What is the frequency,in Hz,of electromagnetic radiation that has a wavelength of 1.25m

Kryger [21]

Answer:

$f=2x10^8Hz$

Explanation:

Hello!

In this case, given that frequency of the electromagnetic radiation showing off a wavelength of 1.25 m is computed by using the speed of light as shown below:

$f=\frac{c}{\lambda }$

We plug in the wavelength and speed of light to obtain:

$f=\frac{3x10^8m/s}{1.25m } \\\\f=2x10^8Hz$

Best regards!

Why is the air in a jet aircraft flying at high altitudes pressurized? *

saw5 [17]

Answer:

Aircraft cabins are therefore pressurized to maintained a similar pressure as that experienced at sea level to ensure normal breathing of passengers.

Explanation:

-Air becomes increasingly thinner with increasing altitudes.

-As such, oxygen becomes limited at higher altitudes and makes it difficult or almost impossible to breath a condition called hypoxia.

-Aircraft cabins are therefore pressurized to maintained a similar pressure as that experienced at sea level to ensure normal breathing of passengers.

How many moles are in 60.0 grams of water?

Mashutka [201]

<h3>Answer:</h3>

3.33 mol H₂O

<h3>General Formulas and Concepts:</h3>

Left to Right

<u>Chemistry</u>

<u>Atomic Structure</u>

Reading a Periodic Table
Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

60.0 g H₂O (Water)

<u>Step 2: Identify Conversions</u>

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 60.0 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O})$
Multiply: $\displaystyle 3.32963 \ mol \ H_2O$

<u>Step 4: Convert</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

3.32963 mol H₂O ≈ 3.33 mol H₂O
