Answer: solid

Explanation:In a solid, the atoms are closely packed and hence are close together. This results in a definite pattern of packing and a definite shape. Solids have a defined shape and volume as a result of this orderly arrangement of atoms very close to each other in the solid material.

Harman [31]

Answer:

$\boxed{\text{10 L}}$

Explanation:

We have two pressures, two temperatures, and one volume.

This looks like a question in which we can use the Combined Gas Law to calculate the volume.

$\dfrac{p_{1}V_{1}}{T_{1}} = \dfrac{p_{2}V_{2} }{T_{2}}$

Data:

$\begin{array}{rclrclrcl}p_{1}& =& \text{2 atm}\qquad & V_{1} &= & \text{10 L}\qquad & T_{2}& =& \text{400 K}\\p_{2}& =& \text{4 atm}\qquad & V_{2} &= & \text{?}\qquad & T_{2}& =& \text{800 K}\\\end{array}$

Calculation:

$\begin{array}{rcl}\dfrac{2 \times 10}{400}& =& \dfrac{4V_{2} }{800}\\\\0.050& = &0.0050V_{2}\\V_{2}& = &\mathbf{10 L}\end{array}\\\text{The final volume is }\boxed{\textbf{10 L}}$

Which of the following is NOT something that electromagnetic waves and mechanical waves have in common?

Svetlanka [38]

Answer:

D. In both, vibrations occur in a parallel direction to the direction of the wave.

Explanation:

It is not true that in both mechanical and electromagnetic waves, vibrations occur in parallel direction to the direction of the wave.

As with all waves, they are disturbances that transfers energy without moving the materials of the medium.

Electromagnetic waves have only one way of propagation which is a vibration in both parallel and longitudinal direction.
Mechanical waves can be propagated either in a parallel direction or longitudinal direction and not both.
