as :
[tex]n_1\sin i=n_2\sin r[/tex]
r is the angle of refraction
[tex]\sin r=\dfrac{n_1}{n_2}\sin i\\\\\sin r=\dfrac{1}{1.33}\times \sin (41) \\\\r=\sin^{-1}(0.493)\\\\r=29.53^{\circ}[/tex]
So, the ray will travel at an angle of 29.53 degrees in the water.

Which of the following is an example in which kinetic energy is converted to potential energy?
O A. A rock falls down a cliff.
OB. A match burns.
OC. A spring is stretched.
OD. A light bulb glows brightly.
Answer:
C. A spring is stretched.
Explanation:
Kinetic energy is the energy of motion, potential energy is stored energy. The motion of stretching the spring is kinetic, the energy it has before it's released is potential.
When a spring is stretched, it stores potential energy.
Explanation:The correct answer is C. A spring is stretched. This is an example of kinetic energy being converted to potential energy because when a spring is stretched, it stores potential energy. Kinetic energy refers to the energy of an object due to its motion, while potential energy is the energy that an object possesses due to its position or state.
In this example, when a spring is compressed or stretched, work is done to change its shape. As a result, potential energy is stored in the spring. When the spring is released, the potential energy is converted back into kinetic energy as the spring returns to its original shape and moves.
This conversion between kinetic energy and potential energy is a fundamental concept in physics and can be observed in various everyday examples such as stretched springs, raised objects, or compressed gas.

the normal formula to find force is F = m* a. What kind of math do you need to do
to find the mass of an object?
Final answer:
The mass of an object can be found by rearranging the force equation F = ma to m = F/a and dividing the force by the acceleration. This requires basic algebraic manipulation. Using the units of newtons (N) for force and meters per second squared (m/s²) for acceleration will yield the mass in kilograms (kg).
Explanation:
To find the mass of an object using Newton's second law of motion, you would rearrange the typical force equation F = ma to solve for m. This rearranged formula becomes m = F/a. This mathematical operation requires basic algebra to isolate the variable m (mass). For example, if you know the force acting on an object and its acceleration, you just need to divide the force by the acceleration to obtain the mass. For instance, consider an object where a force of 22 Newtons causes an acceleration of 2.00 m/s², to calculate the mass you would simply perform the calculation m = F/a which becomes m = 22 N / 2.00 m/s² leading to m = 11 kg. It's important to use units of newtons for force, meters per second squared for acceleration, and the result will be in kilograms for mass.
When applying this to real-world problems, like determining the force on a wagon or calculating the normal force on an object, the process is the same. For forces in equilibrium, such as an object at rest on a surface, the normal force is often equal to the weight of the object, which can be calculated using F = mg, where g is the acceleration due to gravity.

9V Battery
1.5V AA Battery
9 V Battery has the least current than 1.5 V AA Battery.
Explanation:
A standard 9 V battery has about 400-600 mAh capacity. In the most basic terms, these batteries can supply about 500 milliamps for one hour before being "dead".
Normal AA/AAA batteries that have a voltage rating of 1.5 V can supply constant 50 mA current for a total capacity of 1800-2600 mAh.
Therefore 9 V Battery which have current around 400-600 mAh capacity has the least current than 1.5 V AA Battery which have 1800-2600 mAh capacity.
El gas encerrado en un recipiente con las paredes rigidas esta a una presion de 150 000 Pa. La temperatura del gas es de 27°C A que temperatura en Kelvin y grados Celcius hay que calentar el gas para que la presion sea 300 000 Pa???
Answer:
The gas enclosed in a container with rigid walls is at a pressure of 150,000 Pa. The temperature of the gas is 27 ° C. At what temperature in Kelvin and degrees Celcius does the gas have to be heated so that the pressure is 300,000 Pa?
Explanation:
Given that,
When the temperature is 27°C, it's pressure is 150,000 Pa
Then,
T₁ = 27°C
Let convert to Melvin
T₁ = 27 + 273 = 300K
P₁ = 150,000 Pa
What's the temperature when it is heated to a pressure of 300,000 Pa
T₂ =?
P₂ = 300,000 Pa
Since the gas is in a rigid wall container then the volume does not change so,
V₁ = V₂
Using Gay Lussac law,
P₁ / T₁ = P₂ / T₂
Making T₂ subject of formula
T₂ = P₂ × T₁ / P₁
T₂ = 300,000 × 300 / 150,000
T₂ = 600K
So, converting to °C
°C = K - 273
°C = 600 - 273
°C = 327 °C
Then, the final temperature at 300,000 Pa is 600K OR 327°C
So, using Spanish
Dado que,
Cuando la temperatura es de 27 ° C, su presión es de 150,000 Pa
Entonces,
T₁ = 27 ° C
Deje convertir a Melvin
T₁ = 27 + 273 = 300K
P₁ = 150,000 Pa
¿Cuál es la temperatura cuando se calienta a una presión de 300,000 Pa?
T₂ =?
P₂ = 300,000 Pa
Como el gas está en un contenedor de pared rígido, el volumen no cambia,
V₁ = V₂
Usando la ley Gay Lussac,
P₁ / T₁ = P₂ / T₂
Hacer T₂ sujeto de fórmula
T₂ = P₂ × T₁ / P₁
T₂ = 300,000 × 300 / 150,000
T₂ = 600K
Entonces, convirtiendo a ° C
° C = K - 273
° C = 600 - 273
° C = 327 ° C
Entonces, la temperatura final a 300,000 Pa es 600K o 327 ° C

A ball rolls horizontally off a bookshelf at a height of 1.7 m with a speed of 2 m/s then it takes 0.59 seconds. Hence, option B is correct.
What is acceleration?Acceleration is the rate at which the direction and speed of motion evolve over time. Anything was shown to be accelerated when it goes straighter and faster or slower. Motion on a circle therefore accelerates even though the speed is constant, so because direction is always changing. All those other types of movement experience an acceleration as a result of these factors.
It is a vector quantity because acceleration includes both a magnitude and a direction. The other vector quantity is velocity.
Use the equation of motion,
s = ut + 1/2 at²
1.7 = 2 (t) +1/2(-9.8)t²
t = 0.59 seconds.
Therefore, the time will be equal to 0.59 seconds. So option B is the correct one.

What is meant by motor oil ?Motor oil is a lubricant used in the moving parts of a engines, vehicles and other machines.
Engines have moving parts that rub against one another, wasting heat instead of kinetic energy that would otherwise be beneficial. Furthermore, it degrades those components, which can cause the engine to run less efficiently and become less reliable.
In addition to extending the life of engines, proper lubrication reduces fuel use and wasted power.
In order to prevent direct contact between surfaces of adjacent moving parts, lubricating oil forms a separating layer between them. This minimizes frictional heat generation and wear, safeguarding the engine. When in use, motor oil conducts heat as it moves through the engine. This heat is transported through airflow over the external surface of the oil pan, airflow through an oil cooler, and through oil gases expelled by the positive crankcase ventilation (PCV) system in an engine with a recirculating oil pump.
Peer-reviewed journals and books are regarded as the most dependable sources and are frequently a great resource for finding reliable and scientific content.

Answer:
a) v₂ = 8,112 m / s , b) P₂ = 206.8 10³ Pa
Explanation:
This is a fluid mechanics exercise, let's use index 1 for thick pipe and index 2 for thinner pipe
a) with the continuity equation it allows to find the speed of the water
v₁ A₁ = v₂ A₂
the area of a circle is
A₁ = π r₁² = π d₁² / 4
v₂ = v₁ d₁² / d₂²
