Answer:
Explanation:
Given
No of logs 
diameter of log 
Length of log 
42 % of log volume(V) is above water when no one is on raft
so 58 % of log volume(V) is submerged in the water
Weight of 14 log

Buoyancy force on 14 logs
as system is in equilibrium so



Specific gravity of log 
The answer is C. 3 meters per second (m/s)
Hopes this helps and if you can can you give me brainiest
It’s c the same thing that is the same
Answer:
Explanation:
In case of rotational motion, every particle is rotated with a same angular velocity .
The relation between linear velocity and angular velocity is
V = r w
Where v is linear velocity, r is the radius of circular path and w be the angular velocity.
Here w is same for all the particles but every particle has different radius of circular path I which they are rotating, so linear velocity is differnet for all.
