When you rub glass with cotton is it negatively charged or positively?
When you rub glass with cotton, the glass becomes positively charged. This occurs because electrons are transferred from the glass to the cotton, resulting in a deficiency of electrons in the glass. Consequently, the glass ends up with a positive charge, while the cotton gains a negative charge.
Does a glass tumbler containing hot water crack if you cool it by pouring cold water on it?
Yes, it is possible for a glass tumbler containing hot water to crack if you cool it rapidly by pouring cold water on it. The sudden change in temperature can create stress within the glass, causing it to crack or shatter. It is recommended to gradually cool the glass to prevent this from happening.
What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
The colour of light which travels through glass with the minimum speed is?
The color of light that travels through glass with the minimum speed is violet. This is because the speed of light in any medium, including glass, is dependent on the medium's refractive index, with shorter wavelengths like violet experiencing a slower speed.
Light traveling from air into glass has an angle of 45 degrees The angle of refraction in the glass is most likely?
The angle of refraction in the glass is likely to be less than 45 degrees since light bends towards the normal when it passes from a less dense medium (air) to a denser medium (glass). The exact angle of refraction can be calculated using Snell's Law: n₁sinθ₁ = n₂sinθ₂, where n₁ and n₂ are the refractive indices of air and glass, respectively.

What is glass medium can send messages?
a glass medium to send messages
What is the better insulator among iron glass cotton plastic?
From best to worse, it would be glass, plastic, cotton and iron.
What is the glass transition temperature of cotton?
It doesn't have
A sealed glass float with a calibrated paper scale in its stem With a slight spinning motion it is placed into a cylinder containing a urine sample and the value is read at the meniscus of the urine?
culture and senstivity
Why do you think you were able to fit the cotton into the glass without the water overflowing?
The cotton will soak up the water.
Why is a wine glass containing wine less stable than a wine glass with no wine?
Wine glass containing wine is less stable than an empty wine glass because winecreates a high centre of gravity, thus it is likely to topple over.Hope this helps :)
What is luminescent glass?
Luminescent glass is a glass containing or coated with a dye that absorbs sunlight. It emits light at longer wave lengths.
Does light have a medium to travel through?
No, apart from "spacetime". But it CAN travel through a medium such as air or glass.
What does cotton plastic wood and glass have in common?
None are flammable
In which medium will a lens behave as a glass slab?
the medium which have the same refractive index as glass.
A wine glass containing wine is less stable?
Wine glass containing wine tends to create a high centre of gravity which makes it less stable,so it is likely to topple over.
