Answer:
D is the answer wave behavior
At t=0, the particle was at its equilibrium position. The time period is 32 seconds, so in 8 seconds, it will reach the extreme location once, and hence, in 8 seconds, it will cover a distance equivalent to its amplitude.
Answer:
the net force would be 3N in the upward direction since the two forces acting on the left and right of the object cancel out.
