10. The diagram shows a mercury manometer connected to a gas container. The density of mercury is 13 600 kg/m3 The gravitational field strength g is 10 N/kg. What is
the pressure difference between the gas in the container and the atmosphere?
A 27 200 Pa
B. 40 800 Pa
C 54 400 Pa
D. 81 600Pa

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

Anybody wanna ? (picture included? )

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
