A steel pot has a bottom with a cross sectional area of .1m2 and has a thickness of 1cm. The pot is filled with boiling water an
jenyasd209 [6]

Answer:

840000 J/min

Explanation:

Area = A = 0.1 m²

Bottom of pot temperature = 200 °C

Thermal conductivity = k = 14 J/sm°C

Thickness = L = 1 cm = 0.01 m

Temperature of boiling water = 100 °C

From the law of heat conduction

Q = kAΔT/L

⇒ Q = 14×0.1×(200-100)/0.01

⇒ Q = 14000 J/s

Converting to J/minute

Q = 14000×60 = 840000 J/min

∴ Heat being conducted through the pot is 840000 J/min

A boy, standing at point O, is whirling a ball on a string over his head. After several whirls, he lets go of the string and the
Vikki [24]
When a ball is whirled using a string, it is restricted to move only in circular motion because the net force acting on the ball is towards the center of the circle. Hence, the acceleration of the ball is towards the center. But the velocity of ball is tangential to this circular path all the time. When the whirling is stropped, the string becomes slack and tension in the string becomes zero. The ball no more performs circular motion and the ball moves tangentially to the circle in straight line. Therefore, before letting go, velocity was variable. After letting go, velocity becomes constant.

If you were to compare three stars with the same surface temperature, with one star being a giant, another a supergiant, and the
Fudgin [204]

Answer:

Radii of Super giant > giant > main sequence star.

Explanation:

A star becomes a giant after all the hydrogen available for fusion, in a main sequence star is depleted and its outer shell of the star expands.

Super giant and giant stars are very large in size compared to a main sequence star. For example, if a giant star has 20 times the diameter of main sequence star, the super giant's diameter is almost 300 times or even more than a main sequence star.  

Most of the stars are main sequence stars. After a star has spent a few million or even a few billion years as a main sequence star, it becomes a giant and a super giant star. These are the later stages of development of development of the main sequence star. Giant and super giant phase of a star's life is very short compared to the main sequence star.

Sound travels fastest in _____. solids liquids cold gases warm gases
agasfer [191]
Sound travels fastest through a solid, because the molecules are most tightly packed together in a solid, helping the sound waves jump from one molecule to another faster. Sound travels second fastest through a liquid because the molecules are packed together second most, and sound travels slowest through gasses. 

Sound travels fastest in solids, slower in liquids, and slowest in gasses.
