What is consistency paradox

Mumz [18]

Answer:

Consistency paradox is the observation that a human being’s personality tends to remain the same over time, while their behavior can change in different situations.

Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.

Which situation has the greatest pressure? A. Atmospheric pressure at sea level, equal to 1.01 X 105 N/m2 B. The pressure that a

Alexeev081 [22]

Answer:

The correct option is B

Explanation:

In part A pressure is given as $1.01*10^5 N/m$

In Part B we can calculate the pressure using the formula

$P = \frac{F}{A}$

Where F is the force which in this case is weight which can be obtained as follow

W = Mg

Substituting 70kg for M and $9.8m/s^2$ for g

$W = 70 *9.8$

$=686N$

A is the area with a value $50cm^2 = \frac{50}{10000} = 5.0*10^{-3}m^2$

So substituting into the above equation

$P = \frac{686}{5.0*10^{-3}}$

$= 1.37 *10^5 N/m^2$

for part c

A $= 22*28 cm^2= \frac{22*28}{10000}m^2$

$=6.16*10^{-2}m^2$

F $= 2.5 * 9.8$

$= 24.525N$

Therefore $P = \frac{24.252}{6.16*10^{-2}}$

$= 298 N/m^2$

From this we see that the value of P for part B is the greatest
