Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]
Its module is:
Its angle is:
Answer: The internal heat energy of the boat heat engine, metamorphoses into mechanical workdone that causes the boat to move.
Explanation: First law of thermodynamics tells us that energy cannot be created nor destroyed, it can only be transformed from one form to another.
The internal heat energy of the boat heat engine, metamorphoses into mechanical workdone that causes the boat to move.
According to the second law of thermodynamics which state that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while
