Answer:
serial in which container is filled
Solid -base of container
Liquid- above solid
Gas- above liquid
Explanation:
If any mixture of matter in different state (that solid , liquid or gas )are kept in any container, then substance with higher density will be settled at lowest surface first and similarly the substance with lowest density will be at upper part of container.
In the given container we have to keep solid, liquid and gas
- sold has the highest density,
- gas the lowest density and
- liquid has the density higher than gas but less than solid.
based on this
solid will be at surface of container
above sold will be liquid
above liquid will be presence of Gas
serial in which container is filled
Solid -base of container
Liquid- above solid
Gas- above liquid
Answer: a stone thrown into a lake
Explanation:
The option that exhibits parabolic motion is a stone that is thrown into a lake.
Projectile motion is a form of motion that is seen when a particular object is thrown towards the surface fo the Earth. Such objects are acted upon by gravity.
According to the introduction, why are black holes invisible?
the answer is in the first paragraph :)
"Black holes are invisible because they have so much gravity that nothing escapes. Not even light can escape or bounce off."
hope this helped !
Radius of Earth is given as
now here the height from the surface of earth is same as that of radius
now here the acceleration due to gravity at this height is given as
now the force of gravity on the given object will be
<em>so the force of gravity on it is 1.225 N</em>
