almost everything artafitial would have been made because of science. However nothing natural would exist because of science. All science does is look around and see what's up.
 
        
                    
             
        
        
        
Answer:
Angular speed, 
Explanation:
It is given that,     
The top of the leaning bell tower at Pisa, Italy, moved toward the south at an average rate of, v = 1.2 mm/yr

Velocity, 
Height of the tower, h = 55 m
The height of the tower is equivalent to the radius. Let  is the angular speed of the tower’s top about its base. The relation between the angular speed and the angular speed is given by :
 is the angular speed of the tower’s top about its base. The relation between the angular speed and the angular speed is given by :




So, the average angular speed of the tower’s top about its base is  . Hence, this is the required solution.
. Hence, this is the required solution.
 
        
             
        
        
        
Answer:
3. they can travel through solids
4. they move rock at right angles to the direction of wave travel
Explanation:
- S waves are called transverse waves they have the ability to move past the solids. They cannot move through the liquids, these waves are perpendicular to the direction of travel.  
- They are also called longitudinal waves, the ad is second to record on the seismograph as they slowly pass through the rocks. They have a speed of 3.4 to 7.2 km as per the boundary.
 
        
             
        
        
        
Answer:
- solution, 
- Given
- load =400N
- ld=0.2m
- ed=0.6m
- effort =150N
Explanation:
efficiency =output work/input work ×100%
l×ld/e×ed×100%
400×0.2/150×0.6×100%
80/90×100%
