True statements that reflect why infants experience more fluid and electrolyte changes are that dehydration can upset the balance of electrolytes in an infant or child and the newborn is at risk of excessive water loss and hypernatremia as the result of high evaporative water loss through the skin.
As infants are not used to the environment around , they are more sensible towards problems such as Dehydration because of fast metabolism.
Dehydration can upset the balance of electrolytes in an infant or child. Children are especially vulnerable to dehydration due to their small size and fast metabolism, which causes them to replace water and electrolytes at a faster rate than adults.
Infants are particularly prone to the effects of dehydration because of their greater baseline fluid requirements (due to a higher metabolic rate), higher evaporative losses (due to a higher ratio of surface area to volume), and inability to communicate thirst or seek fluid.
The newborn is at risk of excessive water loss and hypernatremia as the result of high evaporative water loss through the skin, insensible water loss (IWL), as well as decreased capacity to concentrate the urine.

Answer:
1.been both -ve charged or both +be charged particles
2. 3.52mC
Explanation:
For the charge particle to cause an extension or movement of the string from its unrestrained position they would have been both -ve charged or both +be charged particles that's because like charges repel.
Now the Force sustain by the extended string is
F = Ke;
Where K is the force constant of the string, 320 N/m
e is the extension,0.033 m
F = 320 × 0.033 =10.56N
2.But according to columns law of charge;
F = kQ1 Q2
But Q1=Q2{ since the charge are of the same magnitude}.
Hence F = KQ^2
Where K is columns constant =9×10^9F/m
Hence Q=√F/K
Q= √10.56/9×10^9
=3.52×10^-3C
= 3.52mC
Answer:
a) 
b) No
Explanation:
A) Because the electron is affected by an acceleration force in this case by the electric field, we can use the formulas of 2-dimension movement.
We will assume the electron missed the upper plate, so we need to calculate the time to travel all the way through the plate, that is:
so:
the electron experiences an accelerated motion in the vertical direction, so we can obtain the acceleration of the electron:
so:
now we can use the relation:
Now we can calculate the electric field:
B) Because the proton has the same charge but positive it will go in the opposite direction, so because we assume the electron didn't touch the plate, the proton won't.
<h2>
Answer:distance and force</h2>
Explanation:
Let 
be the work done.
Let 
be the force applied.
Let 
be the displacement of the object.
Workdone by a object is defined as the dot product of force and displacement.
Since distance is the magnitude of displacement when force and displacement are in a same direction,
So,work done depends on force applied and distance.
The term that is being described by the definition given above is called PEER REVIEW. What is done in the peer review is that, the experiment is being evaluated or checked first by people who are also working on the same field. So the answer for this is option C.
