Altered means to change something.
Answer: C) By collecting run off during the rainy season for future irrigation increases the agricultural production
Explanation:
Water harvesting is a process of collection of rain water by using special water storing systems. This water storage practice helps during the scarcity of water like in dry summer seasons and in conditions of drought. Such water can be treated with filters to make it potable for drinking. But generally the water is used for the purpose of irrigation in the agricultural field and household sanitary requirements.
On the basis of the above description, By collecting run off during the rainy season for future irrigation increases the agricultural production is the correct option.
Answer:
-2 C
Explanation:
charge of an electron = -
therefore charge of 1.25 x 
electrons = 
= -2 C
Answer:
Explanation:
It is given that,
The radius of the solid sphere, R = 50 cm = 0.5 m
Charge on the sphere, 
We need to find the magnitude of the electric field r = 10.0 cm away from the center of the sphere. The electric field at point r away form the center of the sphere is given by :
So, the electric field 10.0 cm away from the center of the sphere is 
. Hence, this is the required solution.
PE = (250) (30) (9.81) = 73575J
I used to use 9.81 as acceleration due to gravity. The answer might be different from what you expect
