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>

<u>Math</u>

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • 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>

  1. Set up:                               \displaystyle 60.0 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O})
  2. 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
