Answer:

The purpose of using a chemical reaction is to diagram a reaction, where the left side is formed by reactants and the right side is formed by the product. Through diagraming a reaction, chemists can hypothetically change parts of the both components, that way they would see what to expect in the reaction. Also, they can measure the approximation of amount of mass they would need, and see how components will change after the reaction

Answer:

0.88 volts

Explanation:

We are given the amount of charge of a point ( 7.3 × 10^-17 ) along with its potential energy ( 6.4 × 10^-17 joules ).

We are to find the electrical potential at this point.

To find this, we will use the following formula:

[tex]V = \frac{Ep}{q}[/tex]

Substituting the given values in the above formula:

[tex]V = \frac{Ep}{q}V = \frac{6.4 * 10^{-17}\:J}{7.3 * 10^{-17}\:C}[/tex]

V = 0.88 volts

Answer:

V= 1.32 V

Explanation:

Electrical potential energy is calculated using the equation

Ue=1/2CV² where C is the charge and V the voltage at that point in space.

Making V the subject of the formula;

V= √( 2Ue /C)

V= √(2×6.4×10⁻¹⁷÷(7.3 × 10⁻¹⁷))

= 1.32 V

Answer:

One characteristic of the moon of Earth is that it basically has no atmosphere. The Earth has an atmosphere rich in Nitrogen and Oxygen but on the moon the surface is directly exposed to outer space. There are three reasons why the moon has no atmosphere. The primary reason is because the moon is too small. Compared to the Earth, the moon is about 1/4th the size. This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead. There are currently no significant processes that allow for abundant gases to supply an atmosphere. The early moon may have had an atmosphere when it was geologically active but the crust of the moon is currently “frozen” into place and thus there are very little gases being emitted as compared to Earth. Another reason is because the moon is relatively close to the sun. This reason is tied closely to the moon having weak gravity. The solar wind from the sun helps strip away a weak atmosphere. Earth and Venus do not suffer the same fate since the gravity is high enough to hold the atmosphere in place. There are other moons in the outer solar system that are better able to hold an atmosphere due to being further away from the sun among other reasons.

Answer:

If sound intensity increases by a factor of 10, the decibel reading increases by 10.

Explanation:

Decibel scale:

In order to express levels of sound meaningfully in numbers that are more manageable, a logarithmic scale is used, rather than a linear one. This scale is the decibel scale. every increase of 3 dB represents a doubling of sound intensity.

Increase in decibel scale is given by the formula:

n = 10*log(Increased Intensity of sound/Original Intensity of Sound

n = 10*log(I/I₀)

In our case the sound intensity increases by a factor of 10. So I/I₀ increased by 10 times and will be 10 I/I₀

n = 10*log(10 I/I₀)

n = 10*log(10) + 10log(I/I₀)

n = 10 + 10*log(I/I₀)

This shows that the decibel reading is increased by 10 points.

One benefit of the SI system is that it is 'based on multiples of 10'.

Explanation:

One main benefit of the SI system is that it is based on multiples of 10. Which means that conversion to similar units is easier.

For example, you just need to multiply or divide by 10 to change from grams to kilograms and vice versa.

Also, the standard units defined by the International System of Units are consistent around the world which makes it easier to comprehend and communicate using them.

The SI system, or International System of Units, is beneficial because it is a universal and standardized system of measurement used worldwide in scientific domains. This avoid the need for unit conversion and ensures consistency in scientific communication.

One benefit of the SI system, which stands for International System of Units, is that it is universal. This means it is widely used throughout the world in all domains of scientific measurement. It's a standardized system of measurement that uses seven base units, including the meter for length, the kilogram for mass, and the second for time, among others.

This makes it easier for scientists, researchers, and students alike to understand and communicate data without needing to convert units. Its universality and consistency make it a fundamentally important tool in many fields including physics, engineering, and chemistry.

This Is A "True" Statement.

A scientific law tells us what nature will do under certain conditions.

Answer:

B and D

Explanation:

The higher the voltage, the more current flowing and the better the magnetic field. Using a longer wire will result in more electric force around the nail, making it stronger.

The stronger electromagnet can be achieved using a high voltage than the actual.

Answer: Option B

Explanation:

The strength of the electromagnet depends upon the factors such as the current or voltage, then the number of coils present or the iron core. These all are directly influencing factors in respect to proportionality.

Out of the options given, using fewer coils will weaken the electromagnet. Using shorter nail will again weaken. Shorter wire would increase the strength. Therefore, the best suitable change is the use of higher voltage.

