Because a paper clip is type of a metal and magnets and paper clip get pulled to each other.
Answer:

Explanation:
From the question we are told that
The hydraulic conductivity is 
The effective matrix potential 
The intensity of rainfall is 
The runoff rate 
Generally the run off rate is mathematically represented as

Here t is the amount of runoff generated
=> 
=> 
converting to minutes

The answers is
D. The acid creates cracks in the rocks, which
allow air to circulate through the rock,
causing it to weather
Explanation:
It is given that, the metal with the highest melting temperature is tungsten which melts at around 3400 K, T = 3400 K
We need to find the wavelength of the peak of the black body distribution for this temperature. It can be calculated using Wein's displacement law as :

k is the constant,



or

The wavelength of infrared is from 700 nm to 1 mm. So, the lies in infrared region of the spectrum. Hence, this is the required solution.
