Explanation:
volume=3x4x6=72cm³
density=mass/volume
so:
184.32/72=<u>2</u><u>.</u><u>5</u><u>6</u><u>g</u><u>/</u><u>cm³</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>block</u>
All you have to do is multiply that by the mass or volume.
1. turn off lights in classrooms when not in use.
2. turn off all computers when not in use.
3.use a small amount of water when washing your hands.
4. Don't charge your cell phones during class.
5. open windows instead of using air conditioner

Explanation:
Answer:
The total angular momentum of the system is
.
Explanation:
Given that,
Angular speed = 0.841 rad/s
Mass of platform = 72.1 kg
Speed = 1.17 m/s
Mass of poodle = 20.3 kg
Mass of mutt = 18.5 kg
Distance =3/4 of the platform's radius from the center
Mass of disk = 92.5 kg
radius = 1.87 m
Angular momentum is the product of moment of inertia and angular speed.
We need to calculate the angular momentum of person





We need to calculate the angular momentum of platform

Put the value into the formula


We need to calculate the angular momentum of poodle

Put the value into the formula


We need to calculate the angular momentum of mutt



We need to calculate the total angular momentum



Hence, The total angular momentum of the system is
.