Rhythmic Gymnastics

Explanation:

In general, the judges in the sports tend to be in charge for correcting and controlling the breaking of the rules in the particular sport. They are allowed to punish the competitors in accordance with the breaking of the rule, or they are there in order to determine weather a point is regular or not. In the rhythmic gymnastics though, and sports similar to it, the judges have different role, as they are in charge of determining the points earned by the competitors. This is done in a manner where every judge gives certain amount of points, or grades, and when those are summed up, the competitors get their total points.

Answer:

C. 1.04%

Explanation:

The following information has been provided;

Actual density of gold; 19.3 g/cm^3

Observed/measured density of gold; 19.1 g/cm^3

The formula for percent error is given as;

((actual value - observed value)/actual value)) * 100

[tex]\frac{19.3-19.1}{19.3}*100=1.0363[/tex]

The percent error of the student's measurement is thus 1.04%

The percent error of the student's measurement is 1.04%.

The percent error of the student's measurement can be calculated using the formula:

Percent error = |(measured value - accepted value) / accepted value| * 100%

In this case, the student measured the density of gold to be 19.1 g/cm^3, while the accepted value is 19.3 g/cm^3. Plugging these values into the formula, we get:

Percent error = |(19.1 - 19.3) / 19.3| * 100% = 0.104 * 100% = 1.04%

Therefore, the percent error of the student's measurement is 1.04% (option C).

Answer:

A. Conduction

Explanation:

Heat is transferred from one object to another but does not involve the movement of particles between the two objects. The only condition for this to happen is for the objects to be in contact. Contact ensures that adjacent particles transmit energy between them. It is measured in watts per meter per kelvin W/mK

Insulation prevents transfer of heat.

Thermal expansion is one effect of transfer of heat.

Conduction is one of the three ways to transfer heat, and one of the two ways to do it without transferring matter. (A)

22N to the right and 13N to the left

Forces are in opposite directions so you subtract the bigger force from the smaller force

Magnitude of force= 22N -13N

= 9N

net force direction is to the right

Answer: false

Explanation:

Answer:

False

Explanation:

If the object covers 9.8 m every second then it has a constant velocity of 9.8 m/s

The acceleration implies that there is a change in velocity. With a constant acceleration the velocity will change linearly.

[tex]S = ut + \frac{1}{2} gt^2[/tex]

The distance traveled each second will not be a constant, it will be a quadratic function as mentioned above.

Answer:

For this, you need the pythagorean theorem, which is a^{2}+ b^{2}= c^{2}

Your a should be 12, and your b should be 35. So now you can solve for c, which equals 37 miles.

So the answer is 37 miles

Answer:

f = 6.912 E14 Hz

Explanation:

The speed of the wave is defined as

speed = wavelength*frequency

the frequency of the photon  is defined as

f = speed / wavelength

f = 3 E8 m/s / 434 E-9 m

f = 6.912 E14 Hz

Answer:

Frequency,  [tex]f=6.91\times 10^{14}\ Hz[/tex]

Explanation:

It is given that,

Wavelength, [tex]\lambda=434\times 10^{-9}\ m[/tex]

Speed of light, [tex]c=3\times 10^8\ m/s[/tex]

The frequency of photon can be calculated using following relation as :

[tex]c=f\times \lambda[/tex]

[tex]f=\dfrac{c}{\lambda}[/tex]

[tex]f=\dfrac{3\times 10^8\ m/s}{434\times 10^{-9}}[/tex]

[tex]f=6.91\times 10^{14}\ Hz[/tex]

So, the frequency of the photon is [tex]f=6.91\times 10^{14}\ Hz[/tex]. Hence, this is the required solution.

Answer:

The magnets are repealing from each other is because the poles are the same on the magnets so they are pushing away from each other.

Explanation:

Magnets can either attract or repel each other. A permanent magnet is an object that produces a magnetic field around itself. It is this field that enables them to stick to each other and to some types of metal. Specifically, they stick to ferromagnetic materials like iron and things that contain iron, such as steel

Explanation:

A magnet is defined as a bar magnet that produces a magnetic field which attracts or repel other objects.

A magnet has both a north pole and a south pole.  

As like charges repel each other and opposite charges attract each other. Similarly, like poles repel each other and opposite poles attract each other.

So, when south pole of a magnet comes in contact with north pole of another magnet then they will attract each other.

As the given image shows that magnets are away from each other this means that they are repelling each other.
