Answer:
Aluminium
Explanation:
When a certain amount of heat is supplied to a substance, the temperature of the substance increases according to the equation:
where
is the increase in temperature
Q is the amount of heat supplied to the substance
m is the mass of the substance
C is the specific heat capacity of the substance
Here the four substances have the same mass,
m = 50.0 g
Also, the amount of heat supplied to the 4 substances is the same. This means that their increase in temperature is inversely proportional to their specific heat capacity:
Therefore, the substance with the highest specific heat capacity will have the smallest temperature increase: by comparing the values in the table, we see that alluminium has the highest specific heat capacity (0.90 J/gC), therefore it will have the smallest temperature increase.
Answer:
<em>The first law states that</em> every planet describes an elliptical path about the sun as a single focus.
<em>The</em><em> </em><em>second</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The line joining the planet to the sun sweeps out equal areas in equal time intervals.
<em>The</em><em> </em><em>third</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The squares of the period of revolution is proportional to the cubes of the mean distance between the planet and the sun
Hello!
Answer and explanation:
There are three main sources of heat in the deep earth:
1) heat from when the planet formed and accreted, which has not yet been lost.
2)frictional heating, caused by denser core material sinking to the center of the planet.
3) heat from the decay of radioactive elements.
Have a good day
Answer:
5 no
Explanation:
actually the 4kg lying on table has no influence
it slides towards 4kg weight hung
as it has excess 2kg force
force=miu × m ×g
