How Do Smoke Particles Move in a Glass Tube Observed Under a Microscope?

AI Thread Summary
A microscope is necessary to observe smoke particles in a glass tube because they are too small to be seen with the naked eye. The smoke particles appear as spots of light due to the scattering of light by these tiny particles. Their movement is influenced by the random motion of air molecules, which collide with the smoke particles, causing them to move in various directions. Understanding these principles helps explain the behavior of particles in a fluid medium. This discussion highlights the importance of microscopy in studying small particles and their interactions.

Homework Statement



Using a microscope, smoke particles can be seen moving inside a glass tube. They appear as tiny spots of light that move in various directions. The air molecules inside the glass tube cannot be seen with the aid of the microscope.

a) State why a microscope is needed to see the smoke particles.

b) Explain why the smoke particles appear as spots of light.

c) State what makes the smoke particle moves in this way.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
