True, buoyancy is the force a fluid exerts upon an object on its surface.
I think the correct answer would be <span>charged and insulated wire wrapped around a piece of iron. The charge in the wire would make magnetic fields through the aid of the magnetic properties of iron. Hope this helps. Have a nice day.</span>
Answer:
27°C or 300K
Explanation
We were told that the pressureof the system decreased by 10 times implies that P2= P1/10
Where P2=final pressure
P1= initial pressure
Wew were also told that the volume of the system increased by 5 times this implies that V2= 5×V1
Where T2= final temperature =-123C= 273+(-123C)=150K
T1= initial temperature
But from gas law
PV=nRT
As n and R are constant
P1V1/T1 = P2V2/T2
T1= P1V1T2/P2V2
T1=2×T2
T1=2×150
T1=300K
=300-273
=27°C
the initial temperature (°C) of a system is 27°C
<span>Density = mass / volume
3.32 kg = 3320 g
volume mass / density
3320 / 1.11 = 2990.99</span>
