Your friend wants to know how to calculate the number of balloons she would need to float.

What would you need to know from her, and what instructions would you give in return?

(Be very specific! This is a risky experiment.) Pls Help me!

Final answer:

To calculate the number of balloons your friend would need to float, you need to consider the buoyant force exerted on the balloon. The buoyant force is equal to the weight of the fluid displaced by the balloon. Here are the steps to calculate the buoyant force.

Step-by-step explanation:

To calculate the number of balloons your friend would need to float, you need to consider the buoyant force exerted on the balloon.

The buoyant force is equal to the weight of the fluid displaced by the balloon. Here are the steps to calculate the buoyant force:

Determine the density of the fluid in which the balloon will float. For example, the density of air at sea level is approximately 1.225 kg/m³.

Calculate the volume of the balloon. For example, if your friend has a 2.00-L helium balloon, convert it to cubic meters (1 L = 0.001 m³).

Calculate the weight of the fluid displaced by the balloon. Multiply the density of the fluid by the volume of the balloon.

The buoyant force is equal to the weight of the fluid displaced by the balloon.

Keep in mind that this is a risky experiment, and safety precautions should be taken into consideration.
