Answer:
<h3>
The coefficient of kinetic friction between the puck and the ice is
0.12</h3>
Explanation:
Given :
Initial speed 
Displacement
m
From the kinematics equation,

Where
final velocity, in our example it is zero (
),
acceleration.


From the formula of friction,

Minus sign represent friction is oppose the motion
Where
( normal reaction force )
( ∵
)
So coefficient of friction,


Therefore, the coefficient of kinetic friction between the puck and the ice is
0.12 .
Explanation:
Earwax helps to protect your ears from infection so if you like chewing gum, this helps in removing the wax. But this might not happen at your young age. So if you grow and still likes chewing gum it will remove the wax completely thereby leading to loss on hearing
In a distance vs time graph what does the slope represents the Velocity
Answer:
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
Explanation:
The atmosphere composes of 78% nitrogen which occupies the largest percentage followed by oxygen which takes up 21%, Argon takes up 1% then other components such as water vapor occupy between 0-7% and ozone takes 0.0-0.01. Moreover, 0.01-0.1 is occupied by carbon dioxide. Therefore, the answers for 1-5 are as follows.
1. Nitrogen
2. Oxygen
3. Carbon dioxide
4. Water vapor
5. Ozone
The answer should be 5 it’s easy
