The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.
 
        
             
        
        
        
A wave is basically propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.
        
             
        
        
        
Answer:
21 miles
Explanation:
3 miles an hour for 7 hours 
Its simply 7m*3m/hr=21 miles
 
        
             
        
        
        
Answer:
Explanation:
Suppose v is the initial velocity and  is the angle of inclination
 is the angle of inclination
distance traveled in vertical direction in t=1 s
When gravity is present

where 



here initial velocity is v\sin \theta [/tex] so 


In absence of gravity
