An aeroplane flies in a loop (a circular path in a vertical plane) of radius 200 m. the pilot's head always points toward the centre of the loop. the speed of the aeroplane is not constant; the aeroplane goes slowest at the top of the loop and fastest at the bottom. at the top of the loop, the pilot feels weightless. what is the speed of the aeroplane at this point?
at the bottom of the loop, the speed of the aeroplane is 280 km/h . what is the apparent weight of the pilot at this point? his true weight is 710 n .

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
