An airplane in a wide sweeping ""outside"" loop can create zero gees inside the aircraft cabin. what must be the radius of curvature of the flight path for an aircraft moving at 150 m/s to create a condition of ""weightlessness"" inside the aircraft?

2.295 km

Explanation:

Given

velocity of aircraft

As the airplane moves around the earth in a circular therefore plane must experience a centripetal force towards the center of the earth which will be provided by gravitational force.

Gravitational Pull

Centripetal Force

Where m=mass of Airplane

r=radius of curvature

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

overcharge is the right answer system
