Answer:
C. Equal amounts of gases occupy the same volume at constant temperature and pressure.
Explanation:
As we know by ideal gas law that
now here we have
so as per Avagadro law if the temperature and pressure of the gas is constant then volume of the gas is directly proportional to the number of moles of the gas.
so correct answer will be given as
C. Equal amounts of gases occupy the same volume at constant temperature and pressure.
Explanation:
Mass of the crate, m = 68 kg
We need to find the resulting acceleration if :
(a) Force, P = 0
P = m a
⇒ a = 0
(b) P = 181 N
(c) P = 352 N
Hence, this is the required solution.
Answer:
The velocity of the block is 231650.8 ft/s
Explanation:
Knowing
W = 10 lb
v0 = u = 4 ft/s
F = 8 lb
ms = 0.2
Applying the newton second law
ΣFy = 0
N - W = 0 --> N = W = 10 lb
ΣFx = m
F - ms N = ma
- 0.2(10) =
a =
Using Kinematics
a = dv/dt
=
=
v - 4 = 3.22
when t = 30
v = 231650.8 ft/s
