questinon 72: Nitric acid is a corrosive chemical describes a chemical property, as it refers to nitric acid's ability to react and cause chemical change, such as corroding materials.
Ere 47 , 2 nw mihonw
Part 2
37 is A,not D (A) The speed of an electromagnetic radiation is the product of its wavelength and frequency,so as the frequency increase,so do the speed.so it's right (D) The speed of electromagnetic wave have different speed in different mediums.(i.e it doesn't have the same speed in air and water).it is the frequency that doesn't depend on the nature of the medium.

Thank you teacher pls part 2

Please next part
Teacher if you want you can check it on Physics G-10,U-6 old curriculum we know light is one of EMR as light travels from one medium to another there is refraction of light and this leads to change in speed of light. According to Snell's law SinQ1/SinQ2=n2/n1=V1/V2.So "A" is the correct answer🙏
68 "C" is the correct answer bcz there is no preferential discharge in molten electrolytes bcz we have only one cation and anion so they will migrate to their respective electrodes and got discharged.
Teacher መቼ ይጀምራል ዝም አልከን እኮ pls pls መልስልኝ የሚጀምር ከሆነም ቀኑን ይንገሩን በተስፋ እንጠብቅ ???please please❤❤

Teacher on question 37, the emr speed of light is constant this is because for example from gamma ray to radio wave the wavelength is increase and the frequency is decreases, so because of wavelength c is increase at the same time because of frequency it decrease, so it doesn't change . But the speed of light is change it travels from one medium to another medium. This is because the refractive index of the material. For example light travels from air to water it's speed decrease , because water has high refractive index , and because of this it's wavelength decrease and also it's speed. And teacher you can't see that speed of light is directly proportional to both wavelength and frequency . C=wavelength x frequency and text book also indicated that the speed of emr is depend on the medium which it travel through . On question 72, the corrosiveness of the nitric acid is because of it's strong oxidizing agent. So it is definetly chemical property. So the correct answer is the nitric acid has pungent smell. And also teacher you can't stand to opposite side of the text book , because the question is asked based on the text book.
light(photon) is electromagnetic wave/ don,t use Al bro but 72 questions tends to be B as answer
SPeed of light is constant in vacuum but not in medium
Is light require medium to travel?

Yes,bravo
The speed of electromagnetic wave depends on the nature of the medium which the wave is traveling
Is speed of light depends on medium kkk

Lela s7b
Q42/A
thank you teacher
Check on grade 11 unit 2 phage 60
no more questions (what is the difference b/n choice A and B,you have to know the relationship b/n frequency and wave length.you don't know -
Amzing you are best chemstry teacher thank you
72 b is the correct choice - B. Nitric acid has a pungent smell. (This describes a physical property, as it relates to the senses.) - C. Nitric acid is a corrosive chemical. (This describes a chemical property, as it relates to its ability to react with other materials.)
When you start
Teacher,question 25 and 39 correct answer is A
Sorry teacher question 37 is not D its A right because speed is dependent on medium refer grade 11 old curriculum textbook!
Sorry I mean A is correct Answer
Zendro remidan ynoral end
Speed: Electromagnetic radiation always travels at the same speed in a vacuum, which is the speed of light, approximately 299,792,458 meters per second (m/s). However, in other materials, such as air or water, the speed of electromagnetic radiation can be slower.
No ,that is speed light
is speed or frequency constant? and if the speed is constant why n is needed in refraction?
Brother speed of light constant yemihonew iko in vacuum new
Yes light only move through vacuum or not require medium
