Sample Response: When there is less rainfall, land, which is part of the geosphere, becomes dry. When there is not enough water,

plants will not get the nutrients they need from the soil and animals will not get enough water, and they will die. Both plants and animals are part of the biosphere. Less precipitation would also mean less water in lakes and groundwater, parts of the hydrosphere, and less evaporation. The atmosphere may also be affected due to less water vaporWhich ideas did you include in your answer? Check all that apply.

The length of a certain wire is kept same while its radius is doubled. what is the change in the resistance of this wire?
kaheart [24]
The resistance of a wire is given by
R= \frac{\rho L}{A}
where \rho is the resistivity of the material, L the length of the wire and A its cross-sectional area. 

In the problem, \rho and L remain the same, while A changes because the radius changes. The area is given by:
A=\pi r^2
This means that if we double the radius (2r), the area becomes
A_{new}= \pi (2r)^2 = 4 \pi r^2 =4A
And therefore, the new value of the resistance is
R_{new} =  \frac{\rho L}{4 A}= \frac{1}{4}R

So, when the radius is doubled, the resistance becomes \frac{1}{4} of its original value.

A tungsten wire has resistance R at 20°C. A second tungsten wire at 20°C has twice the length and half the cross-sectional area
Bad White [126]
The resistance is 4 times the resistance of the first wire. the formula is R = p*l/A with p being resistivity, l length and A area. So if you double length and half area, which botv result in more resistance, you get p*2/0.5 or 4 (p can be abandoned because it is the same. We take standard length and area as 1)
