A bullet is fired through a board 10.0 cm thick in such a way that the bullet’s line of motion is perpendicular to the face of the board. If the initial speed of the bullet is 400 m/s and it emerges from the other side of the board with a speed of 300 m/s, find the acceleration of the bullet as it passes through the board and find the total time the bullet is in contact with the board.
This question is a Physics question. Thank you :)
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.

According to the information in the table above, which of the following statements is true if both countries have the same number of workers?
According to the information in the table above, the statement which is true if both countries have the same number of workers is that: Country A has an absolute advantage in manufactured goods but a comparative advantage in service goods.
What is a comparative advantage?A comparative advantage can be defined as the ability of a business firm or country to produce goods and services at a lower opportunity cost than their rivals (competitors) or trade partners.
What is an absolute advantage?An absolute advantage can be defined as a measure of the ability of an individual or a business firm (manufacturer) to perform a specific economic activity such as the production of goods and services, more efficiently than another individual or business firm.
In this scenario, we can reasonably infer and logically deduce that the statement which is true if both countries have the same number of workers is that Country A would have an absolute advantage in the production of manufactured goods but a comparative advantage in the production of service goods because it can produce 100 units and 300 units respectively in comparison with Country B.

Which phrase describes neap tides?
occur four times a day
produce extra-low tidal ranges
caused only by the pull of the moon
occur at the same time as spring tides
The neap tides produce extra-low tidal ranges. The correct option is B.
What are neap tides?A neap tide is a period of moderate tides seven days after a spring tide, when the sun and moon are at right angles to each other. A spring tide is a historical term that has nothing to do with the spring season.
Spring tides have higher highs and lower lows, while neap tides have lower highs and higher lows. As a result, the range (difference in water level between high and low tide) in a spring tide is much greater than in a low tide.
Thus, the correct option is B.

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)

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.

Here is why I am so passionate about criminal justice, even though there is much more to come.
There are numerous career routes in this area of study, ranging from C.I.A. agents to forensic psychologists. I find a lot of the responsibilities performed by those in these professions appealing. 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 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.
