There is only one pressure this situation would be a "constant pressure" process
Answer:
The mass of the rule is 56.41 g
Explanation:
Given;
mass of the object suspended at zero mark, m₁ = 200 g
pivot of the uniform meter rule = 22 cm
Total length of meter rule = 100 cm
0 22cm 100cm
-------------------------Δ------------------------------------
↓ ↓
200g m₂
Apply principle of moment
(200 g)(22 cm - 0) = m₂(100 cm - 22 cm)
(200 g)(22 cm) = m₂(78 cm)
m₂ = (200 g)(22 cm) / (78 cm)
m₂ = 56.41 g
Therefore, the mass of the rule is 56.41 g
Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.
Q=mc x delta T
Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.
Solve for change in temp=. Q/mc
Specific heat and mass are not inversely proportional to heat energy input.
Putting into real world scenario of using water to heat a building.
Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF
Acetone specific heat is .51
So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.
<span>This is because the sun never goes beyond the Tropical of Capricorn and the Tropical of Cancer </span><span><span>whcih are approximately 23.5 degrees S and N respectively</span>. The 66 degrees latitude N and S is the Arctic and Antarctic regions. Because if you add 23.5 and 66 = 90 degrees (approximately), you realize that the sun rays are unable to reach these regions, during winters, because light cannot bend over 90 degrees (light moves in straight lines and only diffracts). </span>
Answer:
14J
20000J
200J
Explanation:
formula :W=FS
W:work done
F:force (N)
S:displacement moved in direction of force (m)
1) 20N×0.7m
=14J
2) 400N×50m
= 20000J
3) 10N×20m
=200J
