a) An object in equilibrium has a net force of zero.
- An object is said to be in equilibrium if all the forces acting on the object are balanced, so that the net force (=resultant of the forces) acting on the object is zero.

b) Static equilibrium describes an object at rest having equal and balanced forces acting upon it.
- An object is said to be in static equilibrium if it is at rest and all the forces acting on the object are balanced, so that the net force (=resultant of the forces) acting on the object is zero. In this case, the object will remain at rest, according to Newton's second law:
$\sum F = ma$
where the first term is the resultant of the forces acting on the object, m is its mass and a its acceleration. Since the resultant of the forces is zero, the acceleration is zero as well, and the object will remain at rest.

c) Dynamic equilibrium describes an object in motion having equal and balanced forces acting upon it.
- An object is said to be in dynamic equilibrium if it is in motion and all the forces acting on the object are balanced, so that the net force (=resultant of the forces) acting on the object is zero. In this case, the object will remain in motion with constant velocity, according to Newton's second law:
$\sum F = ma$
where the first term is the resultant of the forces acting on the object, m is its mass and a its acceleration. Since the resultant of the forces is zero, the acceleration is zero as well, and the object will not change its velocity.

No because a circle or pie graph usually shows percentages you'd need a line graph

Answer from: Quest

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
