A 2.0 mL syringe has an inner diameter of 6.0 mm, a needle inner diameter of 0.25 mm, and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. Assume the liquid is an ideal fluid.a. What is the minimum force the nurse needs to apply to the syringe?b. The nurse empties the syringe in 2.0 s. What is the flow speed of the medicine through the needle?

The drawing shows an intravenous feeding. With the distance shown, nutrient solution (p = 1020 kg/m³) can just barely enter the blood in the vein. What is the gauge pressure of the venous blood? Express your answer in millimeters of mercury. Atmospheric pressure 0.610 m Number i Units

Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force (in N) must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 23.0 cm in diameter and the gauge pressure inside is 3.50 atm? Neglect the weight of the lid. N

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 44.4 N. If m1 = 18.7 kg, m2 = 23.0 kg, and m3 = 33.9 kg, calculate (a) the magnitude of the system's acceleration, (b)the tension T1, and (c) the tension T2.

The spring of the pressure gauge shown in the figure below has a force constant of 1 350 N/m, and the piston has a diameter of 1.40 cm. As the gauge is lowered into water in a lake, what change in depth causes the piston to move in by 0.700 cm? 4.635 X Your response differs from the correct answer by more than 10%. Double check your calculations. m Vacuum

Pressure cookers use water at very high pressures to cook food very quickly. They have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). a. How much force, in newtons, must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 27.5 cm in diameter and the gauge pressure inside is 0.95 atm? Neglect the weight of the lid.

A house weighs 12,000 pounds. a. Air normally has a density of 1.29 kg/m^3 but at 250 degrees air has a density of 0.9 kg/m^3. What volume of hot air balloon is needed to float this house off the ground? b. At standard temperature and pressure Helium has a density of 0.16 kg/m^3. How many 30 cm diameter helium balloons will it take to float the house?
