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:
Option A
Explanation:
From fundamental equation of motion
where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.
Since the initial velocity is zero
Making acceleration, a the subject of the formula then
Substituting 5 m/s for v and 2.5 m for s then
Answer:
The radius of the circular plate is 0.774 m
Explanation:
Given;
distance between the parallel plates, d = 1.53 cm = 0.0153 m
electric field energy density between plates, = 4.41 J/m³
Potential energy of the capacitor, = 0.127 J
Energy density is given as;
where;
V is volume
Volume is given as;
V = Ad
where;
A is area
A = V / d
A = (0.0288) / (0.0153)
A = 1.882 m²
Area of circular plate is given as;
A = πr²
where;
r is the radius of the circular plate
Therefore, the radius of the circular plate is 0.774 m
Answer:
ans: 6 m/s
Explanation:
spaceship 1 has mass= 150kg
initial momentum of spaceship 1 = 900 kg•m/s
we know,
momentum = mass × velocity
so,
velocity = momentum/mass
= 900 / 150
= 6 m/s
since we know it was initial momentum so, velocity is initial speed,
