Newton's first law of ketchup is if the bottle of ketchup is smacked upward, the contents (the ketchup) will tend to remain in place, and it will be closer to the opening in the bottle.
Further explanation
If we are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle a upward smack which force the bottle rapidly upward.
Newton first law said that every object tries to continue in its state of rest or uniform motion unless an external force acted upon it (In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force). Newton first law describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
Inertia explained by Sir Isaac Newton in his first law of motion (Newton law of motion). The law states that an object at rest stays at rest and an object continues its state of motion until an external force acts on it. The examples are one's body movement to the side when a car makes a sharp turn

The ketchup inside the bottle is take out by shaking the bottle up and down. This process of bringing out the ketchup from the bottle make use of Newton’s Law of Inertia or the Newton’s first law.
Further Explanation:
The Newton’s first law of motion or the Newton’s law of Inertia states that a body continues to be in its state of rest or motion until and unless an external force is applied on the body that forces the body to change its state.
This law states that there needs to be a force in order to change the state of a body whether it is in motion or it is at rest.
The ketchup inside the bottle always settles down towards the bottom of the bottle. Now when it is required to take out the ketchup from the bottle, we hold the bottle upside down and shake it to bring the ketchup out of the bottle.
As the bottle is turned and shaken, the ketchup bottle suddenly comes into state of motion whereas the ketchup inside the bottle still remains in its state of rest. As the bottle goes up, the ketchup slides down to the neck of the bottle as it wants to remain in its initial position.
In this manner, when the bottle is shaken several times, the ketchup comes out of the bottle slowly. This process of taking out the ketchup from the bottle is due to the Newton’s law of Inertia.
The Newton’s first law or Law of Inertia has its several other applications in day to day life.
• The passenger tend to fall forward in a moving bus when the driver slams the brake suddenly. It happens because due to brakes, the bus comes to rest suddenly but the passenger’s body still remains in its state of motion and therefore, it tends to fall forward.
• The dust particles come out from a mattress when it is beaten up by a stick. The beating up the mattress sets up the mattress into motion but the dust particles remain in their state of rest and therefore, they fall out of the mattress.
Thus, the technique of bringing out the ketchup from the bottle by shaking it is an application of the Newton’s first law or the Newton’s Law of Inertia.

Answer: Hello mate!
The velocity of the pony is constant in magnitude, so you may think that the pony is not acelerating, but you need to notice that the track has an ocal shape.
This means that the direction of the velocity is changing all the times, this mean that there is an "acceleration" changing the direction of the velocity, this is called centripetal acceleration, then the pony is accelerating around the track.
The right answer is C.
The answer is c i took the test

Final answer:
Non-examples of speed include acceleration, direction, time, distance, inertia, momentum, and force. These concepts relate to other aspects of motion, not the rate of motion, which speed measures.
Explanation:
Non-examples of speed would be any factors or measures that don't directly pertain to the measurement of an object's change in position or distance over time. These could include factors such as acceleration, which involves the rate of change of speed; direction, which becomes a concern when we deal with velocity, not speed; and elements like time or distance separately.
For instance, projections about gravitational pull on vehicles while in motion would be non-examples because they relate more to the forces affecting the motion, rather than the motion itself. Similarly, an object's inertia or momentum, and the force applied to an object also do not exemplify speed, as they pertain to mass and force, not the rate of motion.
It's also essential to distinguish between instantaneous speed, average speed (total distance divided by elapsed time), and constant speed (speed that doesn't change over time). These are all variations of speed, but one concept isn't interchangeable with the others based on the context of the motion being described.

1. The volume will increase.
2. The change in the volume is 73 mL
1. Determination of the nature of the new volume.
From the question given above, the following data were obtained:
- Initial volume (V₁) = 200 mL
- Initial temperature (T₁) = 0 °C = 0 + 273 = 273 K
- New temperature (T₂) = 100 °C = 100 + 273 = 373 K
- New volume (V₂) =?
Using the Charles' law equation, the new volume of the cylinder can be obtained as follow:
V₁ / T₁ = V₂ / T₂
200 / 273 = V₂ / 373
Cross multiply
273 × V₂ = 200 × 373
273 × V₂ = 74600
Divide both side by 273
V₂ = 74600 / 273
V₂ ≈ 273 mL
From the above calculation, we can see that the new volume increased.
2. Determination of the change in the volume.
The change in the volume can be obtained as illustrated below:
- Initial volume (V₁) = 200 mL
- New volume (V₂) = 273 mL
- Change in volume (ΔV) =?
ΔV = V₂ – V₁
ΔV = 273 – 200
ΔV = 73 mL
