Answer:
B. equals zero
Explanation:
Given data
one complete cycle = heat flow
solution
we have given that when heat engine complete 1 cycle change in energy = net heat flow
that is always equal to zero
from first law of thermodynamics that
ΔU = Q + W
we know ΔU is the change internal energy in system and Q is net heat transfer in system and W is net work done in system
therefore change of internal energy during one cycle
ΔU = Ufinal - Uinitial
ΔU = Uinitial - Uinitial = 0
Answer:
0.176m from the flagpole, westward.
Explanation:
Let the Eastward be the positive direction. So initially runner A is at position -6km, running with velocity of 9km/h while runner B is at position 5km running at a velocity of -8km/h. We can conduct the following equation for their distances over the same time t
When A an B meets, they are at the same position and at the same time. So
So where they meet is 0.176m from the flagpole, westward.
