An undersea research chamber is spherical with an external diameter of 4.60m . The mass of the chamber, when occupied, is 51100kg . It is anchored to the sea bottom by a cable.
What is the buoyant force on the chamber?
What is the tension in the cable?
Sketch a free-body diagram of the plank. How far can a painter of mass 70.0 kg walk on the overhanging part of the plank before it tips.
Consider the Earth and a cloud layer 900 m above the planet to be the plates of a parallel-plate capacitor. (a) If the cloud layer has an area of 1.0 km2 = 1000000 m2, what is the capacitance?
