The physical quantity that is neglected when practicing tailgating is :
Distance TailgatingTailgating is the act of driving or following a vehicle very closely and this can be very dangerous as well, during this act the distance between the vehicles is been neglected by the driver.
Distance is the difference in position of an object with time in respect to another object. ( i.e It is a scalar quantity ).
Hence we can conclude that the physical quantity that is neglected when practicing tailgating is Distance.

if you are riding on a train that speed past another train moving in a same direction on an adjacent track ti appears that the other train is moving backward why?
Answer:
If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards

Humans selectively breed cows that produce more meat or milk. This selection is not necessarily helpful
to increase their survival rate. They are just selecting a desirable characteristic. How can growing one
variety affect cows population over many generations?
There will be less genetic diversity in the population.
The cows will produce less milk or less meat over generations.
The cows will be able to survive for a longer time.
There will be more genetic diversity in the population.
Answer:
The cows will produce less milk or less meat over generations.
If thermal energy is added to a liquid, what is the most likely thing that will happen to the substance?
Explanation:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
A car that weighs 40,000 N is driving down a hill at a constant velocity. If the car’s momentum is 80,000 kg∙m/s, how fast is the car moving?
The velocity of the car is equal to 20 m/s.
Given the following data:
Weight of car = 40,000 Newton.Car’s momentum = 80,000 kg∙m/s.Scientific data:
Acceleration due to gravity = 10 [tex]m/s^2[/tex].To determine the velocity of the car:
How to determine the car's velocity.First of all, we would calculate the mass of the car by using this formula:
[tex]Weight = mg\\\\40000=m \times 10\\\\m=\frac{40000}{10}[/tex]
Mass, m = 4,000 kg.
For the velocity:
Mathematically, momentum is giving by this formula;
[tex]Momentum = mass \times velocity[/tex]
Making velocity the subject of formula, we have:
[tex]Velocity = \frac{Momentum}{Mass}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Velocity = \frac{80000}{4000}[/tex]
Velocity = 20 m/s.

Which phenomenon do solar panels rely on to produce electricity from sunlight?
Answer:
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

Box is kicked (given an initial speed), causing it to slide along a level floor. There is friction acting between the box and floor surfaces. What is true about this motion
Answer:
I would assume that the box slows down due to the frictional force between the floor and the box. In addition, the frictional force points opposite of the boxes motion. As we know, the box was given an initial speed, therefore, having an applied force. Hence, we can conclude that the frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.
Hope that helps!
