Answer:
Honestly i think the answer is B
Explanation:
The answer is A it’s more safer that way
Answer:
2.00 N
Explanation:
Weight is mass times gravity:
W = mg
Mass is density times volume:
m = ρV
Volume of a cylinder is:
V = πr²h
Finding the volume:
V = π (2.00 cm)² (6.00 cm)
V = 75.4 cm³
The density of aluminum is 2.7 g/cm³. Finding the mass:
m = (2.7 g/cm³) (75.4 cm³)
m = 204 g
Finding the weight:
W = (0.204 kg) (9.8 m/s²)
W = 2.00 N
The aluminum cylinder weighs 2.00 N.
Answer:
so simple it is a square formula
Answer: 3,893,845.918 Ping-Pong balls
Explanation:
The volume of an average room is:
(1)
(2)
Now let’s transform this 
to units of 
, knowing 
:
(3)
On the other hand, we have Ping-Pong balls with a radius 
, and their volume is given by:
(4)
(5)
(6)
Now, the number 
of Ping-Pong balls that can be packed into the room is:
(7)
(8)
This is the number of Ping-Pong balls that can be packed into an average size room
