Answer 1) : Hydrosphere.
Explanation : The largest sphere on the planet is hydrosphere, which is the combined mass of water found on a planet, available under, and above the surface of a planet, minor planet or natural satellite. It has been estimated that there are 1,386 million cubic kilometers of water on Earth. So, this is the largest sphere on a planet if you are traveling on Earth.
Answer 2) The other parts of the sphere are geosphere, atmosphere and biosphere.
Explanation : Geosphere - This sphere includes all the stuff that make up the crust and the core of the earth. It includes everything natural and lifeless that make up the surface of the earth. Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans.
Atmosphere - The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.
Biosphere - It is also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system, and largely self-regulating.
ANSWER:
300 J
STEP-BY-STEP EXPLANATION:
To know the work required, we must calculate the work in both cases, the difference would be the amount of work necessary for the speed to increase. The work done is the same as the amount of energy increase. The formula for kinetic energy is:
We calculate in each case:
We calculate the difference between the two to find out the work required:
The work required is 300 J
After conversion from cm³ to ml we get 3mili litres.
<h3>What are fundamental units?</h3>
The SI comprises a coherent system of units of measurement starting with seven base units ,which are the second,metre, kilograms,ampere, kelvin, mole and candela. SI unit is a scientific method of expressing the magnitude or quantities of important natural phenomenon.
When measured an object by the help of ruler I get the value 3cm and when I calculated its volume is 3cm³ . After converting it from cm³ to ml we get 3ml .

When light strikes a red object, the light waves of all colors except red are <em>absorbed</em> into the object, and never heard from again. <em> (B)</em>
The only thing left to bounce off of the object into anyone's eye is the waves of red.
