Answer:
0.64 m from the first charge
Explanation:
Force is given by


These forces are equal

The distance that charge should be placed is 0.64 m from the first charge
“Gaining or losing electrons has no impact on the number of protons and neutrons an atom has, which is another way of saying that the mass number is not affected by changes in the net charge.”
Given:
Water, 1.5kg at boiling point
Required:
Heat required to vaporize at boiling
point
Solution:
Water at boiling point is at
100degrees Celsius
Changing it into Kelvin, just dd
273 to 100 = 373 K
H
= mCpT
H
= (1.5kg)(4.184kJ/kg-K)(373K)
<span>H =
2340.9kJ</span>
Adaptation is when a living thing changes its behavior to survive in its surroundings.
