Why can astronauts jump so high, and "hang" so
long, on the moon?

Answers

Answer 1

gravity is stronger on the earth, and gravity is what brings you back down

so, if there's less gravity, then there's more air time

Answer 2

Answer:

Low gravity

Explanation:

The moon has lower gravity than Earth, therefor when someone jumps, they will not return to the surface automatically.

What mass of benzene takes
up
325 mL if its density is
0.874 g/mL?

Answers

Answer:

The answer is 284.05 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 325 mL

density = 0.874 g/mL

We have

mass = 325 × 0.874

We have the final answer as

284.05 g

2. If a person in a wheelchair wanted to get to the second story of a two-story building, would it be easier to
take a short, steep ramp or a long, shallow ramp? Explain.

Answers

Answer:

The short steep ramp would be much harder because you will have to work more against gravity.

Explanation:

The long shallow ramp would be easier to take than the short, steep ramp because the person would have to use more force on the short, steep ramp to push the wheelchair against the force of gravity.

What is an inclined plane?

An inclined plane or a ramp can be defined as a flat supporting surface tilted at an angle, with one end higher than the other, utilized as an aid for raising or lowering a load.

The inclined plane can be defined as one of the six classical simple machines developed by Renaissance scientists. Inclined planes can be utilized to move heavy loads over vertical obstacles.

Moving a body up an inclined plane needs less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage, the factor by which the force is decreased, is equal to the ratio of the sloped surface's length to the height it spans.

The inclined plane provides the same amount of work to be done with a smaller force exerted over a greater distance. The angle of friction or the angle of repose can be defined as the maximum angle at which a load can rest motionless on an inclined plane because of the friction without sliding down.

Answers

Answer:

Physical change

Explanation:

There are two types of changes: physical change and chemical change. Physical change is defined as the change that changes the physical appearance of the substance and do not affcet the chemical composition of the substance whereas chemical change causes changes in the chemical composition of the susbstance.

The given example shows physical change because solid calcium undergoes sublimation. process in which a solid substance changes into gaseous phase directly without undergoing liquid phase.

A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​

Answers

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

[tex]n=\dfrac{PV}{RT}[/tex]

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

[tex]n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}[/tex]

[tex]n=0.009474\ moles[/tex]

Hence, The moles of gas is 0.009474 moles.

PLEASE HELP ILL MARK BRAINLIST TO WHOEVER GETS THIS CORRECT Read the passage.The OrnithopterMany people know Leonardo da Vinci today as an artist, and it is true that he was indeed a great painter and sculptor, but he was also an inventor and one of the first individuals in recorded history to draft detailed plans for a flying machine.In order to make a living, Leonardo often depended upon wealthy individuals who would commission work from him. That means they would hire him and pay him to create specific work they wanted. In 1482, when he was 30 years old, Leonardo heard of an opportunity to work for Ludovico Sforza, the Duke of Milan. The duke, however, did not want a painter; he wanted a military engineer to help him defend the city against its enemies. This was an excellent opportunity that would pay Leonardo well, but Leonardo was a peaceful man. He considered war to be a beastly madness. He preferred to make things of beauty.Leonardo made the decision that he could tolerate making weapons if the resources the duke could provide would also allow him to create things he loved. He sent a letter to the duke detailing his skills in designing and building weapons. I will assemble catapults, mangonels, trebuchets and other instruments of wonderful efficiencyI will make an infinite number of items for attack and defense, he wrote.Leonardos letter convinced the duke of his talents, and he got the job. He set about designing the weapons that the duke desired. But Leonardo was infinitely creative, always thinking of new things, new ideashe could not be limited to weapons alone. One idea that he had not mentioned in his application was the ornithopter. It was not a weapon of war, and it was not something that the duke had asked for, but Leonardo went ahead and designed it anyway.Leonardo was fascinated by the idea of flight. The word ornithopter comes from two words meaning bird and wings. And on first inspection, his plans resembled a birds wings attached to a human beings arms. He concluded that a human beings arms were neither strong enough nor light enough to stay in the air for long. So, his design included sets of foot pedals and levers that were operated with the hands. He created detailed plans and presented them to the duke, uncertain of how the duke would react to a design for which he didnt ask.As it turned out, the duke was very impressed with the ornithopter, but it wasnt Leonardos innovation that excited him. He immediately thought of the ways this machine could be used in war. If a spy could fly over the enemys camp, imagine what information he could gather! This was not what Leonardo had intended for his beautiful flying machine.But how Leonardo felt about war turned out not to matter in the end. His ornithopter was never builtalong with his designs for tanks, parachutes, diving suits, machine guns, and even robots that he created for the duke. The ideas of Leonardo da Vinci were centuries ahead of the technology needed to make them.What is a central idea of "The Ornithopter"?Select the two correct answers.A. Leonardo da Vinci's ideas about flight were ahead of their time.B. The duke's plan for the ornithopter conflicted with that of da Vinci's.C. Leonardo da Vinci was a creative genius.D.

So what do you do if you still want to ride with your friends?First, never ride your bike if it has a flat tire. Riding around on a flat tire is 2not only difficult but also dangerousfor both you and your bike. Riding a bike with a flat tire can cause you to fall and injure yourself and may damage your bikes wheel. 3Its less complicated and less expensive to fix a flat tire than it is to replace an entire wheel.Before you begin to fix the flat tire, you need to make sure that you have the proper materials. You will need 4a new inner tube a bike pump and two tire levers. Once you gather these items, you are ready to get started.The first step is to take the affected wheel off your bike and, if necessary, let out any remaining air. To remove the tire from the rim, insert a tire lever under the edge of the tire between the tire and the wheels rim. 5Then insert another lever a few inches away from the first, and push down on the end of each lever to lift the tire away from the rim. At this point, you can use your hands to pull the flat inner tube out from inside the tire.Now you are ready to put in the new tube. First, pump up the tube with a little bit of air, 6and it takes the basic shape of a tire and is easier to handle. Then, gently put the valve of the tube through the hole in the rim and insert the rest of the tube into the tire, being careful not to twist it. Some air could escape from the tube during this step, so you may need to pump a little more air back into the tube to help 7it kept its shape. With your hands, gently start tucking the edge of the tire back into the rim.Once you get most of the way around, you will need to use the tire levers again to assist you with the unyielding tire. Be sure not to pinch the new tube between the tire and the rim during this step because you can tear the tube. Once the tire pops back onto the rim, take your pump and fill the tire completely. After you get the wheel back on your bike, youll be ready to ride!What change, if any, is necessary to item 7?A) NO CHANGE B) it is keeping its shape. C) it keep its shape. D) it keeps its shape.
