Answer:
r = 0.5 m
Explanation:
First we find the angular speed of the ball by using its period:
ω = θ/t
For the time period:
ω = angular speed = ?
θ = angular displacement = 2π rad
t = time period = 0.5 s
Therefore,
ω = 2π rad/0.5 s
ω = 12.56 rad/s
Now, for the radius:
v = rω
r = v/ω
where,
v = linear speed = 6.29 m/s
r = radius = ?
r = (6.29 m/s)/(12.56 rad/s)
<u>r = 0.5 m</u>
Answer:
Positively charged nuclei are packed in an organized pattern, and the negatively charged valence electrons flow freely.
Explanation:
You are in an early universe.
In the study of the evolution of the universe, it has been determined before Plank time (before the big bang and right after it), the early universe had the following characteristics:
- There was only one single force acting over all that existed.
- The early universe was very hot and dense because all matter had contracted before the big bang.
- Space and time were wrapped.
These characteristics match the ones described, based on this, we can conclude you are in an early universe.
