1) A U-tube, in which both ends are open to the atmosphere, is partially filled with water. Oil which does not mix with water is poured into one side of the tube until it stands a distance d=12.3 mm above the water level on the other
side which has meanwhile risen a distancea=67.5 mm from its original level Find the density of the oil
2) The mercury column in a barometer has a measured height h of 740.35 mm. the temperature is-5.0 C
which temperature the density of mercury is 1.3608 104 kg/m3. the free-fall acceleration at the site of the
barometer is 9.7835 m/s2. What is the atmospheric pressure?
