Answer:
1. Plateau where the temperature stays constant
2. Melting
3. Boiling points of the substance
Explanation:
The relationship between kinetic energy and temperature is given as follows;

Where;
= The average kinetic energy of the atom
R = The universal gas constant
= Avogadro's number
T = The temperature in Kelvin
Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance
Therefore, we have;
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. <u>plateau where the temperature stays constant</u> on a heating curve, which occur at the 2. <u>melting</u> and 3. <u>boiling points of the substance.</u>
Chlorine needs to gain one electron and sodium needs to lose one electron

1. velocidad media = desplazamiento/tiempo
desplazamiento = 0 porque el athelete vuelve al punto inicial en un círculo
velocidad media = desplazamiento/tiempo = 0/10 = 0
2. la distancia entre A y B es 5 cm porque
a^2 + b^2 = c^2 (el teorema de Pitágoras) así:
rapidez media = distancia/tiempo = 5/5 = 1 cm/s o 0.01 m/s
y yo no se cómo hacer 3-5 :( lo siento
3. Creo que es dos triángulo
s AB y CD menos la línea de fondo
5. Creo que es E + F porque B y D b y d cancelarse el uno al otro y C y C tambien pero no lo sé con seguridad.
Answer:
f = 23.64 Hz
Explanation:
From the wave equation, the relationship between frequency and wavelength is given by;
f = cλ
Where;
λ is wavelength
c is speed of light with a constant value of 3 × 10^(8) m/s
f is frequency
We are given wavelength of 7.88 x 10^(-8) m
Thus;
f = 7.88 x 10^(-8) × 3 × 10^(8)
f = 23.64 Hz
In vacuum and empty space, it's 299,792,458 meters per second
(186,282.4 miles per second).
In any material stuff, it's somewhat less. How much less depends on
what stuff it is ... it's different in each material "medium".
