Explain why air is not a good conductor of heat.will give best answer brainlyest

Answers

Answer 1
Answer:

Answer:

Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating. So , "If air were a good conductor of heat" then soup will not stay hot for longer because this time convection+conduction will both help to transfer heat away from soup.

Explanation:
Answer 2
Answer: Convection requires the hot air just above your soup that has been heated up to rise as its density reduces after being heated, allowing the colder air around the rising hotter air to replace the hotter air and the same thing will happen again. As the convection currents (the rising of the hot air and the sinking of the cold air) keep taking place just above your soup, the previously hot soup will start to lose thermal energy (heat) and your soup will cool down despite the fact that air is a poor conductor of heat. In other words, cooling of your soup only takes place in convection due to the movement of air and not the heating up of air itself. As a result, if air was a good conductor of heat, it would not make a difference.

What is the most likely result if the shape of the enzyme changes?​
Only about 10 percent of the energy at one level of the food web is transferred to the next higher level. Most of the energy at each level is used by organisms to grow, create heat, and move. A diagram called an energy pyramid is used to display this transfer of energy. Why do you think using a pyramid shape is a good model to show how energy moves through an ecosystem?

Which was one of the main objectives of the Apollo project? A. to orbit the earth B. to land on and explore the moon C. to send the first American into space D. to build a space station

Answers

it is C because the Russians and them started a game called the space race so the Russians made to the moon 1 time and the Americans are still trying
The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which accomplished landing the first humans on the Moon from 1969 to 1972. First conceived during Dwight D. Eisenhower's administration as a three-man spacecraft to follow the one-man Project Mercury which put the first Americans in space, Apollo was later dedicated to President John F. Kennedy's national goal of "landing a man on the Moon and returning him safely to the Earth" by the end of the 1960s, which he proposed in a May 25, 1961, address to Congress. Project Mercury was followed by the two-man Project Gemini 1962–66. The first manned flight of Apollo was in 1968.

Which of the following neuronal pools leads to a long lasting output from a single input and so may be involved in higher order thinking? 1) parallel-after-discharge 2) converging 3) reverberating 4) diverging

Answers

Answer:

1) parallel-after-discharge

Explanation:

Neural circuits are defined as the connections between neurons. These neural circuits are of four types:

  1. Diverging circuits, found in sensory and motor neurons, diverge a single nerve impulse to multiple neurons in the circuit, amplifying the original signal.
  2. Convergent circuits, also found in sensory and motor pathways, converge multiple nerve impulses into a single one. These pathways are predominantly involved in inhibition and stimulation.
  3. Reverberating circuits, involved in control of sleep-wake cycle and breathing, consist of a neuron chain along which the impulse travels.
  4. Parallel after discharge, involved in cognition and mental processing, are a combination of convergent and divergent circuits. They result in an output impulse that lasts at least 15 m/s after the input impulse ends.

A star has right ascension of 35 minutes. Which of these statements is correct about the star?It is 35 minutes to the east of zero hours right ascension.
It is 35 minutes to the west of zero hours right ascension.
It is 35 minutes north of the celestial equator.
It is 35 minutes south of the celestial equator.

Answers

Answer:

the answer would be the 2nd one, or B - It is 35 minutes to the west of zero hours right ascension :))

Explanation:

its the correct answer on the quizz,,, good luck :3

Final answer:

The statement 'the star is 35 minutes to the east of zero hours right ascension' is correct. A star's right ascension (RA) is its east-west position on the celestial sphere relative to the vernal equinox, not its distance north or south of the celestial equator.

Explanation:

The right ascension (RA) of a star is akin to longitude on Earth; it tells us the east-west position of celestial bodies. However, RA is determined by the vernal equinox - the point where the celestial equator intersects with the ecliptic. If a star has a RA of 35 minutes, it means that this star is 35 minutes to the east of the zero hours point, i.e., the vernal equinox.

It's important to note that RA is not a measure of a star's distance from the celestial equator (north or south), but rather its position with respect to the vernal equinox (east or west). Therefore, the star in question is not 35 minutes north or south of the celestial equator - these would refer to its declination, not its right ascension.
