A meteorologist has released a weather balloon to collect data. If the
meteorologist wants the balloon to hover above the Earth's surface, what
two forces need to be changed. Select the best TWO answers that fit the
question. (Hint: This is for two different scenarios.)
Buoyancy
Force -28N
Drag Force-6N
Gravitational Force-16N
The gravitational force needs to be increased by 6 Newtons.
The buoyancy force needs to be decreased by 6N
The buoyancy force needs to be increased by 6N
The drag force needs to be twice the buoyancy force
The drag force needs to be decreased by 2 Newtons.
