about 50 years ago, the san diego zoo, in california, had the largest gorilla on earth: its mass was about 30.10x10^2 suppose a gorilla with this mass hangs from two vines, each of which makes an angle of 30.0° with the vertical. draw a free-body diagram showing the various forces, and find the magnitude of the force of tension in each vine. what would happen to the tensions of the upper ends of the vines were farther apart

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

Could someone me find the answer to this problem.
