What is the volume of 27 g of aluminium?

Answers

Answer:10cm3

Explanation:Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. *

Answer:

Explanation:

as we know that

density=mass/volume

given mass of Al=27 g  

density of Al=2.70g/cm^3

volume =mass/density

volume=27/2.70

volume=10 cm³

so 27 g of Al has volume of 10 cm³

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.

Rubber

Answers

Answer:

Metal

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.

Hence, option D is correct.

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

Answers

Answer:

Speed greater than 4 m/s

Explanation:

Given that Ms. Kasper is in a panic. Her cat, Penny, is stuck in a tree and about to jump out. In order to save her cat, Ms. Kasper needs to run to the tree, 12 meters away. If it takes her cat, 3 seconds to fall, how fast would Ms. Kasper have to run to save her cat?

The distance = 12 m

Time = 3s

Speed = distance/time

Speed = 12/3

Speed = 4 m/s

Ms Kasper must run at speed more than 4m/s for her to save the cat.

A rock is thrown straight upward with an initial velocity of 20 m/s where the downward acceleration due to gravity is -10 m/s^2. How long is the ball in the air before it returns to the thrower's hand?

Answers

Answer:

4 seconds

Explanation:

Given:

Δy = 0 m

v₀ = 20 m/s

a = -10 m/s²

Find: t

Δy = v₀ t + ½ at²

0 m = (20 m/s) t + ½ (-10 m/s²) t²

0 = 20t − 5t²

0 = 5t (4 − t)

t = 4

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.

The snow fell in typical New York flurries, and the ground was still icy from last nights freeze. Careful not to slip, she climbed the steps and crossed the campus toward the science building."What am I doing?" she murmured. Sophies worst habit was talking to herself in public. "I have been warned.""You are just a high-school kid, Sophie," they warned. "What makes you think you are capable of solving this crucial environmental issue? Stop wasting your time." The professors would not give her laboratory time to complete research nor would they share their expertise with her.But, she could not stop.After a snorkeling trip she took with her aunt to the coral reefs, she felt that something had shifted inside her. The snorkeling guide made one fact very clear: these colonies of tiny organisms would not last. In fact, wed be lucky if they lasted five more years. She cared about the safety of these coral reefs more than she has cared about anything for a long, long time. She had to do something for the fragile, endangered habitat with its fish, mollusks, worms, crustaceans, and many more.She used her money to create a lab at her aunts house. She worked tirelessly--endlessly--sleeping only when she had to."Its what Mom and Dad would have done," she thought.Sophie's best friend, Sam, would hang out with her every day--eating pizza, fries, and whatever else he could get his hands on, keeping her company with his humor while she worked on her experiments. And now, she has a biological solution in her hands.She hesitated at the door to the labs. Nervously, she shifted her lab report from one hand to the other."I know that I have an innovative approach to solving the coral reef issue and I know I can help," she said to no one. The image of being ridiculed by these professors delayed her entry. She stood outside the door, wanting to run back--wanting to hide--glued to the icy spot."Hey, Sophie!" She turned at the unexpected sound of Sams voice."Ive beentrying to catch up with you," he panted, out of breath. "Lets go in andshow themwhat youve got."Sophie tilted her head, smiled at Sam, and opened the door.
