Energy can generally be considered to be either kinetic energy or potential energy. Some specific forms of energy, such as electrical, magnetic, and gravitational energy, can operate in the space around objects and affect other objects that come near. In these examples,
Answer: The options are not given.
Here are the options.
A. energy is continuously created.
B. energy is continuously destroyed.
C. energy exists in a field.
D. all of these
The correct option is C.
Energy exists in a field.
Explanation:
Energy is the ability to do work or the property i.e force or power that is moved to an object so that it can perform work.
Energy exists in a field because a field is a region in which each area is affected by a force or power on an object . For example a paper clip placed on a magnetic field require a force or power to be able to attract or repel magnets.
An electric field surronds an electric charge when another particle is around it, it uses energy to either attract or repel the object e.t.c.
Therefore energy exists in field.
How Can the human ear detect the sound
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
Explanation:
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Why would the CPSC perform studies when other soap and detergent companies have already conducted research on the same products? The CPSC is the only organization that can test the safety of soaps and detergents. Studies conducted by any company that benefits financially are considered unreliable. Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company. Tests performed by the CPSC follow established scientific methods, but those performed by soap companies do not.
Answer: Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.
Explanation:
The function of Consumer Product Safety Commission is to make sure that the products which are used by consumers are safe and also make sure that companies meet the required and acceptable safety standards. The products that are seen to be harmful to the health of the consumers are banned.
Regarding the question above, CPSC would perform studies when other soap and detergent companies have already conducted research on the same products because the studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.

What is the speed of an object that travels 60 meters in 4 seconds?
a) 240 m/s
b) 15 m/s
c) 0.067 m/s
d) 15 mph
Answer:
B) 15 m/s
Explanation:
Since most of the answer choices are in m/s, you can try dividing 60 meters/4 seconds in order to get the seconds on the bottom to become 1 second.
You want to find how many meters the object can travel in 1 second, rather than 4 seconds.
[tex]\frac{60 \ m}{4 \ s} \div \frac{4}{4} = \frac{15 \ m}{1 \ s}[/tex]Now you can see that for every 1 second of time, the object can travel 15 meters. This corresponds to answer choice B) 15 m/s.
The last option, D, is incorrect because we are not dealing with hours as our unit of time. We are dealing with seconds.
Answer:
b) 15 m/s

A moving car skids to a stop with the wheels locked across a level roadway. Of the forces listed, identify which act on the car.
Normal
Gravity
Applied
Friction
Tension
Air resistance
Answer:
Normal, Gravity, Friction, and Air Resistance.
Explanation:
When a moving car skid to stop and its wheels are locked across, then the following forces will be applied on the car:
Normal force: It will act counter to gravity that pushes an object against a surface and acts perpendicular to the contact surface.
Gravity: Gravity force acts in each and every object having mass and it can not be avoidable. So, the gravity force will also apply to the car and attract it to the earth's surface.
Friction: Friction is a force that acts opposite to the motion and stops or slows motion. Friction will be applied to the car that will oppose the motion of the car and stop it.
Air resistance: air resistance is defined as the forces exerted by air that acts opposite to the relative motion of an object. Air resistance will also be applied to the car when it will skid to stop as we are always surrounded by the air.
Hence, the correct answers are "Normal, Gravity, Friction, and Air Resistance."

why might a CD be a more reliable way to copy and distribute a sound recording than a vinyl record
Answer:
Is either b or d
Explanation:
A CD be a more reliable way to copy and distribute a sound recording than a vinyl record because a CD is easier to copy exactly over and over again.
What are CDs and vinyl records?CDs are digital music storage devices, which means the music is binary data encoded. It uses a 2-channel, 16-bit, 44.1 kHz configuration as the norm for CDs. A laser reads the data, and after it has been decoded, audio is played back.
A sensitive needle known as a stylus is used to read the physical record of the music that is imprinted on the vinyl disc because vinyl is an analogue storage medium. The 12-inch 33-rpm LP, 7-inch 33-rpm EP, and 7-inch 45-rpm single make up the typical vinyl album.
The diameter and playback speed are what determine a vinyl disc's storage capacity (larger discs and slower playback means more capacity). The stereo channels are divided among the groove's two sides.
Hence, option (D) is correct.

You row a boat perpendicular to the shore of a river that flows at 3 m/s. The velocity of your boat is 4 m/s relative to the water. What is the velocity of your boat relative to the shore?
Answer:
The velocity vBW of the boat relative to the water is 4.0 m/s, directed perpendicular to the current, as in Figure 3.18.
Explanation:
The boat is perpendicular to the shore. Then the net velocity of the boat with respect to river is 5 m/s. The observer feels like the boat is moving slower than they appear actually.
What is relative velocity ?Relative velocity is velocity of an object measured with respect to other object which can be of stationary or moving with a speed. Thus speed relative to another object is called the relative velocity.
The relative velocity is what's the speed for an observer but it differs from actual velocity. Sometimes it may slower or faster depending on the object with which a we are relating the speed.
Given that the speed of the boat = 4 m/s
speed of river = 3 m/s.
Both are perpendicular and the net velocity of the boat is :
r = √(3² + 4²) = 5 m/s.
Hence, the velocity of the boat relative to the shore will be 5 m/s.

