Because atoms is something that pops or has bubbles in it
To solve this problem it is necessary to use the conservation equations of both kinetic, rotational and potential energy.
By definition we know that

Where,
KE =Kinetic Energy
KR = Rotational Kinetic Energy
PE = Potential Energy
In this way

Where,
m = mass
v= Velocity
I = Moment of Inertia
Angular velocity
g = Gravity
h = Height
We know as well that
for velocity (v) and Radius (r)
Therefore replacing we have

Therefore the height must be 0.3915 for the yo-yo fall has a linear speed of 0.75m/s
Answer:
9800 Pa
Explanation:
Data: pressure-?
Force- mass ×acceleration
= 50× 9.8m/s^2
=490N
Area= 500cm^2=0.05m^2
pressure= force/ area
p=F/A
P= (490N)/( 0.05m^2)
=9800 Pa
