What is the ideal banking angle (in degrees) for a gentle turn of 1.90 km radius on a highway with a 110 km/h speed limit (about 68 mi/h), assuming everyone travels at the limit

What are chlorofluorocarbons and what impact do they have on the atmosphere?

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.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?
