Question

Physics

A spherical mylar balloon filled with Hydrogengas, with density 0.0899 kg/m3 andhaving radius 7 meters is immersed in a gas havingdensity X1=1.205 for the first 10km and X2=2.489 for the second 10km (with the upper atmosphere density smaller than thelower atmosphere density). Determine how long it takes the balloonto reach the top of the second layer. To do this, you will have to:a) find the net force on the balloon (assume the mylar is massless)in the first layer, then assuming constant acceleration, determinethe time to get to the bottom of the second layer, then b) repeatthe exercise, but now calculating the buoyancy using the secondlayer of atmospheric gas.
