The image shows a pendulum in simple harmonic motion. the pendulum starts at a and swings to e.

which labels are correct? check all that apply.

e: net force is zero.
d: velocity is decreasing. acceleration is increasing.
a: velocity is zero.
c: acceleration is maximum.
b: velocity is decreasing. net force is decreasing.
e: velocity is maximum.
mark this and return save and exit next

D: Velocity is decreasing. Acceleration is increasing.

A: Velocity is zero.

The pendulum starts from rest at A, hence the velocity of pendulum at A is zero.

So velocity is zero at A

As the pendulum swings from A to E, it first gains speed from A to C and the speed decreases from C to E coming to a momentary stop at E.

Similarly, as the pendulum swings from A to E, the acceleration first decreases A to C (becoming zero at C) and the acceleration increases from C to E coming to a maximum at E.

So

D: Velocity is decreasing. Acceleration is increasing.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

the force on the thing and the distance the force moves the thing
