Answer:density
Explanation:
At the bottom, deep bodies of water always measure because at that temperature water has it highest density .
In water bodies like lake warm water rises up due to convection and at higher depths there is cold water, which is found to be at highest density of water.
When water molecules acquired heat energy it become widely spread at the same volume and thus posses low density but at low temperature water molecule occupy less space therefore posses maximum density at
It might be a or d not too sure though
Well it determines on how much magnetism a material has.
The sun's source of energy is know as nuclear fusion (means to fuse) this process has a small nuclei atoms that join together to form a large nucleus. The result of this process is released energy. The fusion of hydrogen into helium in the sun makes a large amount of energy and this is known as the sun's energy source.
The theories that scientist proposed about the source of the sun's energy was that the sun burned fuel to generate its energy and that gravity was causing the sun to shrink slowly and have its energy released. Also both of these theories were disproved.

Answer:
Explanation:
Given
mass of climber
Distance between rock and cliff=48.6 m
mass of rock
let T be the tension in the rope
Thus ------1
where a is the acceleration of system
Also for Rock
------2
From 1 & 2 we can say that
g+a=19.303 a
g=18.303 a
Thus climber is decelerating with
time to cover 48.6 m
t=13.47 s
