Adiabatic process is that process in which heat of a closed system will remain conserved or we can say that system can not exchange its thermal energy from its surrounding
So here from 1st law of thermodynamics we can say
since we know that
so we will have
so we have
so here correct answers are
<em>A. -ΔU = W </em>
<em>B. Heat is constant. </em>
I would think that you would have to do 42/2=21Hz, but I'm not sure...
Answer:
The expression for the magnitude of the accelerations is
Explanation:
According the Newton´s second law:
Clearing T for second equation:
T = ma + mg
Replacing in the first equation:
Mg - ma - mg = Ma
Ma + ma = Mg - mg
a(M + m) = g(M - m)
Answer:
Height of the rocket be one minute after liftoff is 40.1382 km.
Explanation:
v = velocity of rocket at time t
g = Acceleration due to gravity =
= Constant velocity relative to the rocket = 2,900m/s.
m = Initial mass of the rocket at liftoff = 29000 kg
r = Rate at which fuel is consumed = 170 kg/s
Velocity of the rocket after 1 minute of the liftoff =v
t = 1 minute = 60 seconds'
Substituting all the given values in in the given equation:
Height of the rocket = h
Height of the rocket be one minute after liftoff is 40.1382 km.
A decrease in production of goods could cause the economy to move from point a to point b.
<h3>What cause shifts in economy?</h3>
Shifts in the production are due to many factors that change the output of an economy such as advances in technology, changes in resources, more education or training and changes in the labor force.
So we can conclude that a decrease in production of goods could cause the economy to move from good to poor.
