Answer:

Explanation:
Torque,  is given by
 is given by
 where F is force and r is perpendicular distance
 where F is force and r is perpendicular distance
 where
 where  is the angle of inclination
 is the angle of inclination
Torque,  can also be found by
 can also be found by
 where I is moment of inertia and a is angular acceleration
 where I is moment of inertia and a is angular acceleration
Therefore, Fr=Ia and F=mg where m is mass and g is acceleration due to gravity
Making a the subject,  and already I is given as
 and already I is given as  
 hence
 hence  
 
 
Taking g as 9.81,  is given as 37 and L is 1.2
 is given as 37 and L is 1.2
 
 
 
        
             
        
        
        
One situation in which force is created is when an object is moving and a force is created to stop that movement. Second situation is when an object is moving circularly and a force is created to move it towards the middle of the circle. The third situation is when a force is created that goes in the same direction as an object that is in movement.
        
             
        
        
        
Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste.
Explanation:
 That is why the cell needs to be small
 
        
             
        
        
        
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
