What would a plot of p versus 1/v look like for a fixed quantity of gas at a fixed temperature?

Romashka-Z-Leto [24]

Answer:

Straight Line

Explanation:

For an ideal gas,

PV = nRT

For a fixed quantity ( constant number of moles) of a gas at fixed temperature

Right side of the equation will be constant

Thus,

PV = C

So, P = $\frac{C}{V}$ .

Thus P is directly related to $\frac{1}{V}$

That's why plot between P and $\frac{1}{V}$ will be an straight line.

A piece of iron block moves across a rough horizontal surface before coming to rest. The mass of the block is 1.3 kg, and its in

KengaRu [80]

Answer:

0.0126°C

Explanation:

Kinetic energy sustain by the block,K.E = 1/2× mass×velocity^2

K.E = 1/2 ×1.3×(4^2)

=1/2 × 1.3× 16 = 1.3 ×8 = 10.4J

The internal energy is 71% of kinetic energy is;

U= 71/100 × 10.4 = 7.38J

But U = m × C × ∆T

Where U is internal energy

m is the mass of iron

C is the heat capacity of iron

∆T is the temperature change

By make ∆T the subject of the formula we have

∆T=U/ m×C

=7.38/ 1.3×452= 0.0126°C

Newton's laws of motion work well for ordinary situations on earth. However, these laws of motion do not work for all cases. Und

Alexandra [31]

Answer:

C: for objects at extremely fast speeds.

Explanation:

Newton's second law does not hold for extremely fast speeds, because then relativistic effects come into play, where Einstein's theory of special relativity is a more correct description.

The reason why F=ma does not hold for fast speeds is that, as an object moves faster and faster, the proportional relationship between force and acceleration does not hold. As an object moves faster and faster, it becomes harder and harder (requires more force) to accelerate it. because it gains mass as a virtue of its velocity (what's called relativistic mass).

For relativistic speeds, the correct modification of Newtons second law is:

$F=\frac{dp}{dt}$

where $p$ is the relativistic momentum:

$p=\frac{mv}{\sqrt{1-\frac{v^2}{c^3} } }$
