El interior de un tanque que contiene agua, tiene una presión manométrica de 300 kPa. ¿Qué profundidad tiene el tanque de agua?
zmey [24]

Respuesta:

30,6 metros

Explicación paso a paso:

Dado :

Presión = 300 Kpa

Usando la fórmula que relaciona la presión y la profundidad:

Presión = profundidad * aceleración debida a la gravedad * densidad del agua

Densidad del agua = 1000 kg / m³

Presión = 300Kpa = 300 * 10 ^ 3 Pa

300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000

300000 = profundidad * 9800

Profundidad = 300000/9800

Profundidad = 30,612

Profundidad = 30,6 m

Solve for ppp. 16-3p=\dfrac23p+516−3p= 3 2 ​ p+516, minus, 3, p, equals, start fraction, 2, divided by, 3, end fraction, p, plus
Ksivusya [100]

Given:

The given equation is:

16-3p=\dfrac{2}{3}p+5

To find:

The value of p.

Solution:

We have,

16-3p=\dfrac{2}{3}p+5

Multiply both sides by 3.

3(16-3p)=3\left(\dfrac{2}{3}p+5\right)

48-9p=2p+15

Isolating the variable terms, we get

48-15=2p+9p

33=11p

Divide both sides by 11, we get

\dfrac{33}{11}=p

3=p

Therefore, the required solution is p=3.

Find the value of m .​
kondor19780726 [428]

Step-by-step explanation:

if the 2 matrices are inverse, then their product must be the identity matrix

1 0

0 1

so,

m×3 + 2×-7 = 1

7×3 + 3×-7 = 0

m×-2 + 2×m = 0

7×-2 + 3×m = 1

that means we have to solve only

3m - 14 = 1

3m = 15

m = 5

Part A: What does 0 represent in this situation? (3 points)
vampirchik [111]

Using the concept of number line, the solution to the questions posed are :

  • <em>Pool</em><em> </em><em>surface</em><em> </em>
  • <em>The</em><em> </em><em>height</em><em> </em><em>of</em><em> </em><em>slide</em><em> </em><em>is</em><em> </em><em>12</em><em> </em><em>meters</em><em> </em><em>above</em><em> </em><em>the</em><em> </em><em>pool</em><em> </em><em>surface</em><em> </em>
  • <em>The</em><em> </em><em>level</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>bottom</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>pole</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>marked</em><em> </em><em>as</em><em> </em><em>-</em><em>3</em>

The pool surface would be treated as sea level surface, such that, position below are marked as negative and position above are marked as positive.

  • Therefore, the surface of the pool is <em>marked</em><em> </em>as the sea level position, 0.

  • Since the slide is above the surface of the pool, it's value will the positive. Hence, the height of the slide is 12 feets.

  • The marked position is below the <em>pool</em><em> </em><em>surface</em><em>,</em><em> </em>hence, it will take up a negative value of - 3 feets.
