Answer:
The magnitude of the electric force on a protein with this charge is 
Explanation:
Given that,
Electric field = 1500 N/C
Charge = 30 e
We need to calculate the magnitude of the electric force on a protein with this charge
Using formula of electrostatic force

Where, F = force
E = electric field
q = charge
Put the value into the formula


Hence, The magnitude of the electric force on a protein with this charge is 
Individuals have different traits because they are not twins so they should not be alike also because people have different genes witch would give them different traits. For example not every individual has blonde hair and blue eyes because they did not inherit those traits.
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.
The force is known as electrostatic force (or electric force)
