What is Tidal force?.

Tidal force is the gravitational force that a body on a linear motion experiences which pull the body towards the center of the mass of another varying body because of the gravitational pull of that body at a distance.

C. The products have higher potential energy, and energy is
absorbed
D. The reactants have higher potential energy, and energy is released.

Answers

Answer: The Energy Change

Explanation: change for a chemical reaction can either be exothermic if it gives off heat or endothermic if it requires heat to proceed.  in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy. energy changes that occur during a chemical reaction can be shown in a diagram called a potential energy diagram, or sometimes called a reaction progress curve. A potential energy diagram shows the change in potential energy of a system as reactants are converted into products.

Answers

The center of mass is the point located in an average position concerning the objects' positions and their masses. (a/3;a/3) is the location of the COM.  

What si the center of mass?

The center of masses of a given system of particles or objects is the position under which all external forces are acting. Any uniform force acts on this point.

This position is the average position of all the components of the system concerning their masses. It can be placed in one, two or three dimensions according to the system.

Coordinate X of the center of masses is given by the following formula,

Xcom = Σ(Ximi) / Σmi

This is the adition (Σ) of each particle position on the X-axis (Xi) multiplied by their mass (mi), and the result divided by the summation of all masses -total mass-.

In the same way, coordinate Y of the center of masses is given by the following formula,

Ycom = Σ(Yimi) / Σmi

This is the adition (Σ) of each particle position on the Y-axis (Yi) multiplied by their mass (mi), and the result is divided by the summation of all masses.

The center of masses is located in the position (X, Y).

According to this framework, we can get the coordinates of the center of masses for this bidimensional system. Coordinates can be expressed in meters or centimeters (m or cm).

Data:

     Particle ⇒ (X;Y)

Ball 1 ⇒ (0;a)Ball 2 ⇒ (0;0)Ball 3 ⇒ (a;0)  

Coordinate X  ⇒  Xcom =  Σ(Ximi) / Σmi

                             Xcom =  (0m) + (0m) +(am) / m +m +m

                             Xcom =  am / 3m

                             Xcom =  a/3

Coordinate Y  ⇒  Ycom =  Σ(Yimi) / Σmi

                             Ycom =  (am) + (0m) +(0m) / m +m +m

                             Ycom =  am / 3m

                             Ycom =  a/3

Coordinates of the center of masses, (X;Y) = (a/3 ; a/3)

(a/3 ; a/3) is the location of the center of mass in the proposed bidimensional system.

Answers

Answer:

h f = W + KE

Input energy equals work function plus KE of emitted electron

W = 6.63E-34 * 2.5E15 - 6.3 * 1.6E-19

W = 6.63 * 2.5 * 10^-19 - 10.1 * E-19 ev     (1ev = 1.6E-19 J)

W = (16.6 - 10.1)E-19 = 6.5E-19 J

h f = 6.5E-19 J        for electrons to be emitted with zero KE

f = 6.5E-19 / 6.63E-34 = .98E-15 / sec = 9.8E-14 / sec  (threshold)

The poles of the earth are at an angle of about 23.5 deg from the ecliptic.

If the north pole is tilted at 23,5 deg towards a perpendicular to this plane (ecliptic) the south pole will be tilted at 23.5 deg away from this plane and will receive the least amount of sunshine.

In an experiment for measuring the speed of sound gun was shot 715 m away from the observer. It was heard 2. 13 seconds after the flash was seen. What was the speed of sound in air at that time?

Answers

The speed of the sound wave after the flash was seen, in the experiment for measuring the speed of sound gun is 110 m/s.

Speed of the sound wave

The speed of the sound wave can be determined by applying the principle of echoe as shown below;

v = 2d/t

where;

d is the distance of the sound wavet is time of motion

v = (2 x 715) / (13)

v = 110 m/s

Thus, the speed of the sound wave after the flash was seen, in the experiment for measuring the speed of sound gun is 110 m/s.

Daryl uses a microphone connected to an oscilloscope to study sound waves. He finds that higher pitched sounds have higher frequencies and shorter wavelengths while lower pitched sounds have lower frequencies and longer wavelengths. Daryl concludes that the relationship between the frequency and the wavelength of sound waves in air is the result of causation and not correlation. In two to three sentences, describe whether Daryl's conclusion is correct and explain why or why not.

Answers

In my opinion, the relationship between the frequency and the wavelength of sound waves in air is the result of correlation.

Relationship between frequency and wavelength

Frequency and wavelength are inversely proportional to each other which means if the frequency increases the wavelength decreases and when the frequency decreases, the wavelength increases.

So we can conclude that the relationship between the frequency and the wavelength of sound waves in air is the result of correlation.

Daryl's conclusion about the relationship between frequency and wavelength is accurate because this is the result of causation.

What is the difference between causation and correlation?

Causation implies one factor is the cause of another. For example, plants' need for the sun causes them to grow towards the sun.

On the other hand, correlation occurs if two factors are related and therefore the increase in one factor affects the other. For example, the amount of daylight affects plants' photosynthesis rate.

Are frequency and wavelenght an example of causation or correlation?

These two factors are an example of causation because a higher frequency in waaves leads to shorter wavelenghts and vice-versa.
