Early test flights for the space shuttle used a "glider" (mass of 980 kg including pilot). After a horizontal launch at 400km/h from a height of 3300m , the glider eventually landed at a speed of 210 km/h. A) What would its landing speed have been in the absence of air resistance?

B) What was the average force of air resistance exerted on it if it came in at a constant glide of 12 degrees to the earth?

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

C) the periods  of day and night would be fixed all year for anyone at the  equator
