Answer : The heat your body transfer must be, 25.1 kJ
Explanation :
Formula used :
or,
where,
Q = heat = ?
m = mass of water = 500.0 g
c = specific heat of water = 
= initial temperature = 
= final temperature = 
Now put all the given value in the above formula, we get:
Therefore, the heat your body transfer must be, 25.1 kJ
The net force is the sum of all of the forces that cancelled out to zero. Hence, option D is correct.
<h3>What is force?</h3>
The pushes or pulls on an object with mass causes it to change its velocity.
The net force is the vector sum of all forces acting on an object. Force is a vector quantity.
Two forces of equal magnitude when acting on an object in opposite directions will cancel out each other.
As a result net force is equal to 0. The word net here shows the total force acting on the object.
Hence, option D is correct.

Answer:
3 protons and also 3 electrons
Explanation:
z=p=e
Molarity is defined as the number of moles of solute in 1 L of solution
mass fo KCl in the solution is - 5.0 g
number of moles of KCl - 5.0 g/ 74.5 g/mol = 0.067 mol
number of moles of KCl in 100 mL - 0.067 mol
therefore number of KCl moles in 1 L - 0.067 / 100 mL x 1000 mL = 0.67 M
molarity of KCl is 0.67 M
