Explanation:
The biosphere is the portion of the earth where all living organisms can be found.
The hydrosphere refers to the water on the earth crust.
- If there were no hydrosphere, life would not have evolved. Liquid water is a major component of all life. It is essential for metabolic processes in both plant and animals and a host of other activities.
- The hydrosphere provides water that is a major component of the soil. Plants grow on the soil. Soil water is one of the most important component of the soil.
- The hydrosphere made the earth a unique planet where life can be domiciled.

Yes, if weather was hot you need more fluids in your body due to the sweat pores needing to cool you down.
<span>Electric field is proportional to q/d^2, where q is the magnitude of the charge and d is the distance. Since all the given units are identical, we can just compare their relative magnitudes without calculating for the exact values.
A) 3/(0.4)^2 = 18.75
B) 1.5/(0.2)^2 = 37.5
C) 6/(0.4)^2 = 37.5
D) 3/(0.2)^2 = 75
Therefore, choice D has the largest electric field of all.

Answer:
Explanation:
30 km/h b. 60 km/h c. 15 km/h d. 2 km/h. The answer is 15km/h. The rate will be the same. 30km / 2hr = _km / hr. By the law of equivalent fractions ...
Explanation:
It is given that,
Number of turns, N = 200
Area of cross section, A = 8.5 cm²
Magnetic field is directed out of the paper and is, B = 0.06 T
The magnetic field is out of the paper decreases to 0.02 T in 12 milliseconds. We need to find the direction of current induced. The induced emf is given by :
Since, 
I is the induced current
According to Lenz's law, the direction of induced current is such that it always opposes the change in current that causes it.
Here, the field is directed out of the plane of the paper, this gives the induced current in counterclockwise direction.
