Answer:
Explanation:
= Initial pressure = 
= Initial volume
= Final volume = 
Temperature is the same in the initial and final state
From the ideal gas law we have
The final pressure of the system is .
Answer:
Technician b is correct.
Explanation:
Crimping cable allows a firm connection in mechanical terms and allows a low resistance path for the signal or the current flow, solder although it is better in terms of electrical conduction, can be impractical if the cable is subjected to excessive movement.
A crimped cable with excessive movement can also be easily broken at the ends, where it joins the part of the cable that is crimped, for this reason, a cable that is in excessive motion is recomended to be spliced by joining cable with cable
.
In order to decide which metod is better for splicing cables its necessary to evaluate each situation separatly.
It's Decrease or cease to exist, but I'm leaning more towards decrease.
It could an acid that dissociates (dissolves) 10%
Answer:
Explanation:
Given:
mass of lead chunk, 
height of the fall, 
- Assuming the collision to be perfectly inelastic the whole kinetic energy of the chunk is lost after the collision.
- Here when the chunk is at the given height it has a potential energy which on falling transforms into kinetic energy of the chunk.
So, increase in the internal energy of the system after the collision is :
