Answer:
wavelength = 0.56 × 10⁻² m
Explanation:
Given data:
Frequency of radiation = 5.4 × 10¹⁰ Hz
Wavelength = ?
Solution:
Formula:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)
wavelength = 0.56 × 10⁻² m
Matter is found every where in the universe and there is never any substance in the universe that is not composed of matter.
<h3>What is matter?</h3>
Matter is anything that has weight and occupy space. We know that matter is present in every part of the universe. Everything in the universe is composed of matter. Matter forms the basics of our study of the universe. Water, food cloths everything all are composed of matter.
The fact that matter inundates the universe has made the study of matter an unavoidable topic. As such, we can not really be able to point something that is of made up of matter. There can be no such thing!
As long as a thing does exist in the material universe, that thing is made up of matter. Look at yourself for example, matter is spread all across your body. The same occurs in the bodies of every other living thing.
The nonliving things are not also left out as they are equally composed of diverse kinds of matter that exists in the universe.

Answer:
a. All of the below
Explanation:
Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture.
TLC can be used to analyze a chemical reaction to determine if the reactants have been consumed and a new product has formed. Running a tlc of ferrocene, the acetylferrocene product mixture, and co-spot, when you view the TLC plate under a UV light, you will notice that acetylferrocene product is on the right-most lane, this shows that the reaction appears to be a success: the higher spot of ferrocene has been consumed), and a new product spot is present. From these we can observe that the we can use this to identify the number of products of the reaction, determine if the starting material is still present in the reaction and the elution in a chromatography column of the starting material and products. Therefore, all the choices are correct.
The answer is choice (1).
In case you're interested in the solution for future reference:
-- Density = (mass) / (volume)
-- The scale shows that the mass of the sample is 60 grams.
-- The graduated cylinder has 24 mL in it <em>without</em> the sample.
The graduated cylinder has 34 mL in it <em>with</em> the sample.
The volume of the sample is (34mL - 24mL) = 10 mL .
-- Density = mass/volume = 60g / 10mL = 6 g/mL
