Answer:
option A
Explanation:
the correct answer is option A
when the air temperature increases the relative humidity decreases.
When temperature increase the ability to hold water vapor decreases.
higher the water vapor more will be the amount of moisture content.
it take less water vapor to saturate air in a city with low temperature compared with high air temperature.
Answer:
Los cuerpos se encuentran luego de 15 segundos a los 300 metros.
Explanation:
El movimiento rectilíneo uniforme (MRU) es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir, que en este caso el movimiento es lineal en una única dirección y la velocidad de desplazamiento es constante.
La posición del cuerpo después de un tiempo se calcula a partir de la posición inicial y de la velocidad del cuerpo mediante la expresión:
x=x0+v⋅t
donde:
-
x0 es la posición inicial.
- v es la velocidad que tiene el cuerpo a lo largo del movimiento.
- t es el intervalo de tiempo durante el cual se mueve el cuerpo.
En este caso, si el tiempo empleado por el primer cuerpo es t, el del segundo que sale 5 segundos más tarde será t-5. Siendo la velocidad del primer cuerpo 20 m/s y la del segundo cuerpo 30 m/s, entones la posición de cada uno será:
x1 = 20 m/s* t
x2 = 30 m/s* (t - 5 s)
Ambos se encuentran cuando sus posiciones son iguales:
x2=x1
30*(t - 5) = 20*t
30*t - 30*5= 20*t
30*t - 150 = 20 t
30*t - 20*t= 150
10*t= 150
t= 150÷10
t=15 segundos
Reemplazando en la expresiones de posición obtienes:
x1 = 20 m/s* 15 s= 300 m
x2 = 30 m/s* (15 s - 5 s)= 300 m
<u><em>Los cuerpos se encuentran luego de 15 segundos a los 300 metros.</em></u>
Answer:
7 Electrons
Explanation:
Assuming that final energy level is that same as valence shell, we first need to find how many of the electrics will be used to fill the ones before it.
Electron shell capacities are as follows :
First shell/Ebergy level: 2 electrons
Seconds shell/energy level : 8 electrons
Third shell /energy level :8 electrons
The first two shells total to 10, and the first three shells total to 18. Since chlorine (17) fills more than 2 shells but less that 3, the third one is its final energy level. We find the number in the final energy level by subtracting the 10 in the full first two. 2+8=10
17-10=7
Chlorine has 7 electrons on its final energy level.
Hope this helped!
Answer:
Primary waves (P-waves)
Explanation:
Due to excess of the energy inside the earth when the tectonic plates begin to slide or fracture then the energy is released in the form of seismic waves, this causes the earthquake.
<u>Two types of seismic waves are generally responsible for the earth quakes:</u>
- body waves
- surface waves
Body waves are of two types:
Primary waves (P-waves)
These are the fastest of all the waves involved in the earth-quake which travel at a speed of 1.6 km to 8 km per second.
They can pass trough solids, liquids and gases. They arrive at the surface as an instant thud.
Secondary waves (S-waves)
They can only pass through the solids and they move slower than the P-waves.
As S-waves move, they displace the rock particles, pushing them outwards perpendicular to the wave-path that leads to the earthquake-related first rolling period.
Surface waves (L-waves/ long waves)
- These waves move along the surface of the earth. They are responsible for the earthquake's carnage.
- They move up and down the Earth's surface, rocking the foundations of man-made structures.
- Surface waves are slowest of the three waves, which means that they are the last to arrive. So at the end of an earthquake usually comes the most powerful shaking.
