Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V = 
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' = 
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa
New pressure of gas = 400 KPa
Answer:
A wave transfers energy through a medium or empty space without transporting matter.
Explanation:
- A wave is a transmission of a disturbance from one point known as the source to another.
- Waves may transfer energy through a material medium or a vacuum without transporting matter.
- Waves that transfer energy from one point to another through a material medium are known as mechanical waves.
- Electromagnetic waves, on the other hand, are those that do not require a material medium for transmission, the transfer of energy is through a vacuum.
- Waves can also be either transverse or longitudinal waves based on the vibration of particles relative to the direction of wave motion.
Answer:
two north poles and two south poles
Explanation:
A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.
No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.
Answer:
The correct answer is the first option
