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.

b. It is found only in living things.
c. Its amount depends on the moving object's speed.

Light of frequency 2.5 x 1015 Hz illuminates a
piece of iron, and the iron emits photoelectrons
with a maximum kinetic energy of 6.3 eV. What is
the threshold frequency of the metal? Planck's
constant is 6.63 x 10-34 J·s.
.
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)
When the north pole is tilted toward the sun, which area has the fewest hours of daylight?.
Answer:
The earth revolves around the sun in a plane called the ecliptic.
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.
This is called the summer solstice in the northern hemisphere. and occurs around June 21.

An ideal gas is taken through a cyclic thermodynamic process through four steps. The amounts of heat given to the system in these steps are Q{1} = 1000J, Q{2} = - 800J, Q{3} = 450J , Q{4} = - 200 J respectively. The efficiency of cycle is nearly
Need full Explanation ! Answer is already marked in attachment just need the explanation or the way to reach the answer
We are given to find efficiency of the cycle.
We Know
Efficiency is denoted by the symbol "η"
[tex] \text{η\%} = \frac{ \text{Output Work}}{ \text{Heat Supplied } } \times 100[/tex]
As it is a cyclic process, So,
[tex] \triangle \text{U} = 0 \\ \implies \triangle \text{ Q} = \triangle \text{W} + \triangle \text {U} \\ \implies\triangle \text{ Q} = \triangle \text{W} + 0 \\ \implies \triangle \text{Q} = \triangle \text{W}[/tex]
[tex] \text{Let us first calculate} \: \triangle \text{Q}[/tex]
[tex]\triangle \text{Q} = \text{Q}_1 + \text{Q}_2 + \text{Q}_3 + \text{Q}_4[/tex]
[tex]\triangle \text{Q} = 1000 + ( - 800) + 450 + (- 200) \\ \\ \implies\triangle \text{Q} = 1000 - 800 + 450 - 200 \\ \\ \implies \triangle \text{Q} = 450 \text{J}[/tex]
[tex]\therefore \text{ Net Output Work i.e., ∆W = 450 J}[/tex]
Now, We need to find the Heat Input.
We know, Heat Input is always the sum of all positive heats
[tex] \because {∆Q_{in}} = \text{∆Q}_1 + \text{∆Q}_3 \\ \\ 1000 + 450 = 1450 \text{J}[/tex]
Now We Have To Find The η%
[tex] \text{η\%} = \frac{ \text{Output Work}}{ \text{Heat Supplied } } \times 100[/tex]
[tex] \text{η\%} = \frac{ \text{450}}{ \text{1450 } } \times 100 \\ \\ \implies \text{η\%} = \frac{ \text{450}}{ \text{145} \cancel{0 } } \times 10 \cancel0 \\ \\ \implies\text{η\%} = \frac{ \text{450}}{ \text{145 } } \times 10 \\ \\ \implies{ \text{η\%}} = \frac { \cancel{450}}{ \cancel{145}} \times 10 \: \: \: \: \fbox{cancelling by 5} \\ \\ \implies{ \text{η\%}} = \frac{90}{29} \times 10 \\ \\ \implies{ \text{η\%}} = 31.0344\% \\ \\ \implies{ \text{η\%}} = \red{31\%}[/tex]

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.
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 wavelengthFrequency 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.

The x component of a vector that is defined as 852 cos 302°. Both the direction and the magnitude are required to define.
What is vector?Vectors seem to be a physical quantity with both magnitude and direction. While the scaler is the only quantity which is defined by the magnitude.
For example, distance is the scaler and the displacement is the vector quantity. Vector is shown by an arrow on the quantity.
A vector's scalar x-component is equal to the product of its magnitude and the cosine of its direction angle.

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?
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 waveThe 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 motionv = (2 x 715) / (13)

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