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.

Answer:

w = 40 Joules

Explanation:

Formula to get work:

W = F × S

where:

w = work/Joules

F = force/newtons

s = displacement/meters

substitute:

w = 20 × 2

w = 40J

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.

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

v = 2d/t

where;

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.

Answer:

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules

Explanation:

It is true that as the distance d between a planet and a moon is increased, the strength of tidal forces decreases linearly (i.e., the strength of tides scales as 1.

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.

Therefore, It is true that as the distance d between a planet and a moon is increased, the strength of tidal forces decreases linearly (i.e., the strength of tides scales as 1.

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.

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

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.

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.

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

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.  

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)

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.

Answer:

A, C

Explanation:

It can be found in objects like a swing. It creates kinetic energy when it is coming back or going away, while moving.

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)
