What happens inside an empty tank when it is filled with air?

Physics

Answer:

pressure is created at the wall's surface

Explanation:

When air is filled in an empty tank, air molecules try to spread through out the tank. The gas molecules  has random and continues motion due to which they possess kinetic energy. Due to this energy air molecules continuously strike with the wall of the tank and apply force  on the wall of  tank due to which reaction force is applied on air  molecule In this way pressure is created on tanker's walls and it  becomes hot.

An auditorium measures 35.0 m x 30.0 m x 5.0 m. The density of air is 1.20 kg/m^3. (a) What is the volume of the room in cubic f
Ksenya-84 [330]

Answer:

(a) 1852259 ft^3 (b) 489085.47 pound

Explanation:

We have given auditorium measures 35 m×30 m×5 m

We know that 1 meter = 3.28 feet

So the measure of auditorium = 35×3.28 feet ×30×3.28 feet× 5×3.28 feet

(a) So the volume of the auditorium =35\times 3.28\times 30\times 3.28\times 5\times 3.28=185259.648ft^3

Density is given as d=1.20kg/m^3  

(b) weight of air  = volume × density =185259.648\times 1.2=222311.577kg

We know that 1 kg = 2.20 pound

So 222311.577 kg =222311.577×2.20=489085.47 pound

A 34,000-lb airplane lands on an aircraft carrier and is caught by an arresting cable. The cable is inextensible and is paid out
Firlakuza [10]

Answer:

  F = 153637 lb

Explanation:

Let's use the kinematic equations to find the airplane's braking speed

       v² = v₀² + 2 a d

The final speed is zero

       a = - v₀² / 2d

Let's reduce the magnitudes

       v₀ = 110 mi / h (5280 ft / 1 mile) (1 h / 360 s) = 161.33 ft / s

       a = -161.33²/2 90

       a = -144.60 ft / s²

Now we can use Newton's second law to find the tension

       F = m a

       F = (34000/32) 144.60

      F = 153637 lb

Describe a situation where kinetic energy is converted into potential energy
siniylev [52]
1. A spring or elastic can be stretched to store energy as it wants to return to rest.

2. Gravitational every can be is stored by moving a ball against gravity when lifted then released when bounced.

3. Separating two charged plates will store energy as the plates want to return to their original position.

An object is moving east with a constant speed of 30 m/s for 5 seconds. What is the object’s acceleration?
Shtirlitz [24]

Answer:

6 m/s²

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 30 m/s

Time (t) = 5 s

Acceleration (a) =..?

Acceleration is defined mathematically as:

Acceleration (a) = Velocity (v) /time (t)

a = v /t

With the above formula, we can obtain the acceleration of the object as follow:

Velocity (v) = 30 m/s

Time (t) = 5 s

Acceleration (a) =..?

a= v/t

a= 30/5

a = 6 m/s²

Therefore, the acceleration of the object is 6 m/s² due East.
