Which of the following processes DOES NOT occur during the convective transfer of heat within a container of air? Group of answe

r choices The cooler portion of the air surrounding a warmer part exerts a buoyant force on it. The flow of air molecules results in a flow of heat. As the warmer part of the air moves, it is replaced by cooler air that is subsequently warmed. A continuous flow of warmer and cooler parts of air is established. The volume of a warmed part of the air is reduced and its density increases.

The volume of a warmed part of the air is reduced and its density increases.

Explanation:

In a convective form of heat transfer, the volume of a warmed part of air is not reduced and its density does not increase.

During convection, heat causes the warm part of the air to expand and its volume increases. When volume increases, density is reduced.

  • Convection is a form of heat transfer that involves the actual movement of particles of the medium.
  • It usually occurs in fluids i.e gases and liquids.
  • In convection, the cold part exerts a buoyant force on the warmer air below and causes it to rise.
  • As the warmer part is rising the cooler part replaces it and a convective cell is formed in the process.

garri49 [273]

Answer:

The depth is 5.15 m.

Explanation:

Lets take the depth of the pool = h m

The atmospheric pressure ,P = 101235 N/m²

The area of the top = A m²

The area of the bottom =  a m²

Given that A= 1.5 a

The force on the top of the pool = P A

The total pressure on the bottom = P + ρ g h

ρ =Density of the  water = 1000 kg/m³

The total pressure at the bottom of the pool =  (P + ρ g h) a

The bottom and the top force is same

(P + ρ g h) a = P A

P a +ρ g h a =  P A

ρ g h a =  P A - P a

h=\dfrac{P ( A-a)}{\rho g a}

h=\dfrac{P ( 1.5 a-a)}{\rho g a}

h=\dfrac{P ( 1.5- 1)}{\rho g}

h=\dfrac{101235 ( 1.5- 1)}{1000\times 9.81}\ m

h=5.15 m

The depth is 5.15 m.

Aluminum has an atomic number of 13,  so it has 13 protons. In its natural state, it does not have a charge,  so it has an equal amount of electrons, 13. The atomic mass of aluminum is approximately 27. Since protons and neutrons make up that mass, and each of the particles are around 1 atomic mass unit, if there are 13 protons, then there are 27-13 neutrons, or 14 neutrons. So the first answer choice is correct.

A spaceship with a constant speed of 0. 800c relative to earth travels to a star that is 4. 30 light-years from earth. how much
Strike441 [17]

Main Answer:

Given  speed of spaceship v = 0.8c = 0.8 * 3 x 10^8 m/s

Speed of spaceship v = 2.4 x 10^8 m/s

Distance need to be travelled d = 4.3 light years

we know that 1 light year  = 9.461 x 10^15 m

Distance need to be travelled d = 4.3 x 9.461 x 10^15

d = 40.6823 x 10^15 m

Time taken for the trip would elapse on a clock on board the spaceship

t = distance/ velocity

t = 40.6823 x 10^15 / 2.4 x 10^8

t = 16.95 x 10^7 sec

t = 4.71 x 10^4 hours

Explanation:

What is light year?

Light year is defined as the distance travelled by the light in one year. In a year, light travels through 300000 km per sec in the interstellar space.
