Explanation:
The citric acid in the lemon acts as an electrolyte, a solution that conducts electricity. The zinc nail sheds electrons as electrically charged ions into the acid (a process called “Oxidation” because the material loses electrons). ... The average lemon output is . 9 volts at .
Complete Question
If you are lying down and stand up quickly, you can get dizzy or feel faint. This is because the blood vessels don’t have time to expand to compensate for the blood pressure drop. If your brain is 0.4 m higher than your heart when you are standing, how much lower is your blood pressure at your brain than it is at your heart? The density of blood plasma is about 1025 kg/m3 and a typical maximum (systolic) pressure of the blood at the heart is 120 mm of Hg (= 0.16 atm = 16 kP = 1.6 × 104 N/m2).
Answer:
The pressure at the brain is 
Explanation:
Generally is mathematically denoted as

Substituting
for
(the density) ,
for g (acceleration due to gravity) , 0.4m for h (the height )
We have that the pressure difference between the heart and the brain is

But the pressure of blood at the heart is given as

Now the pressure at the brain is mathematically evaluated as



Answer:
The magnitude of the electric field is
in the r direction.
Explanation:
The equation of the electric field is given by:

Where:
- k is the Coulomb constant is

- q is the charge
- r is the distance from A to q
Therefore, the magnitude of the electric field is
in the r direction.

Force applied
Explanation:
An object will remain at its state of rest unless a non zero for act on it
Answer:
Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance and not an "end-point."
