Atransport plane takes off from a level landing field with two gliders in tow, one behind the other. the mass of each glider is 700 kg, and the total resistance (air drag plus friction with the runway) on each may be assumed constant and equal to 1900 n. the tension in the towrope between the transport plane and the first glider is not to exceed 12000 n. part a if a speed of 40 is required for takeoff, what minimum length of runway is needed? express your answer using two significant figures. part b what is the tension in the towrope between the two gliders while they are accelerating for the takeoff? express your answer using two significant figures. try to explain how you get to the answer.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
