(a) If a 1.0-N force is applied to the plunger, what is the gauge pressure in the syringe’s chamber? (b) If a small obstruction is present ...A solid ball has a weight of 3.0 N. When it is sub-merged in water, it has an apparent weight of 2.7 N. What is the density of the ball? A spherical navigation buoy is tethered to the lake floor by a vertical cable (Fig. 9.40). The outside diameter of the buoy is 1.00 m. The interior of the buoy consists of an aluminum shell 1.0 cm thick, and the rest is ...In a dramatic lecture demonstration, a physics professor blows hard across the top of a copper penny that is at rest on a level desk. By doing this at the right speed, he can get the penny to accelerate vertically, into the ...
