What is the wavelength of electromagnetic radiation with a frequency of 5.00 x 10^12 Hz? S
Angelina_Jolie [31]

Answer:

Infrared

Explanation:

To calculate the wavelength if the electromagnetic radiation, we must use the following formula:

c = f × λ

where c is the speed of the wave (in this case it's the speed of light, which is 3 × 10^{8} m/s) , f is the frequency and λ is the wavelength.

Using this formula, all we have to do is plug in our values and rearrange for the answer:

c = f × λ

3 × 10^{8} = 5.00 x 10^{12} Hz × λ

λ = 3 × 10^{8}/5.00 x 10^{12}

λ = 6.00 × 10^{-5} m = 6.00 ×10^{4} nm

Now that we know the wavelength we can figure out which kind of electromagnetic radiation this is.

6.00 ×10^{4} nm falls in the range of infrared radiation. We know this either from memorizing the values of the wavelengths or looking up a reference.

A client comes to the emergency department with status asthmaticus. His respiratory rate is 48 breaths/minute, and he is wheezin
Tema [17]

Answer:

The disorder is called Respiratory alkalosis

Explanation:

A client with asthma can hyperventilate (excess of O2). This oxygen excess can lead also to a lack of carbon dioxide (CO2) (acid substance) which can causes alkalosis (increasing the pH values in blood and body).

In this medical condition (respiratory alkalosis), the bicarbonate (HCO3-) hosted in the kidneys has a late response, so the  HCO3- level  in the client remains normal.

The PaCO2 (partial pressure of arterial carbon dioxide) is low in comparison with normal values so that indicates loss of CO2 in the respiratory system.

Si una masa dada de hidrógeno ocupa 40 litros a 700 grados torr. ¿Qué volumen ocupará a 1 atmósfera de presión? (dar la presión
Svetach [21]

Answer:

V_2=36.84L

Explanation:

Hola,

En este caso, podemos usar la ley de Boyle, la cual nos permite analizar el comportamiento volumen-presión en un gas ideal de manera inversamente propocional:

P_1V_1=P_2V_2

Así, dado el volumen y la presión inicial, la cual se convierte a atmósferas (760 torr = 1atm), calculamos el volumen final a 1 atm como se muestra a continuación:

V_2=\frac{P_1V_1}{P_2}=\frac{700torr*\frac{1atm}{760torr}*40l }{1atm}\\  \\V_2=36.84L

Saludos!

What is the atomic mass of<br> an atom?
Alborosie

Answer:

1 unit

Explanation:

It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units.

1/12 * 12 = 1. I think so.
