Answer:
Two possibities: Increase in pressure or decrease in temperature.
Explanation:
There are two possibilities under the assumption that mass of the gas is conserved and, consquently, the amount of moles is also conserved, a reduction in the volume of the gas leads to an increase in pressure (Boyle's Law) and a decrease in temperature (Gay-Lussac's Law)
Answer:
21.2m/s
Explanation
Given data
P=6.36 x 10⁴kg·m/s.
M=3000kg
From the momentum expression
P=mv
v=p/m
Substitute
v=63600/3000
v=21.2m/s
Hence the Velocity is 21.2m/s
The given question is incomplete. The complete question is as follows.
If gas in a cylinder is maintained at a constant temperature T, the pressure P is related to the volume V by a formula of the form
P = 
, in which a, b, n, and R are constants. Find 
.
Explanation:
We will use the quotient rule for each of the two terms on the right side as follows.
P = 
= 
= 
= 
Thus, we can conclude that the value of .
A wire that has electrical current successively over it makes a
magnetic field. Actually, the simplest electromagnet is a single
wire that is twisted up and has an electric current consecutively through it.
The magnetic field produced by the coil of wire is like a normal
bar magnet. Only definite materials, for instance iron, nickel, cobalt,
and gadolinium, display strong magnetic properties.
These materials are called ferromagnetic. Ferromagnetic
materials will react powerfully to magnets and can also be magnetized
themselves. Often an electromagnet is enclosed around a core
of ferromagnetic material, for example steel, which improves the magnetic field
produced by the coil.
