Given the following data:
Initial velocity = 400 m/s
Final velocity = 300 m/s
Distance = 10.0 cm to m = 10/100 = 0.1 m.
How to calculate the acceleration of an object?Mathematically, the acceleration of this bullet can be calculated by using this formula:
a = (V - U)/t
Where:
V represents the final velocity.U represents the initial velocity.t represents the time measured in seconds.a represents the acceleration.However, we would have to use the third equation of motion to calculate the acceleration of this bullet because we do not know the time taken yet.
Mathematically, the third equation of motion is given by:
V² = -U² + 2aS
300² = -400² + 2(a)(0.1)
0.2a = 160000 + 90000
0.2a = 250000
a = 250000/0.2
Acceleration, a = 350,000
Acceleration, a = 1.25 × 10⁶ m/s².
For the time, we have:
t = (V - U)/a
t = (400 - 300)/1.25 × 10⁶
Time, t = 8.0 × 10⁻⁵ secs.

why is it possible to show a cause-and-effect relationship between two variables using a experiment and not an observational study
The reason why is it possible to show a cause-and-effect relationship between two variables using a experiment and not an observational study is Because observational studies are known to be unable to randomized, as they are also unable to control for all of the other inevitable things that can occur.
Why can't observational studies show cause and effect?Note that this happens due to the fact that observational studies are said to have no capabilities to randomized, and as such, they are unable to control all the inevitable.
Note that they are often shown to be unmeasurable, and they may be the factors that can be causing the results. Thus, this makes the cause and effect in observational studies to be speculative.

Various aspects of life depend on your career and interests. My career interests fall under the Criminal Justice System category. This field focuses on retributive justice. One may have to investigate people or places, gather information, or to work at the scene of a crime. While there is much more to follow, here is why I have a passion for criminal justice.
This field of work has many paths to follow stretching from C.I.A. agents to forensic Psychologists. Many of the duties carried out by those in these positions appeal to me. I have met and have known people involved in local accidents. I spend vast amounts of time researching and studying motives and deciphering complex cases. I often watch documentaries and take notes on recurring patterns and compare them to rare situations in crimes. When studying online or through documentaries is not enough, I rely on books or my cousin who became a forensic scientist to work on the case of the DC Killer. But this is more inclusive than murder. My interest also goes as far as robbery, substance abuse, and cyber security.
The reason I am so infatuated began when I was young. I realized everyone had their share of hardships, large or small. My will to ensure their well-being and safety only grew, I had to know why those occasions happened and how to prevent such. Growing up it was easy to empathize with those around me. I liked being able to relate and place myself in their shoes to find the best solution.

I have known and interacted with individuals involved in nearby accidents. I invest a lot of effort in learning about motives, analyzing situations, and conducting research.
I frequently watch documentaries, make notes about recurring themes, and contrast them with unusual circumstances in cases. When watching documentaries or learning online is not sufficient, I turn to books or my cousin, a forensic scientist who is working on the case of the DC Killer. But compared to murder, this is more inclusive. My interest extends to topics like cyber security, and others.
I was young when I first developed the obsession I have today. I came to see that everyone faced challenges, no matter how big or small. My desire to protect them and make sure they were safe only rose; I needed to understand why those incidents occurred and how to avoid them in the future. It was simple for me to relate to individuals around me as I was growing up. In order to find the greatest solution, I appreciated being able to empathize to them and put myself in their situation.

One can say that, for similar shape, one can write:
[tex]\frac{10}{15} =\frac{8}{x}[/tex]
[tex]10x=8*15\\x=\frac{120}{10}[/tex]

C. none of the above
D. a cubic meter of snow
E. a cubic meter of air

A physical object which would experience the greatest gravitational acceleration is: A. a cubic meter of lead.
What is a gravitational force?A gravitational force is also referred to as gravity and it can be defined as a universal force of attraction which acts between two (2) physical objects, especially by pulling them together.
What is a gravitational acceleration?A gravitational acceleration can be defined as the rate of change of the velocity of an object in free fall with respect to time, especially due to effect of a gravitational force. Also, gravitational acceleration is usually measured in meter per seconds square (m/s²).
Generally speaking, gravitational acceleration is highly dependent on the weight of a physical object. This ultimately implies that, the greater the weight of a physical object, the higher would be the gravitational acceleration it experiences.
In this context, we can reasonably infer and logically deduce that a physical object which would experience the greatest gravitational acceleration is a cubic meter of lead because it has the least weight in comparison to the other objects.

per second, downriver, in a river flowing at 3
meters per second, how fast is it going at 10
seconds
Based on the calculations, the final velocity of this object is equal to 43 meters per second.
Given the following data:
Acceleration = 4 meters per second per second.
Initial velocity = 3 meters per second.
Time = 10 seconds.
What is an acceleration?An acceleration can be defined as the rate of change of the velocity of an object with respect to time. Also, acceleration is usually measured in meter per seconds square.
How to calculate the acceleration of an object?Mathematically, the acceleration of this object can be calculated by using this formula:
a = (V - U)/t
Where:
V represents the final velocity.U represents the initial velocity.t represents the time measured in seconds.a represents the acceleration.Making V the subject of formula, we have:
V = U + at
Substituting the given parameters into the formula, we have;
V = 3 + 4(10)
V = 3 + 40
