solniwko [45]

Starting from rest, the plane travels a distance

<em>x</em> = 1/2 <em>at</em>²

with acceleration <em>a</em> after time <em>t</em>. In this instance, it travels

<em>x</em> = 1/2 (3.20 m/s²) (32.8 s)²

<em>x</em> ≈ 1720 m

How fast does water flow from a hole at the bottom of a very wide, 3.2 m deep storage tank filled with water
Nezavi [6.7K]

Answer:

the velocity of the water flow is 7.92 m/s

Explanation:

The computation of the velocity of the water flow is as follows

Here we use the Bernouli equation

As we know that

V_1 = \sqrt{2g(h_2 - h_1)}\\\\=\sqrt{2g(\Delta h)}  \\\\= \sqrt{2\times9.8\times3.2} \\\\= \sqrt{62.72}

= 7.92 m/s

Hence, the velocity of the water flow is 7.92 m/s

We simply applied the above formula so that the correct value could come

And, the same is to be considered

DerKrebs [107]

Answer:

A naturally radioactive element of the actinide metals series. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, Plutonium dioxide is formed when plutonium or its compounds (except the phosphates) are ignited in air, and  Plutonium oxide fired at temperatures 600 C is difficult to rapidly.

The density (mass/volume) of aluminum is 2.70 mc016-1.jpg 103 kilograms per cubic meter (kg/m3). What is the mass of an aluminum
Masja [62]
The answer is 4.05 × 10³ kg

The density (D) is a quotient of mass (m) and volume (V) of a substance:
D = m/V

Step 1. Calculate the volume o
We have:
D = 2.70 × 10³ kg/m³
V = 1.50 m³
m = ?

D = m/V
m = D * V
m = 2.70 × 10³ kg/m³ × 1.50 m³ = 4.05 × 10³ kg
