The extra energy from the vapor(a gas)leaves the vapor when it becomes dew(a liquid)and goes into the surrounding area.

Answer:

The average current density at the position of the area.

Explanation:

Current density is the vector whose magnitude is electric current in the cross sectional area. Current density is vector quantity which is measured in amperes. The average current density is dependent on the electric current flow. It has perpendicular direction of flow and scalar magnitude.

a. The speed of the tsunami at ocean depth of 8000 m is 1,019.66 km/h.

b. The speed of the tsunami at ocean depth of 3500 m is 660.75 km/h.

c. The speed of the tsunami at ocean depth of 70 m is 89.66 km/h.

d. The speed of the tsunami at ocean depth of 5 m is 30.625 km/h.

<h3>Speed of the tsunami at the given depths</h3>

The speed of the tsunami is calculated from method of extrapolation or interpolation as shown below;

<h3>Speed at 8000 meters</h3>

8000 m -------- ?

7000 m -------- 943 km/h

4000 m -------- 713 km/h

(8000 - 7000)/(7000 - 4000) = (? - 943)/(943 - 713)

0.3333 = (? - 943)/230

230(0.3333) = ? - 943

76.66 = ? - 943

? = 1,019.66 km/h

<h3>Speed at 3500 m</h3>

4000 m ---------- 713 km/h

3500 m ---------- ?

2000 m ----------- 504 km/h

(4000 - 3500)/(4000 - 2000) = (713 - ?) / (713 - 504)

0.25 = (713 - ?) /209

0.25(209) = 713 - ?

52.25 = 713 - ?

? = 660.75 km/h

<h3>Speed at 70 m</h3>

200 m ------ 159 km/h

70 m --------- ?

50 m ------- 79 km/h

(200 - 70)/(200 - 50) = (159 - ?)/(159 - 79)

0.8667 = 159 - ? / 80

80(0.8667) = 159 - ?

69.336 = 159 - ?

? = 89.66 km/h

<h3>Speed at 5 meters</h3>

50 m ------- 79 km/h

10 m --------- 36 km/h

5 m ---------- ?

(50 - 5)/(50 - 10) = (79 - ?)/(79 - 36)

1.125 = 79 - ?/43

43(1.125) = 79 - ?

48.375 = 79 - ?

? = 30.625 km/h

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
