Answer: f=20 (i think)
Explanation:
all I did was divide 300 and 15.
300/15= 20
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
The material that makes up the medium such as air or water and the temperature.
Answer:
Transverse wave
Explanation:
The wave is moving forwards from the hand to the point of attachment
