Answer:
The temperature of air will increase by 
Explanation:
Given:
- no. of person in a theater,

- volume of air in the theater,

- rate of heat given off by each person,

- duration of movie,

- initial pressure in the theater,

- initial temperature in the theater,

- specific heat capacity of air at the given conditions,

<u>The total quantity of heat released by the total people in the theater during the movie:</u>



<u>Form the relation of heat capacity:</u>

∵



Change in temperature of air:

Answer:
Approximately
. (Assuming that this table is level, and that the gravitational field strength is
.
Explanation:
Convert the dimensions of this book to standard units:
.
.
Calculate the surface area of this book:
.
Pressure is the ratio between normal force and the area over which this force is applied.
.
Equivalently:
.
In this question,
.
It was found that
(assuming that the entire side of this book is in contact with the table.
Hence:
.
If that the table is level, this normal force would be equal to the weight of this book:
.
Assuming that the gravitational field strength is
. The mass of this book would be:
.
