This is the phase of matter with no fixed shape or volume.
LUCKY_DIMON [66]

Answer: Gas

Explanation:

Matter exists in three different phases, they are:

- Solid

the phase of matter with fixed shape, high density and non-moving particles that are held together by strong bonds. Example of solids are stone and chalk

- Liquid

the phase of matter with loosely held particles that are held together and take up the shape of the containing vessel. Examples of liquid are water, orange juice

- Gas

This is the phase of matter with no fixed shape or volume, rather its molecules travel rapidly and randomly within the containing vessel. Examples of gases are ammonia and oxygen

Thus, the phase of matter with no fixed shape or volume is known as gas

Which of the following statements is true about the variation of pressure in function of the depth? O Pressure decreases exponen
mrs_skeptik [129]

Answer:

The answer is: Pressure increases linearly with the depth

Explanation:

In this case, the definition of pressure is:

P = \frac{F}{A}

where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider \rho = m/V, then

P = \frac{mg}{A} = \frac{\rho Vg}{A}.

Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.

So

P = \frac{A\rho gh}{A}= \rho g h,

which means that pressure increases linearly with the depth in a factor of \rho g.

Which of the following four circuit diagrams best represents the experiment described in this problem?
Valentin [98]

We don't see any circuit diagrams.  

This worries us for a few seconds, until we realize that we don't know anything about the experiment described in the problem either, so we don't have to worry about it at all.
