Explanation:
The accurate answer is
The psychiatrist that <span>believed the environment was more important to a child's intellectual development than biology was "D" </span>Sigmund Freud.
The electrostatic force is directly proportional to the product of the charges, by Coulomb's law.
F α Qq
If the charges are now half the initial charges:
<span>F α (1/2)Q *(1/2)q
</span>
F α (1/4)Q<span>q
The new force when the charges are each halved is (1/4) the first initial force experienced at full charge.</span>
Answer: The ice absorb 6671.1 kJ of thermal energy.
Explanation:
The conversions involved in this process are :


Now we have to calculate the enthalpy change.

where,
= enthalpy change = ?
m = mass of ice = 20.0 kg =
(1kg=1000g)
n = number of moles of ice= 
= enthalpy change for fusion = 6.01 KJ/mole = 6010 J/mole
Now put all the given values in the above expression, we get

(1 kJ = 1000 J)
Therefore, the enthalpy change is, 6671.1 kJ
