Chapter 5, Problem 5.32P

Interpretation Introduction

(a)

Interpretation:

Calculate the mass and weight of the helium in the balloon.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$

Where, the volume (V) occupied by ‘n’ moles of any gas has a pressure (P) at temperature (T) in Kelvin and ‘R’ = Gas constant

Archimedes’ Principle

According to Archimedes' principle the upward buoyant force experienced by a body immersed in a fluid is equal to the weight of the fluid displaced by that body.

Interpretation Introduction

(b)

Interpretation:

Calculate the force exerted on the balloon restraining cable.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$

Where, the volume (V) occupied by ‘n’ moles of any gas has a pressure (P) at temperature (T) in Kelvin and ‘R’ = Gas constant

Archimedes’ Principle

According to Archimedes' principle the upward buoyant force experienced by a body immersed in a fluid is equal to the weight of the fluid displaced by that body.

Interpretation Introduction

(c)

Interpretation:

The initial acceleration of the balloon should be estimated.
