$2)$ Which experiment had more random error? Justify your answer using a calculation.

$3)$ Using the theoretical value for the bulk modulus that you obtained in the question above,

which method for the measurement of the bulk modulus is more accurate? Show

calculations and interpret your result.

$4)$ For the static and dynamic method of calculating the bulk modulus, give an example of

either random or systematic error.

$5)$ According to the specifications of our barometer, it hasand accuracy $($uncertinaty$)$ of$4$ mbar. If we propagate this onto our value of Btheowhat do you get for Btheo Note : $1$ bar$=105$Pa

$6)$The Bulk Modulus of Helium is $27$ MPa $(27$x$106$Pa$)$ Using the Bulk Modulus value

you obtained for air, which is more compressible: Helium or air? How would exchanging

the air in the room for Helium affect the motion of the ball?
