Answer:
The time taken is 
Explanation:
From the question we are told that
The mass of the ball is 
The time taken to make the first complete revolution is t= 3.60 s
The displacement of the first complete revolution is 
Generally the displacement for one complete revolution is mathematically represented as
Now given that the stone started from rest 
Now the displacement for two complete revolution is
Generally the displacement for two complete revolution is mathematically represented as
=> 
=> 
So
The time taken to complete the next oscillation is mathematically evaluated as
substituting values
When pushing a toy truck up an inclined plane, the force that makes the truck goes up is the force that the child uses to push the truck. (The force that pushes
Therefore the correct option is C.
Answer:
True
Explanation:
The image produced a convex mirror is always virtual irrespective of location. The size of the image is always smaller than the object. In a plane mirror the distance of the object and the distance of the image is same. But in a convex the image distance is always less than the object distance.
So, this statement is true.
