You want the force/area ratio to be the same for both pistons to keep constant pressure. Since 1500/450=3.333, you will need to pick the two sets of dimensions such that (assuming the pistons are rectangular) the product of the pair of dimensions for the 1500 kg piston is 3.333 times the product of the pair of dimensions for the 450 kg piston.
Newton's 3rd law says that for every force there is an equal and opposite reaction force.
So for the force of the hammer hitting the nail, there is a force equal in magnitude exerted back on the hammer by the nail (and is "opposite" because it's in the other direction and on the hammer.)
Answer:
5 Newtons Up and 5 Newtons Right
Explanation:
Treat each force vector as a value and choose the upward and rightward directions to be positive. Downward and Leftward forces will be considered "negative". For the vertical net force we have a positive 10 N upwards and a negative 5 N downwards. The net force in the vertical will be 5 N upwards. In the horizontal we have 10 N to the right and 5 N to the left. The net force in the horizontal will be 5 N to the Right.
It is easier if you split the motion into horizontal and vertical components.

Answer:
0.639 V
Explanation:
The volatge of the cell containing both Ag/AgCl reference electrode and
electrode = 0.693 V
Thus,
E_{anode}=0.197 V
Note: potential of the silver-silver chloride reference electrode (0.197 V)
⇒E_{Cthode}= 0.693+0.197 = 0.890V
To calculate the voltage of the cell containing both the calomel reference
electrode and electrode as follows
Voltage of the cell = 
E_{anode}= calomel electrode= 0.241 V
Voltage of the cell = 0.890-0.241 = 0.639 V
Therefore, the new volatge is = 0.639 V
