An astronomer writes down the following for an object in the night sky: azimuth 364˚ and altitude 93˚, what is wrong with the values?

Answers

I think 25 degrees . I am definitely going to be wrong probably though

If your azimuth is larger than 180 degrees, multiplying it by 180 degrees to find your rear azimuth will result in an azimuth that is greater than 360 degrees.

What azimuth 364˚, altitude 93˚, what is wrong with  values?

A circle has 360 degrees, thus if your azimuth is higher than 180 degrees, multiplying it by 180 degrees to find your back azimuth will result in an azimuth higher than 360 degrees.

Because many ancient calendars had 360 days, it may be because the stars appeared to rotate around the north star at a rate of around 1 degree every day that azimuth is measured using a 0-360° interval. Azimuth is utilized outside of astronomy in disciplines like navigation and geology.

Therefore, Whereas an object at 90 degrees height is directly overhead, one at 0 degrees altitude is just above the horizon.

What would happen to the digestion process if enzymes were not present

Answers

Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.

Explanation:

I hope this helps

Enzymes play a critical role in digestion by breaking down large food molecules into smaller molecules that can be absorbed by the body. If enzymes were not present in the digestive process, the body would not be able to break down food effectively, leading to a number of negative consequences.
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

\(2.613\:\cdot10^5\) Joules ; 5. Adding the same amount of heat to two different objects will produce the same increase in temperature ; 2. Same speed in both ; 2. A

Explanation:

Diagram 1 ( Liquid Nitrogen ) : So as you can see, we want our units in Joules here, and can therefore multiply the mass of gaseous nitrogen and the latent heat of liquid nitrogen, to cancel the units kg, and receive our solution - in terms of Joules. Let's do it.

q ( energy removed ) = mass of nitrogen \(*\) latent heat of liquid nitrogen,

q = 1.3 kg \(*\) 2.01 \(*\) 10⁵ J / kg = \(1.3\:\cdot \:2.01\:\cdot \:\:10^5\) = \(10^5\cdot \:2.613\) = \(100000\cdot \:2.613\) = \(261300\) Joules = \(261.3\) kiloJoules = 2.613 \(*\) 10⁵Joules is the energy that must be removed

Diagram 2 : The same amount of heat does not necessarily mean the same increase in temperature for two different objects. The increase in temperature depends on the specific heat capacity of the substance. Therefore your solution is 5 ) Adding the same amount of heat to two different objects will produce the same increase in temperature.

Diagram 3 : The temperatures in both glasses are the same, and hence the molecules have the same average speed. Therefore your solution is 2 ) Same speed in both.

Diagram 4 : Glass A has more water molecules, and hence has more thermal energy. Your solution is 2 ) A.

A skydiver dives from an airplane. Air resistance is measured each second following the skydiver’s jump. Which statement BEST identifies the skydiver’s speed at each second?
PLS HELP QUICK

A skydiver dives from an airplane. Air resistance is measured each second following the skydivers jump.

Answers

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

The average woodpecker smashes its beak against a hard surface more than 10,000 times a day. Any human who jolted their head like this would likely end up with a concussion. This traumatic brain injury is caused by a blow to the skull. So why doesn’t the constant hammering turn woodpeckers’ brains into mush? For years, it was assumed that woodpeckers had some kind of cushioning in their heads to protect their brains during pecking. Many scientists suggested that spongy bone in the birds’ skulls absorbed and lessened the shock of each impact (see Myth Buster: Hard Headed). This idea was repeated in scientific articles, textbooks, and informative plaques at zoos. Even though the concept “is often presented like a clear-cut fact, there haven’t been any real tests to prove it,” says Sam Van Wassenbergh. He’s a biologist who studies biomechanics, or how living things move, at the University of Antwerp in Belgium.SHOCK ABSORBER: Van Wassenbergh uses a spring-loaded hammer to show why a shock-absorbing skull would make a woodpecker less efficient at pecking. When you think about it, says Van Wassenbergh, the shock-absorbing skull idea doesn’t make much sense. Woodpecker drills into the wood in search of insects to eat. When the bird’s head accelerates forward, the movement generates kinetic energy. This energy of motion is transferred to the tree when the bird slams its beak against the trunk. If a woodpecker’s skull had to cushion, it would absorb some of this energy and decrease the force of the peck. Why would a bird that survives by pecking evolve to do it less effectively? Van Wassenbergh and his team decided to see what was really going on. First, the researchers recorded videos of woodpeckers’ heads in motion. To capture this rapid movement, the scientists needed special high-speed cameras. Each peck lasts only a fraction of a second! Van Wassenbergh’s team recorded videos of six woodpeckers from three species and analyzed the footage. The researchers used a computer to track three points on each bird’s head: one on the skull and two on the beak. The scientists hypothesized that if the birds’ skulls had shock absorbers, the footage would show a “squishing” of the space between the skull and beak—like when a spring compresses. But that didn’t happen. Instead, the birds’ heads moved as one stiff unit, like a hammer. Next, the team wanted to demonstrate why this adaptation would be helpful to the birds. Using computer models, the scientists simulated woodpecker skulls with and without shock absorbers. Then the researchers compared the force of the pecks. “The pecking performance was greatly reduced in the skull with a shock absorber,” says Maja Mielke, a biologist who worked on the study. With shock absorbers, says Mielke, “the poor birds would need to pound even harder to reach the same results.” For a woodpecker, having a shock-absorbing skull would simply be a waste of energy. Science World originally published this diagram in our May 10, 2021, issue. It was based on scientists’ beliefs about woodpecker anatomy at the time. Here it is again—updated based on new research. MYTH: The skull is made of spongy bone that cushions and protects the brain from impactBUSTED! The skull is hard enough to protect the bird from injury, but it doesn’t cushion The eyes have a special membrane that protects them from flying splinters and wood dust.MYTH: Neck muscles are strong and stiff enough to absorb the shock of each peck BUSTED! Stiff neck muscles do not absorb shock—in fact, they help increase the force of each peck.MYTH: The tongue wraps completely around the outside of the skull, providing an additional level of cushioning, and can extend to probe for food inside holes made by the birdBUSTED! The tongue does not provide any observable cushioning. The beak is connected to the skull with thick bone that prevents jolts and vibrations. NEW RESEARCH SHOWS: The woodpecker’s brain is small, which helps prevent concussions that might occur in a larger animal. If woodpeckers’ skulls don’t absorb shock, then why doesn’t constant pecking damage the birds’ brains? To answer this question, the researchers calculated how harmful the blows from pecking actually are. It turns out the hits aren’t that dangerous because the birds’ brains are so small. “Small masses can tolerate stronger impact forces without being damaged,” says Mielke.

Answer:

 The topic of the story is about how woodpeckers can peck without causing damage to their brains.

"The average woodpecker smashes its beak against a hard surface more than 10,000 times a day."

"This traumatic brain injury is caused by a blow to the skull."

"So why doesn’t the constant hammering turn woodpeckers’ brains into mush?"

The conclusion of the story is that woodpeckers don't get brain damage from pecking because their brains are small, which allows them to handle the force of the pecks.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
