Does blowing room-temperature air over an ice block heat it because of convection

Physics

Mandarinka [93]3 years ago

Yes

Explanation:

Blowing a room-temperature air over an ice block will heat it because of convection.

Convection is one of the heat transfer modes that occurs in fluids.

  • In convection, a hot and lighter fluid replaces a denser and cold fluid.
  • It involves the actual motion of the particles of the medium.
  • In this analogy, the blowing room-temperature is hot and lighter.
  • It will replace the air close to the ice block body that is cold and denser
  • As the hot air comes near the ice block, it loses some of its heat and warms the cold ice.
  • In turn, the air becomes colder and moves away.
  • This is simple convection in action.

Naily [24]

Answer:

"0.049 W" is the correct answer.

Explanation:

According to the given question,

r = \sqrt{(3.5)^2+(2.5)^2}

  =\sqrt{8.5}

SL=85

As we know,

⇒  SL=10 \ log(\frac{I}{I_o} )

     85=10 \ log(\frac{I}{10^{-12}} )

      I=3.162\times 1^{-4} \ W/m^2

Now,

⇒  P_{front} = I(2\pi r^2)

               =(3.162\times 10^{-4})(2\pi\times 18.5)

               =0.0368 \ W

               =0.75 \ P

or,

                =0.049 \ W

A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.12 g coins stacked over the 24.2 cm mark, th
pashok25 [27]

Answer:

The mass of the meter stick is  1.66054054054g

Explanation:

Here since the meter stick is in equilibrium position its net torque and net force should be equal to zero

      Since at the begging the meter stick is balanced at center of the meter stick that means its center of mass should be present at 50.0cm

Now lets consider the later case where stick is balanced by two 5.12 g coins .

Here torque due to two coins = t_{c} = 5.12\times(27.8-24.2)\times2\times9.8

  Torque due to weight of meter stick =  t_{m} =  m\times(50-27.8)\times9.8

  where m = mass of the meter stick

    Here t_{c} = t_{m}.

Upon equating we will be getting mass of the meter stick =1.66054054054g
