Answer:
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.
Explanation:
A person is submerged of about 97.9%.
The average density of the human body is given as 979 kg/ m³.
<h3>Define Law of floatation.</h3>
Law of floatation can be defined as the volume of the liquid displaced when a body floats on the liquid surface is equal to the body submerged in the water.
As body has the stable equilibrium state, the buoyancy of the fluid will be equal to the weight.
Weight of the body floating = Weight of the body immersed in fluid
Law of floatation = Density of the floating object / density of fluid
As fluid is the freshwater here, the density of fluid will be 1000 kg/ m³.
= (979 kg/ m³) / ( 1000 kg/ m³)
= 97.9 %
A person is submerged when floating gently in fresh water about 97.9%.

Answer:
b)
Explanation:
Let the amplitude of SHM is given as A
so the total energy of SHM is given as
now we know that
a)
kinetic energy is given as
here
so now we have
now its fraction with respect to total energy is given as
b)
Potential energy is given as
so we have
so fraction of energy is given as
1.) temperature change, 2.) color change, 3.) gas formation
If the acceleration was constant, then it would be the same as the average acceleration over the 10 second interval:
