If the object has a lower density than water, it will float.
If the object has a higher density than water, it will sink.
The age of a man whose normal blood pressure measures 123 mm of hg

<h3>What is Quadratic equation ?</h3>
A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = a
+ bx + c, where a, b, and c are numbers and a cannot be 0
P(A) = 0.006 
- 0.02a + 120
123 = 0.006- 0.02a + 120
0=0.006 - 0.02a - 3
you can use the quadratic equation formula to solve for the man's age.
A = (-b ± (
) ) / (2a)
A = (0.02 ± 
/ (2*0.006)
A = (0.02 ± 
) / 0.012
A = 9 , -5.67
Age of the man will be 9 years

Answer:
By decreasing the surface area exposed to the air. Vertical body position instead of horizontal.
Explanation:
So the terminal velocity formula is as follows.
v = sqrt[(2*m*g)/(p*A*c)]
m = mass
g = 9.81 m/s^2
p = density of air
A = surface area of object
c = Drag coefficient
So the only thing you can change in mid-air is surface area.
The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
<h3>Why does water change in volume?</h3>
Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.
One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.
As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
