Explain why sounds are fainter at high mountains than sea level
A mass of 3.6 kg oscillates on a horizontal spring with a spring constant of 160 N/m. When the mass passes the equilibrium point its speed is 5.2 m/s. d. What is the maximum displacement of the mass?
Answer:
x = 0.78 m = 78 cm
Explanation:
Applying the law of conservation of energy to the spring-mass system, we can write the following equation:
[tex]Kinetic\ Energy\ at\ Mean\ Position= Potential\ Energy\ at\ extreme\ position\\\frac{1}{2}mv^2 = \frac{1}{2}kx^2\\\\x^2 = \frac{mv^2}{k}\\\\x = \sqrt{\frac{mv^2}{k} }[/tex]
where,
x = maximum displacement = ?
m = mass = 3.6 kg
v = speed at mean position = 5.2 m/s
k = spring constant = 160 N/m
Therefore,
[tex]x = \sqrt{\frac{(3.6\ kg)(5.2\ m/s)^2}{160\ N/m} }\\\\[/tex]
x = 0.78 m = 78 cm
Sound and light are both found as _____, with a variety of ____. The sun, a source of light waves specifically, releases a type of _____. It can be found as UVA or UVB types. These lights give off different levels of _____, some of wich can be harmful. The word bank is Electromagnetic energy Waves Wavelength Radiation Ultraviolet light
Answer:
Waves; wavelength; electromagnetic energy; ultraviolet light.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases.
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Hence, sound and light are both found as waves, with a variety of wavelength. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of wich can be harmful.
Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB and UVC.
Following are the response to the fill in the blanks:
Sound is a mechanical wave that is strongly dependent on material for development and conveyance. It moves faster through solids instead of through liquids or gases. The light wave is electromagnetic radiation that does not require a medium of propagation to pass through a void of space in which no particles exist. Both 'sound and light' can be found as waves having varying wavelengths. Light waves, in particular, emit a form of radiant waves, which is available in UVA and UVB varieties. The lights emit varying degrees of UV light, many of which are dangerous. In addition, the UV spectrum is classified into three categories: UVA, UVB, and UVC.Therefore, the answer is "Waves, wavelength, electromagnetic energy, ultraviolet light".

Work out the area of a rectangle with base, b=20mm and perimeter, p=50mm
Answer:
100mm²
Explanation:
the other side: (50 - 20 × 2) ÷ 2 = 5
5 × 20 = 100
Answer:
Subtract given lengths: 50 - 20 = 30
Divide by 2 since there are 2 missing sides that need a length: 30 divided by 2 = 15
With the given side lengths multiply all of them to get your area.
15 x 20 = 300 is your area I am pretty sure.

Which describes the greenhouse effect? 1. Earth continues to get warmer over time because it is slowly moving closer to the sun. 2. Earth's atmosphere blocks the sun's ultraviolet light. 3. Pollution gets into the air, causing trees to not get enough oxygen. 4. Energy given off by earth is reflected off of earth's atmosphere back down to the surface.
Answer: The green house effect is best described by option 4 (Energy given off by earth is reflected off of earth's atmosphere back down to the surface).
Explanation:
The green house effect can be described as the energy given off by earth is reflected off of earth's atmosphere back down to the surface.
When energy from the sun passes through the atmosphere, some are absorbed which keeps the earth surface warm. While the rest is reflected back largely by cloud.
The energy which is emitted from the earth surface is called the infrared radiation. Some of the infrared radiation passess through the atmosphere but most is absorbed and re- emitted in all directions by the greenhouse gas molecules and clouds. This effect warms the earth surface and the lower atmosphere. Therefore this statement (Energy given off by earth is reflected off of earth's atmosphere back down to the surface) is correct about greenhouse effect.
For the greenhouse effect to occur, greenhouse gas molecules are mostly needed. Examples of these gases include:
--> Carbon dioxide (CO2),
--> Water vapor (H2O), and
--> Methane (CH4)
Over the years, the excessive human activities has lead to increase in the greenhouse gas molecules which has negatively affected the greenhouse effects.

A metal sphere of radius 10 cm carries a charge of 2.0 MicroCoulomb.What is the magnitude of the electric field 5.0 cm from the sphere's surface?
Answer:
E = 7200 J = 7.2 KJ
Explanation:
The electric field due to a sphere is similar to the electric field due to a point charge. It is calculated by the use of the following formula:
[tex]E = \frac{kq}{r^2}\\[/tex]
where,
E = Electric Field = ?
k = Coulomb Constant = 9 x 10⁹ Nm²/C²
q = charge on sphere = 2 μC = 2 x 10⁻⁶ C
r = distance from the center of the sphere to the location = 5 cm = 0.05 m
Therefore,
[tex]E = \frac{(9\ x\ 10^9\ Nm^2/C^2)(2\ x\ 10^{-6}\ C)}{(0.05\ m)^2}[/tex]
E = 7200 J = 7.2 KJ

Running water has materials such as dirt, sand, and dead plants and animals in it. When this water ends up in a lake, the materials it was carrying fall to the bottom of the lake and form layers. A layer is thicker when more water enters the lake. For example, thick layers form during times of heavy rain, and thin layers form during times of little rain. Sometimes lakes dry up. The bottoms of dry lakes can change into rock. This rock will still have layers. A geologist studied one of these rocks made from the bottom of a lake. Which rock layer formed during the wettest season? Layer
Answer:
The outside layer is the wettest.

Q. Calculate the annual energy
consumption, in kW-h, of
a hair dryer that is rated
at 1400 W and is used for
7.0 min every day.
(The answer in the textbook is 60 kW•h)
Answer:
60 kWh
Explanation:
The computation of the annual energy consumption in KW-h is shown below:
As we know that
1 kw = 1000 w
So, for 1400 W it would be
= 1,400 ÷ 1,000
= 1.4 kW
Now the number of hours it used in a year
= 7 minutes × 365 days ÷ 60 minutes
= 42.58333 hours
So in one year it used
= 1.4 kW × 42.58333
= 59.61 kWh
= 60 kWh
calculate the magnitude of distance and displacement of a body moving in a complete circle
Answer:
Total distance = 2πr
Total displacement = 0
Explanation:
To Calculate the magnitude of distance and displacement of a body moving in a complete circle, we must come to these facts that:
The distance = circumference of the circle which is equal to the product of 2 ,pi and radius r
That is
Circumference = 2πr
Since velocity is changing and not constant, it is a vector quantity. Likewise displacement is a vector quantity.
The total displacement will be equal to zero.
Therefore, total distance is equal to the circumference of a circle while total displacement is equal to zero.

Explanation:
Delphina and Oribus are the same distance from the equator, and they are both near the ocean. Using the information in the map, what is likely to be true about the air temperature of the two places? Why?
The image of the map is missing, so i have attached it.
Answer:
The air temperature at oribus is warmer than the air temperature at Delphina.
Explanation:
Looking at the map, we can say that he wind will push ocean water that is turning and passing the coasts. Now, as a result, Energy will be transferred from the ocean to the air at Oribus and whereas energy is transferred from the air to the ocean at Delphina. Thus, the air temperature at Oribus will be warmer than that at Delphina.
