A balloon filled with helium plus air at atmospheric pressure is designed to support a mass of 116 kg (payload + empty balloon). Air density is 1.29 kg/m^3, helium plus air density in the balloon is 0.296 kg/m^3, and helium density is 0.179 kg/m^3. Ignoring the volume of the payload, find the volume of the balloon. Answer in units of m^3.

In the theory of plate tectonics, various segments of Earths crust, called plates, move toward and away from each other. In one instance, the plate that consists of the Indian subcontinent drifted from southeastern Africe to its current position in asia, traveling at a speed of 15cm/y. This plate collided with Asia, forming the Himalayan mountain range in the process. Most of this formation occurred during the last 1.00 x 10^7 years, during which time the indian subcontinents motion has slowed to about 5 cm/y. What has been the acceleration in units of cm/y^2, of the indian subcontinent during this time period.
