Answer:
B
Explanation:
Because this oscillations occur when the restoring force is directly proportional to displacement, given as 
F=-kx
Where k= force constant
X= displacement
 
        
             
        
        
        
Answer:
Total distance = 700 m
Displacement = 500 m
Explanation:
Notice that Jed travelled a total of 3 x 100 m = 300 m in the North direction, and 300 m + 100 m = 400 m in the East direction. Therefore the total distance he travelled is:  300 + 400 = 700 m.
But the actual displacement is given by the Pythagorean theorem as the hypotenuse of a right angle triangle of legs 300 m and 400 m:
displacement =
