In this case, there are two forces that acts on the atmospheric science balloon. It is the force due to gravity or the weight and the buoyant force. A system at equilibrium should have the forces acting upon it equal. Therefore, the buoyant force would be equal to 2000N.
Answer:
I can't see it good on my phone sorry can't help you
Answer:
Venus is only 95% the size of Earth, and 81% of its mass. With the smaller size and mass, the force of gravity pulling you on the surface is lower. To get your weight on Venus, just multiply your current weight by 0.9. That's why 100 pounds becomes 90 pounds
