Elaborate on the reason(s) that matter is said to move even as in a solid state.

1 answer:

3 0

1) The correct answer is
C) The particles are not able to move out of their positions relative to one another, but do have small vibrational movements.
In solids, in fact, particles are bound together so they cannot move freely. However, they can move around their fixed position with small vibrational movements, whose intensity depends on the temperature of the substance (the higher the temperature, the more intense the vibrations). For this reason, we say that matter moves also in solid state.

2) The correct answer is
A) increase the concentration of both solutions
In fact, when we increase the concentration of both solutions, we increase the number of particles that react in both solutions; as a result, the speed of the reaction will increase.

3) The correct answer is
C) gas → liquid → solid
In gases, in fact, particles are basically free to move, so the intermolecular forces of attraction are almost negligible. In liquids, particles are still able to move, however the intermolecular forces of attraction are stronger than in gases. Finally, in solids, particles are bound together, so they are not free to move and the intermolecular forces of attraction are very strong.

babunello [35]

Answer:

5010 m

Explanation:

The vertical position of the teacher at time t can be found by using the equation:

$y(t) = h + ut+ \frac{1}{2}gt^2$

where

h is the initial height

$u = -20 m/s$ is the initial velocity (negative since it's downward)

$g=-9.8 m/s^2$ is the acceleration of gravity

t is the time

The teacher reaches the ground when y = 0, so the equation becomes

$h=-ut-\frac{1}{2}gt^2$

Substituting t = 30 s, we find the initial height:

$h=-(-20)(30)-\frac{1}{2}(-9.8)(30)^2=5010 m$

How should Delana figure out how much power is needed to do 462 joules of work in 9.61 seconds?

Lostsunrise [7]

Answer: 48.08 watts

Explanation:

power needed = ?

Work done = 462 joules

Time taken = 9.61 seconds

Recall that power is the rate of energy expended or workdone per unit time. i.e Power = Workdone / Time

Power = 462 joules / 9.61 seconds

Power = 48.08 watts

Thus, 48.08 watts of power is needed to the work.

KonstantinChe [14]

I think the answer is D.
If we use the process of elimination, the wooden bat would not be able to fit in a jewelry box, it would not be in a laptop, assuming the filing cabinet is small and filled with files, the bat would not be hidden there, and the suspects automobile would be in the garage, which I don’t think counts as the house exactly.

What is not an example of Absorption? (Physics)

amm1812

When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption. ... In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray, for example).
