The world record for the fastest train on Earth was set by abullet train from Tokyo to Osaka in Japan. Without passengers,it can travel at a speed of 300 km/hr. How many centimeters
per second can it travel?
cm/sec. *round to nearest whole number *

Answers

Answer:

8333

Explanation:

300km/hr = 300/60 = 5 km per min

5km/min = 5/60 = .08333333km per sec

km to cm = 100000, so

.083333 * 100000 = 8333

The train would travel at a speed of 8333.33 centimeters/second.

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.

As given in the problem the world record for the fastest train on Earth was set by a bullet train from Tokyo to Osaka in Japan. Without passengers, it can travel at a speed of 300 kilometers/hour,

1 kilometer = 1000 meters

1 meter = 100 centimeters

300 kilometers = 300×100000  centimeters

the speed of the fastest train = 300×100000  centimeters /3600 seconds

                                                = 8333.33 centimeters/second

Thus, the speed of the fastest train would be 8333.33 centimeters/second

Answers

Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.

Variation in the factors of climate leads to variable temperature around the world.

The rate of temperature change does not stay constant over time because of changes occur in the climatic factors. The climatic factors such as latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds can't remain constant which leads to variable temperature in different regions of the world.

The temperature will remain the same if all the world has same environmental conditions so we can conclude that variation in the factors of climate leads to variable temperature around the world.

explain at least two differences between justice system laws and scientific laws.

Answers

The adversarial system is rigid – the roles are proscribed – the prosecutor wants to convict, the defendant wants a decision of not guilty. They are not just allowed but expected to bias their presentation, trusting the truth to come out between the adversaries. Science certainly has its sides of partisanship and bias. But these sides are self-imposed and can be abandoned at any time. While a prosecutor should not lie or hide evidence, and should drop a case if they become convinced the defendant is innocent, they wake up in the morning with no choice about which side of the argument they will come down on. In the criminal justice system the advocates are rigidly fixed in their roles and the jurors are rigidly neutral (the process to find a random neutral jury took as long as the trial itself). In science, the advocates are the same people as the jurors. And as a result they have to be willing to be flexible and change their minds. A good scientist shouldn’t have a pre-determined rigid answer to a question.
Lack of investigation – we jurors were told over and over not to investigate the situation ourselves. We were to make our decision only on the basis of the evidence presented to us. I can tell you in the case I was on there were at least two whopping big questions hanging over the case that nearly every juror in the room identified as very important but not addressed by either lawyer. Either one of them (whether the defendant’s schedule allowed time to drink before being stopped in the car, whether a particular medical condition could affect breathalyzer tests) could have changed the outcome. We could have answered one of these with 10 minutes on google and the other with some very simple subpoena of records. But we couldn’t use any of this. Scientists obviously are the opposite – if they need more information, they are expected to go get it before making an opinion.
Reliance on personal testimony – although science and trials share a focus on evidence, trials recognize testimony of individual people under oath as a major form of evidence. They certainly acknowledge the possibility of lying and explicitly instruct jurors to decide what testimony they believe. My case was unusual in that there was so much video footage, but still a majority of the case came down to testimony by the police officers, and most cases even a few years ago would have had only testimony. Science on the other hand, doesn’t accept testimony. Or does it? What else is the methods and results section of a paper? I’m on the fence whether science is so different on this one.

Explanation:Flexibility and stretching: preventing sports injuries

  Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you  don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your  flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.  JUST STAY FIT

In what ways are plasmas similar to gases? What makes plasmas different than gases?

Answers

It takes a very special environment to keep plasmas going. They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the nucleus.

Answer:

Like gases, the particles in plasmas are constantly moving at high speeds, and do not have a definite shape or volume. Plasma is formed when the kinetic energy of the molecules in a gas gets very large and the temperature gets very high. This causes electrons to be released by the atom, creating ionized particles, which are positive ions and negative electrons.

Explanation:

Just answered on Apex

Metal is the material will heat up the most quickly if placed near a heat source. Option D is correct.

What is heat ?

The movement of energy from a hot to a cold item is characterized as heat. Heat energy flows from a hot material to a cold one.

This occurs because faster-vibrating molecules transmit their energy to slower-vibrating ones. Heat content is another name for vibrational energy.

It is hot or chilly depending on how much heat is there in the body. The body will be hotter as the heat content increases. The movement of energy from a hot to a cold item is characterized as heat.

The heat flow in the material is due to the free electrons. In the metal, no of free electron is highest. Metal is the material will heat up the most quickly if placed near a heat source.

approximate maximum height that the water balloon can reach? (Recall that g
= 9.8 m/s2)
O A. 7.0 m
B. 4.6 m
C. 9.3 m
D. 13.8 m

Answers

Answer:

A. 70 m OS the correct one

The approximate maximum height that the water balloon can reach is 13.8 m, The correct option is D.

What is the conservation of energy?

Conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed, only transformed or transferred from one form to another. In other words, the total amount of energy in a closed system remains constant over time. This principle is based on the idea that energy is a fundamental property of the universe, and it is a key concept in many areas of science, including physics, chemistry, and engineering. The law of conservation of energy is used to analyze and understand a wide range of physical phenomena, from the behavior of subatomic particles to the workings of the entire universe.

Here in the Question,

The maximum height that the water balloon can reach can be found using conservation of energy. The initial potential energy stored in the slingshot is transformed into kinetic energy of the water balloon as it is launched into the air, and then into potential energy at the maximum height.

The initial potential energy of the slingshot is given by:

PE = (1/2)kx^2

where k is the spring constant (60 N/m) and x is the distance pulled back (1.5 m)

PE = (1/2)(60 N/m)(1.5 m)^2

PE = 67.5 J

At the maximum height, all of the initial potential energy is converted into potential energy due to gravity:

PE = mgh

where m is the mass of the water balloon (0.5 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the maximum height.

h = PE/(mg)

h = 67.5 J/(0.5 kg)(9.8 m/s^2)

h ≈ 13.8 m

Therefore, the approximate maximum height that the water balloon can reach is 13.8 m, which is option D.

Explanation:

Given:

Δy = 0 m

v₀ = 20 m/s
