at isothermal condition we know that when temperature is constant we will have

here we will have


Now gas is compressed and its final volume will become

now from above formula we have

now we have


so final pressure will be 285 kPa
Answer:

Explanation:
Suppose the tension in the ribbon is T.
The upwards component of the tension = Tcos13
The horizontal component of the tension = Tsin13
The weight of the medal = mg
In a vertical direction, mg is balanced by Tcos13, so mg=Tcos13, so T = mg/cos13. The horizontal component of T is the force causing m to accelerate.

Substituting T= mg/cos13 gives:

cancels and you have
