I think it's the third one.

Why there must be an unbalanced force acting if an object is moving in a circle at constant speed?
If an unbalanced force was not acting upon it, it wouldn't be moving in a circle.An object with no unbalanced force will either not be moving, or be moving in a straight line due to Isaac Newtons 1st law of motion.
What is the number of newtons is the gravitational force minus the number of newtons for the drag in water?
That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.
What are 5 examples of unbalanced forces?
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
How can you increase the velocity of thre ore?
We can use Newtons 2nd law to figure this out. The formula is Force (Resultant) = Mass x Acceleration. The ores mass is constant. If you use a greater force, working out the formula, the velocity increases.
What forces work on a skydiver?
(standard air pressure and gravity)>(Constant) Force down (newtons) = mass * acceleration due to gravity>Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons>Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)>Terminal velocity (when forces balance) 687.4 = v 2 * 0.16Terminal velocity = square root (687.4 / 0.16)= 65.546 metres per second ( 147 mph) terminal velocity
Does newtons second law state that if an unbalanced force acts on an object it will move at constant velocity?
It can accelerate or decelerate, depending on the direction of force

What is a force that can cause an object to change its speed and direction?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
What happends if forces are unbalanced?
Movment. Ex.> force of 10 newtons-><-force of 5 newtons movement of 5 newtons->
Do newtons make stuff move faster?
A newton is a unit of force, and a force (if unbalanced) causes an acceleration. Acceleration involves any change of velocity - not just making things faster.
Is it true that an object in motion at a constant velocity will change its motion only if a central force acts on it?
yes it is one of newtons laws of motion
What are the two parts of newtons first law of inertia?
Newton's first law states that a body at rest will remain at rest and a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an unbalanced force. So the two parts involve a body at rest and a body in motion.
What does newtons first law of motion state about objects at rest and objects in motion?
An object in motion will not change its motion unless acted on by an external force. This applies to zero motion also.
What is the number of newtons is the gravitational force minus the number of newtons for the drag in water?
That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.
What does Newtons 1st law of motion state about objects on which forces are balanced?
Newton's first law says "Every body remains in a state of constant velocity unless acted upon by an external unbalanced force." This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant velocity.Newton's first law for moving objects with balanced force is that the object "behaves" like it has no force acting on it. Because the object has balanced force, the object has a net force of zero, and according to Newton's first law, an object that is in motion will not change its velocity unless an unbalanced force acts upon it. The object is therefore in uniform motion (aka moving at constant velocity).

Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
