Semenov [28]
Homogenous mixtures don't have visible constituents. An example of this would be water.

Heterogenous ones have visible constituents and an example would be if you put some dirt in water and then it wouldn't mix properly and you could see the dirt in it.

The acceleration due to gravity is lower on the Moon than on Earth. Which one of the following statements is true about the mass
VashaNatasha [74]

Answer:

Mass is the same, weight is less.

Explanation:

We know the following equation

W = mg

where m is the mass of the astronaut which is constant and W is the weight. As g (the acceleration due to gravity) is a variable which it is directly proportional to the W, if g is lower on the Moon than on Earth, then W is lower on the Moon than on Earth.

When light travels from air to water at an angle which of the following happens? a) The light slows down and it changes directio
beks73 [17]

Answer:

b) The light slows down and it changes direction towards the perpendicular.

Explanation:

Light travels at different speed in different mediums.

Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.

Or ,

n = c/v.

Light travels at a slower speed in water as compared to air because there are more number of interfering molecules in the path of the light in case of water as compared to liquid.

<u>When a light travels from lower denser medium say water to higher denser medium say water, it bends towards the perpendicular as its speed reduces in that medium.</u>
