Answer:
<em>The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile</em>
Explanation:
<u>Kinetic Energy
</u>
Is the capacity of a body to do work due to its speed and is computed by

We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:


So its kinetic energy is


The mass of the fly is

To have the same kinetic as the automobile:

Solving for 



The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile
Kinetic because u are moving around a lot!
Answer:
a. -8 cm
Explanation:
= distance of the object = 4 cm
= distance of the image = ?
= focal length of the converging lens = 8 cm
using the lens equation


= - 8 cm
Answer:
b. 9.5°C
Explanation:
= Mass of ice = 50 g
= Initial temperature of water and Aluminum = 30°C
= Latent heat of fusion = 
= Mass of water = 200 g
= Specific heat of water = 4186 J/kg⋅°C
= Mass of Aluminum = 80 g
= Specific heat of Aluminum = 900 J/kg⋅°C
The equation of the system's heat exchange is given by

The final equilibrium temperature is 9.50022°C
