Because the silt (dirt particles) in muddy water eventually settles out, the muddy water is a __suspension__ .
Answer:
Density of rock piece = 2.7 g/cm³
Explanation:
Given:
Volume of rock piece = 18 cm³
Mass of rock piece = 48.6 gram
Find:
Density of rock piece
Computation:
We know relation between density, mass and volume,
Density = Mass / Volume
Density of rock piece = Mass of rock / Volume of rock
Density of rock piece = 48.6 / 18
Density of rock piece = 2.7 g/cm³
Answer:
1100Joules
Explanation:
Workdone = force x distance
Force= 500N
Distance = 2.2m
So, workdone = 500 x 2.2
= 1100Joules
Answer:
1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.
2. The image cannot be projected onto a screen also.
3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.

Because Mars is further from the sun than Earth is, thus the gravitational pull is not as great on Mars as it is on Earth, making us lighter :)
