How long would it take an airplane to travel 1350m if it started from rest and accelerated at a constant 3.00 m/s^2?

Answers

The time taken for the airplane to travel 1350 m from rest is 30 s

Data obtained from the question

The following data were obtained from the question:

Initial velocity (u) = 0 m/sDistance (s) = 1350 mAcceleration (a) = 3 m/s² Time (t) = ?

How to determine the time

The time taken to travel the distance of 1350 m can be obtained as follow:

s = ut + ½at²

1350 = (0 × t) + (½ × 3 × t²)

1350 = 0 + 1.5t²

1350 = 1.5t²

Divide both sides by 1.5

t² = 1350 / 1.5

t² = 900

Take the square root of both sides

t = √900

t = 30 s

Thus, it will take 30 s for the plane to travel a distance of 1350 m

Is a rocket in the process of launching, Balanced or Unbalanced force?

Answers

The forces during rocket launching are unbalanced as, without unbalanced force, there can not be any motion.

Forces constantly balance and become out of balance during a rocket flight. On the launch pad, a rocket is balanced. Gravity tries to pull the rocket down, but the surface of the pad pushes it upward.

When the rocket's engines are lit, the thrust from them causes the forces to become out of balance, which causes the rocket to ascend. For a rocket to launch from a launch pad or for a spacecraft to change speed or direction, an unbalanced force must be applied.

Therefore, when the rocket is in the process of launching, the forces that act on the rocket are unbalanced.

When a moving body's direction changes, its velocity doesn't always go to zero. Only when the body's total displacement is zero does velocity become zero.

A change in the body's state of motion is reflected in either a change in the body's speed or its direction of motion. A force is an attempt to alter the status of an object, whether it is stationary or moving. The speed shift might indicate acceleration or slowdown (deceleration). Acceleration measures the change in speed as opposed to velocity, which measures speed in a vector (also in a vector).

Answers

The physicist traveling, according to his own testimony at -6.6 × 10⁷ m/s.

How fast was the physicist traveling, according to his own testimony?

Using the formula for doppler shift for light,

λ' = λ√[(1 + v/c)/(1 - v/c)] where

λ = wavelength of source, λ' = wavelength of observer, v = speed of source and c = speed of light

Given that the driver is moving away from the stop light, we take the driver as the source. Since, the Doppler shift made the red light of wavelength 650nm appear green to him, with a wavelength of 520nm. we have

λ' = wavelength of source = 650 nm, λ' = wavelength of observer = 520 nm

So, substituting the values of the variables into the equation, we have

λ' = λ√[(1 + v/c)/(1 - v/c)]

520 nm = 650 nm√[(1 + v/c)/(1 - v/c)]

520/650 = √[(1 + v/c)/(1 - v/c)]

0.8 = √[(1 + v/c)/(1 - v/c)]

Squaring both sides, we have

0.8² = (1 + v/c)/(1 - v/c)

0.64 = (1 + v/c)/(1 - v/c)

0.64(1 - v/c) = (1 + v/c)

0.64 - 0.64v/c = 1 + v/c

0.64 - 1 = v/c + 0.64v/c

-0.36 = 1.64v/c

-0.2195 = v/c

v = -0.22c

v = -0.22 × 3 × 10⁸ m/s

v = -0.66 × 10⁸ m/s

v = -6.6 × 10⁷ m/s

Why is the following situation impossible? A team of researchers discovers a new gas, which has a value of γ = C_P / C_V of 1.75.

Answers

A team of researchers discovers a new gas, which has a value of 1.75 which is impossible. Because the value of the heat capacity is 1.66.

What is the heat capacity ratio?

The heat capacity ratio sometimes referred to as the adiabatic index, the ratio of specific heat, or Laplace's coefficient in heat engineering and thermodynamic parameters, is the fraction of the heat capacity at constant pressure [tex]( \rm C_P)[/tex] to the heat capacity at constant volume [tex](\rm C_V)[/tex].

For the mono-atomic gases, the heat capacity ratio is maximum, then it decreases with bi-atomic gases, and it further decreases for tri-atomic gases.

A group of scientists finds a new gas with a heat capacity of 1.75 which is impossible. Due to the maximum heat capacity value is 1.66.

Nights and DragonsFrom the memoir of author Abigail Prynne1I sit at my desk listening to thunder growl outside my window. Flashes of light burst through the darkness, and wind races past my window. The thrilling combination of sight and sound conjures up visions of dragons roaring proudly, breathing fire, and soaring across the midnight sky. Dragons first fascinated me when I was a little girl. They have followed me ever since. The magnificent creatures appeared in storybooks I read in the library, paintings I saw in museums, movies I watched in the theater, and the dreams I had in my sleep. By the time I was thirteen, one question consumed me. I wanted to know if dragons ever existed, so I set out on a quest for facts.2As I started my research, I discovered many skeptics. Scientists presented evidence to show why dragons could notand did notexist. They explained that it would be impossible for dragons to fly because they would be too big. They laughed at the idea of dragons breathing fire. They pointed out that no other animal has ever done this. They said that if dragons had lived, someone would have found remains somewhere in the world. No bones about it, there were plenty of logical explanations. It would have been easy for me to accept that the only place dragons ever existed was in the imaginations of those who believed.3I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed.4With renewed hope that there was some truth to the legends, I looked for new research. I found that some experts disagreed with popular arguments against dragons. They suggested that a dragon could have four stomachs like a cow. If it created stomach gases like birds, it might create enough to lift itself off the ground. This would give it the ability to fly. If it forced out air when diving toward the earth, it might release gases which could ignite into flame. When the animal died, the stomachs would release strong acids that would dissolve its dead body over time. Biologists backed up these ideas with sketches and models based on known animals. Not everyone agreed with these ideas, but many of the things we accept about dinosaurs and other extinct species started the same way.5I doubt we will ever truly know whether dragons existed. There may always be two sides to the fiery debate. Some will say the stories come from active imaginations. Some will believe with all their hearts that the legendary creatures roamed our ancient world. I don't know for certain which side to believe, but the sound and fury of a night like this makes me smile. It rekindles my childhood dreams and keeps the exciting possibility alive.Which sentence from paragraph 4 makes an explicit statement without offering any implicit suggestions? your class nominates one student to attend student government association meetings on behalf of the class and report back on what was discusseda, direct democracyb, representative democracy Read the paragraph from the section "Shellfish."Lower pH values occur naturally on the West Coast during upwelling events, but recent observations indicate that CO2 originating from human activities is contributing to seasonal aragonite undersaturation. Scientists suspect that low pH may be a factor in the oysters' reproductive failure. More research is needed to disentangle potential acidification effects from other risk factors. Nonetheless, acidification is a potential factor in the current crisis to the multi-million-dollar oyster industry.
