Omg I wish I knew this one sorry
Hope you can figure it out
Answer:
λ = 6.25 × 10⁻¹⁰ m
x-ray
General Formulas and Concepts:
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
C = 3.0 × 10⁸ m/s
ν = 4.80 × 10¹⁷ Hz (s⁻¹)
λ = unknown
<u>Step 2: Solve for wavelength</u>
3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)
λ = 6.25 × 10⁻¹⁰ m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
6.25 has 3 sig figs. No changes necessary.
<u>Step 4: Identify</u>
6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum
Answer:
pH = 4.34
Explanation:
pH= -1/2(logKa) -1/2(log C)
= -1/2( log 5.98*10^-8) -1/2(log 0.0353)
=-1/2(-7.22)-1/2(-1.45)
=3.61+0.725= 4.34
By integrating two or even more materials whose properties are quite distinctive is composite materials. The different materials work together to build special properties for the composite, but within the composite one can easily tell the various materials apart that they don't dissolve or mix together.
It is also recognized as Fiber-Reinforced Polymer (FRP) composites, which are constructed from a polymer matrix strengthened with engineered, man-made or natural fiber like glass, steel or aramid or other strengthening material.
- Their high dimensional consistency helps them to preserve their shape, be it hot or cold, wet or dry.
- This renders them a common material for outdoor frameworks such as wind turbine blades.
- These have less resistance to cracking than metals but more durability than most polymers.
