Question

please answer this question of Physics

Answer 1

Explanation:

Total pressure at depth h below the water surface

=atmosphericpressure+waterpressure.

Let atmospheric pressure be P. Then, total pressure

=1.5 p

$1.5p \: = p + hdg = hdg \: = 0.5p$

$h = \frac{0.5p}{dg} = \frac{0.5 \times {10}^{5} {nm}^{ - 2} }{ {10}^{3} {kgm}^{ - 2} \times 9.8 {ms}^{ - 2} }$

$\frac{5 \times {10}^{5} }{ {10}^{3} \times 98 } m = \frac{500}{98} m = 5.1m \:$

dear user, hope it helps you

Answer 2

⭐Answer⭐

Total pressure at depth h below the water surface

= atmospheric pressure + water pressure.

Let atmospheric pressure be p. Then, total pressure = 1.5 p

Therefore 1.5 p = p + hdg

= Hdg = 0.5 p

= h = 0.5 p / dg = 0.5 * 10^5 =Nm^-2 / 10^3 kgm * 9.8 ms

= 5 * 10^5 / 10^5 * 98 m

= 500 / 98 m

= 5.1 m

Hope it helps❤
