On sources it says it would just be the super giant star
normal force because it is perpendicular to the surface
Answer: 15m/s
Explanation: <u>Average</u> <u>Velocity</u> is vector describing the total displacement of an object and the time taken to change its position. It is represented as:

At t₁ = 1.0s, displacement x₁ is:

x(1) = 28
At t₂ = 4.0s:

x(4) = 73
Then, average speed is

v = 15
The average velocity of a car between t₁ = 1s and t₂ = 4s is 15m/s

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:
