Explanation:
The electric force between charges is given by the formula as follows :

k is electrostatic constant
r is distance between charges
Here, charges are equal and opposite. So,

It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :
- Increasing the magnitude of charges
- Decreasing the distance between charges.
Answer:
You could conclude the 2nd fact
Explanation:
The struggles were that women weren't really supposed to get an education back then, people called intelligent women witches and wouldn't teach them things. Those were the main struggles.

I would say the answer is D
A hygrometer is an instrument used to measure relative humidity. ... To determine the relative humidity, the temperatures are taken from the dry-bulb thermometer and the temperature difference between the wet and dry bulb thermometers.
hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers -- a dry and wet bulb psychrometer and a mechanical hygrometer.
