How to calculate depth of sea whan a ship receives sound produced by its fathometer after 3.5 second

HACTEHA [7]

Answer:

2600 m

Explanation:

A fathometer produces a sound wave and then detects the echo. It takes 3.5 seconds for the echo to reach the ship, so that means it takes half the time (1.75 seconds) to reach the ocean floor.

The speed of sound in seawater is approximately 1500 m/s, so the depth of the ocean at that point is:

d = 1500 m/s × 1.75 s

d = 2625 m

Rounding to two significant figures, the depth is approximately 2600 m.

A Pitot-static probe is used to measure the speed of an aircraft flying at 3000 m. If the differential pressure reading is 3300

adell [148]

Answer:

v = 306.76 Km/h

Explanation:

given,

height of the aircraft = 3000 m

differential pressure reading = 3300 N/m²

density of air = 0.909 Kg/m³

speed of aircraft = ?

Assuming the air flowing above air craft is in-compressible, irrotational and steady so, we can use Bernoulli's equation to solve the problem.

using Bernoulli's equation

$\dfrac{v^2}{2} = \dfrac{\Delta P}{\rho}$

where ρ is the density of the air at 3000 m

$v= \sqrt{\dfrac{2 \times \Delta P}{\rho}}$

$v= \sqrt{\dfrac{2 \times 3300}{0.909}}$

$v = \sqrt{7260.726}$

v = 85.21 m/s

$v= 85.21 \times \dfrac{3600}{1000}$

v = 306.76 Km/h

Which graph represents the solution set of the system of inequalities?<br><br> {−2x+y≤4y>x+2

Jet001 [13]

Answer:

The fourth graph is the answer

Explanation:

We have inequalities

$-2x+y\leq 4$ $\rightarrow y\leq 2x+4$

$y>x+2$

For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of $y>x+2$ and below the graph of $y\leq 2x+4$ . The shaded region in the fourth graph satisfies these conditions.

<em>Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region. </em>

P.S: the graph of the inequality $y>x+2$ is dashed because $y$ is "greater than" and not "equal to" $x+2$ , so this indicates that the values on the line $y=x+2$ are not included. And the graph of the inequality $y\leq 2x+4$ is a solid line because $y$ is "less than or equal to" $2x+4$ , so we are including the values on the line $y=2x+4$ , and that's why it's solid.
