Answer:
Given that
P = RT/V + a/V²
We know that
H= U + PV
For T= Constant (ΔU=0)
ΔH= ΔU +Δ( PV)
ΔH= Δ( PV)
P = RT/V + a/V²
P V= RT + a/V
dH/dV = d(RT + a/V)/dV
dH/dV = - a/V²
So the expression of dH/dV
b)
In isothermal process
(ΔU=0)
Now by putting the all values
ΔH = 17.06 L.atm
Answer:
70 + 50 = 120 km/hr
Explanation:
The driver of either car would see the other car approaching or departing at 120 kph
The muscular system is responsible for controlling the skeletal muscles and the muscles of the internal organs, including the heart, stomach and intestines. It connects with the nervous system and receives input from efferent neurons, allowing it to respond to external or internal stimuli.
Answer:
5.1m
Explanation:
Use the fourth key equation of accelerated motion
vf^2=vi^2+2aΔd
we know vf is = 0 because that is when the ball reaches it's peak (not going up anymore)
0=vi^2+2aΔd
and we can rearrange for Δd, which is what you need
-vi^2=2aΔd
Δd = -vi^2/2a
Now we can plug in the values
Δd = -vi^2/2a
Δd = -(10m/s)^2/2(-9.8)
Δd = -100/-18.6
Δd = 5.10m
My teacher said 36m when I asked her
