Answer:Science can solve societal problems, and it can affect societal decisions.
Explanation:
Sound energy cannot travel through a vacuum.
Explanation:
Waves are periodic disturbance of the space, which travel carrying energy but not matter.
There are two types of waves:
- Mechanical waves: mechanical waves propagate through the vibrations of the particles in a medium. Examples of mechanical waves are sound waves.
- Electromagnetic waves: these waves consist of periodic oscillations of electric and magnetic fields, perpendicular to each other. These waves do not need a medium to propagate, so they can also travel in a vacuum.
In this problem, we are analyzing sound energy, which is the energy carried by sound waves. Sound waves are mechanical waves, so they need a medium to propagate: therefore, they cannot travel through a vacuum, since there is no medium.
So, sound energy cannot travel through a vacuum.

Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.
The input voltage is 120 V and the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
<h3>
Input voltage </h3>
The input voltage of the transformer is the voltage of the primary coil and it is calculated as follows;
Ns/Np = Es/Ep
where;
- Ns is the number of turn in the secondary coil
- Np is the number of turn in the primary coil
- Es is the secondary voltage
- Ep is the primary voltage
2X/X = 240/Ep
2 = 240/Ep
Ep = 240/2
Ep = 120 V
Thus, the transformer is a step up transformer due to increase in the voltage induced in the secondary coil.