Explanation:
Estimate the total mass of ocean on earth
The town of Seaside needs to build a new power plant. The old coal burning plant produces too much pollution and is no longer safe. The mayor decides that he will do some research on alternative forms of energy like nuclear power plants and solar power plants.
What types of resources should the mayor use to conduct his research? Why would these be considered reliable sources of information and why? What types of resources are reliable? How can he use what he learns to make the best decision for the town?
The mayor is making a good decision to do research into renewable forms of energy. Not only does coal produce pollution, it also contributes to greenhouse gas emissions. Plus, the supply of coal is a finite source. It is considered a natural resource instead of renewable. That means that eventually the supply of coal will run out at some point. Renewables do not encounter such a problem.
So it's smart to look into alternative forms of energy such as nuclear or solar. The benefit of nuclear is that it produces a lot of energy and does so efficiently. The downside is that it's that accidents would lead to disastrous outcomes (eg: the nuclear disaster in Japan). Also, there's the issue of what to do with the nuclear waste. The waste itself is very dangerous and it must be buried underground sealed in thick containers. This is an expensive operation. The rate of decay of the material takes a long time, which means that future generations hundreds of years down the line will have to deal with the waste.
Solar is a cleaner alternative to nuclear, but unfortunately it is not as efficient compared to nuclear power. You need a lot of solar panels in a vast open area to be able to get the energy to power many homes. Places out in the desert are a good choice to put the solar farms because the sun shines intensely there and not many people (or no people) live out in remote areas such as that one.
Because the town is called Seaside, it seems like this town is on the coast. If so, then the mayor should look into wind power to complement solar power. Wind along the coast is often very intense due to the sea current and jet stream. The downside to wind power is that some days the wind doesn't blow at all. The mayor could also look into tidal power which harnesses the flow of the tides coming in and out. If a major river is nearby (that flows into the ocean) then s/he could consider hydroelectric power as well. There are many renewable options to pick from. Each option has its pros and cons, so it's up to the mayor to weigh what exactly their needs are and how efficiently they want electricity. Mixing various options is possibly the best idea since you get a bit of each pro/con from all the options mentioned.

OThe rest of the bulbs continue to shine at a higher brightness
OThe rest of the bulbs stop shining and shut off.
Answer:
D. The rest of the bulbs stop shining and shut off.
Explanation:
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off. Option D is correct.
What is an electric bulb?
An electric bulb is a gadget that uses electricity to create visible light. It is the most popular type of artificial lighting and is necessary for modern society.
The light bulb is connected to a switch in a parallel configuration. The switch is open, which means there will be a lot of resistance and no current will flow via this route.
Across the parallel connection, the battery would create the same potential difference. Because the current would not go via the open switch, it would instead flow through the light bulb, causing it to illuminate.
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off.
Hence, option D is correct.

If all objects that have mass also have gravity, why doesn't your pencil get pulled towards you while it sits on your desk?
Answer:
The pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.
Explanation:
Let us apply Newton's Law of Gravitation between a person and pencil.
Average Mass of a Normal Pencil = m₁ = 10 g = 0.01 kg
Average Mass of a Person = m₂ = 80 kg
Distance between both = r = 1 cm = 0.01 m (Taking minimal distance)
Gravitational Constant = G = 6.67 x 10⁻¹¹ N.m²/kg²
So,
F = Gm₁m₂/r²
F = (6.67 x 10⁻¹¹ N.m²/kg²)(0.01 kg)(80 kg)/(0.01 m)²
F = 5.34 x 10⁻⁷ N
This Force is very small in magnitude due to the light masses of both objects.
Therefore, the pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.
Yodelin has fifty quarters and dimes. Their total value is $9.80. Which of these systems of equations can be used to find the number of quarters (q) and
dimes (d) Yodelin has?
Answer:
q + d = 50
25q + 10d = 980
Explanation:
The equation that can be employed to determine the number of quarters(q), as well as, dimes(d) that Yodelin has would be:
q + d = 50...(1)
25q + 10d = 980...(2)
Multiplying (1) by 25
25q + 25d = 1250 ...(3)
25q + 10d = 980...(4)
subtracting (4) from (3)
15d = 270
d = 18
q = 50 - 18
= 32
The system of the equations could be
q + d = 50
25q + 10d = 980
Calculation of the equation and the number of quarters and dimes:Since Yodelin has fifty quarters and dimes. Their total value is $9.80.
So here the equations be
q + d = 50...(1)
25q + 10d = 980...(2)
Now we have to Multiplying (1) by 25
So,
25q + 25d = 1250 ...(3)
25q + 10d = 980...(4)
Now
subtracting (4) from (3)
15d = 270
d = 18
So,
q = 50 - 18
= 32

A car started its motion from rest and accelerated for 6 seconds, with the acceleration of 4 m/s2. Then it decelerated for 5 seconds, with the acceleration of -1.6 m/s2. What was the velocity of the car after 6+5 seconds?
Answer:
16 m/s
Explanation:
from the formula: a = velocity/time
you calculate the velocity in both cases (when time is 5 sec and 6 sec) by using the formula: velocity = a x time
v (5 sec) =24 m/s
v (6 sec) = - 8 m/s
then : add v (5 sec) to v (6 sec) and the result is 16 m/s
