68) The Pitot tube is commonly used to measure the air speed of an aircraft. Air flows into a small opening at the end of a tube that is closed at the other end, bringing the air to rest and allowing the measurement of the pressure difference between air at rest inside the tube and air moving rapidly just outside the tube. If the high-altitude air density is 0.364 kg/m3, and the pressure difference between inside and outside the tube is 9460 Pa, what is the airplanes speed relative to the air?

2. What is the force of gravity between two 1000 kg cars separated by a distance of 20 m on a highway?Fg=r2Gm1m1Where G is the gravitational constant and r is the distance between the two objectsNow we can start plugging in the valuesG = 6.67 x 10^-11m1 = 1000 kgm2 = 1000 kgr = 20 mPlugging these into the equation yields us:Fg = 1.67 x 10^-7 N3. Using the force, calculated in # 2 above, and the weight of the car, calculate: Force (from #2) divided by the weight of car

A 4.80-kg block is at rest on a horizontal floor. If you push horizontally on the 4.80-kg block with a force of 12.0 N, it just starts to move.A 7.00-kg block is stacked on top of the 4.80-kg block. What is the magnitude F of the force, acting horizontally on the 4.80-kg block as before, that is required to make the two blocks start to move together?
