<span>Good Morning!
When the light passes through a lens - whether of increase or withdrawal - it tends to be refracted, that is, to suffer a deviation in its trajectory. Depending on the type of lens, it may be that some of the light is reflected too, but this is not the common parameter.
Correct letter is therefore c).
Hugs!Hope this helps. Let me know if you need additional help!</span>
Energy = mass * SHC * temp change
Temp change = energy/SHC * mass
42kJ - 42000J (convert kJ to J as energy is counted as J/kg)
Temp change = 42000/4200*10
= 1C
So it goes up by 1C thus the final temperature would be 26C
Or a more logical way to think of it would be that if it takes 4200J to heat up 1kg of water by 1C (SHC is 4200J/kgC) it would take ten times the amount of energy to heat up 10kg of water by 1C hence it takes 42000J.
It’s distance for my answer but tell me if anyone tells u this answer thanks
B.Radiation, Because the heat is Radiating of of the burner. xD
The answer
<span>According to Newton’s first law, if no force acts on an object, it will just continue moving in a straight line with a constant speed or at rest
that means that the sum of all acting forces equals 0
</span>so the car must
exert a force between the car and the road to drive at a constant speed on a straight and level road because the both forces must be balances for making it to move <span><span>with a constant speed in a straight line.</span> </span>
