A 60-kg pilot flies ajet in a half vertical loop of 1200-mradius so that the speed of the aircraftdecreases at a constant rate. The aircrafthas a speed of 560 km/h at A, andthe pilotexperiences weightlessness at point C (i. e., the normalforce fromthe seat bottom is zero). Find:(a)thedeceleration of the aircraft;(b) the force exerted on the pilotby the seatat point B; (c) direction of theforcewith the horizontal axis.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
