How much water does a glass hold?
standard glass is 8oz, but it would depend on the glass.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
Water is projected from two rubber pipes at the same speed-from one at an angle of 30 and from the other at 60why are the ranges equal?
w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
What density does an object have to have to sink in water?
A density greater than that of water (which varies with temperature).
What has a greater mass 1 liter of water or 1 liter of alcohol?
Water.
What is the critical angle of perspex and water?
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
What is the critical angle of glass?
When light in glass of index of refraction n hits the surface at angle A relative to the surface normal (perpendicular line to the surface) it generally exits into the air at larger angle B. These three variables are related by Snell's Law: n Sin(A) = (1)Sin(B) (air has index of refraction approx. = 1 ) The critical angle A for internal reflection occurs when the exit angle is 90 so the exit light skims the surface. Anything larger then critical A and the light gets reflected back into the glass. So in Snell's law let B = 90; nSin(A) =(1)Sin(90) = (1)(1) so Sin(A) = 1/n For glass n ~ 1.5 so Sin(A) ~ .67 This is the sine of the critical angle. Now figure out what angle has a sign of .67 and Whala you have it.
What is the critical angle for light traveling from water into air?
48.6 degrees
Is density of glass greater than that of water and why?
it depends on the type of glass you are talking about.
What is the angle of polarisation for a ordinary glass and water?
As per Brewster's law, the angle of polarisation or polarising angle is got by the expression tan ip = mu. So for water mu = 1.33 and its polarizing angle = 53 deg 3 min For glass mu would vary for different glass such as flint etc.
Which has a greater volume lead in water or glass in water?
This depends on the mass.
Does water reflect or refract and why?
Both.Water is transparent to visible light but the speed of light in water is different to the speed of light in air. As a result, light rays travelling from air to water are usually refracted. However, as is the case at any interface between transparent media, light rays which hit the surface of the water at an angle greater than the critical angle are reflected.
The path of a light ray from glass into water?
Depends on the angle the light ray hits the water.
When you overfill your glass with water and theres a slight bulge at the top of the glass you are witnessing what property of water?
miniscus mate
Why does water wet glass and mercury does not?
Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion
An ice cube melts in a glass of water because?
Water temp is greater than 0 °C.
