Answer:

A neon sign

Explanation:

Luminescence is spontaneous emission of light by a substance not resulting from heat; or "cold light". It is thus a form of cold-body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions or stress on a crystal.

VLD [36.1K]

Answer:

I think this is already answered.

Explanation:

Gomez has an evening class after ballet practice. He tries to stay alert in class, but his instructor tends to speak in a monotone voice, which makes it difficult for Gomez to focus. One strategy to remain attentive would be to show empathy, respect, and genuine interest in the lecture predict and ask questions show that he is listening focus on ballet.

The weight Lucy lost with respect to number of weeks was recorded for six weeks. The correlation coefficient was calculated to b
Aleonysh [2.5K]

Answer: There is a weak, positive correlation between the weight Lucy lost and the number of weeks.

Explanation:

The correlation coefficient is used to measure the relationship between two variables in terms of how they move in relation to one another.

If two variables are said to have a positive correlation, it means that they increase at the same time and decrease at the same time for example, there is a positive correlation between the amount of food a family buys and how much money they have because the more money they have, the more food they buy.

Negative correlations are the reverse for instance Ice cream sales and cold temperatures. The colder it is, the less people buy ice cream.

The Correlation coefficient ranges from -1 to +1 with +1 (-1) meaning that the variables are perfectly positively(negatively) correlated. The closer the value is to 0, the weaker the correlation.

Generally, for a correlation coefficient between the numbers 0 and +0.3, there is a weak positive correlation.

With a correlation coefficient of 0.0502, there is therefore a weak, positive correlation between the weight Lucy lost and the number of weeks.

Which of hubbie’s findings supported the Big Bang theory? Check all that apply
poizon [28]

Answer:

  1. There are billions of galaxies in the universe, not just one.
  2. The universe formed from a central point.
  3. Most galaxies in the universe are moving away from Earth.

Explanation:

  • Hubble's theory is a model of the observable universe and represents the earliest form of evolution of the universe in the form of a big bang. The process of large-scale evolution and origin and growth of the universe.
  • It explains the development of the universe from an ingle bang where all the galaxies spread and are still growing further apart from each other.
  • It explains the formation of the university from a single point in the history of time. It also explains the formation of galaxies in the universe such as those of the spiral and elliptical ones. How the galaxies and planets came into the formation from this one single point.

Explain each of the five theories of emotion (James-Lange, Cannon-Bard, Schachter-Singer two-factor theory, Zajonc and LeDoux, a
hoa [83]

Answer:

The James-Lang theory states that our experiences of emotion is our awareness of our physiological responses to emotion-arousing stimuli, meaning that your body does certain thing which is then followed by an emotion. For example, your heart racing, and body shaking would be followed by a sudden rush of fear. 

The Cannon-Bard theory states that an emotion arousing stimulus simultaneously triggers a physiological response and the subjective experience of an emotion. Disagreeing with the James-Lang theory, the Cannon-Bard suggests that the feeling of fear does not cause your heart rate to increase but your heart rate increasing, does not evoke a feeling of fear, rather, these are both separate occurrences that happen simultaneously.

The two-factor theory states that to experience emotion, you must be physically aroused and cognitively label the arousal. This means that in order to feel an emotion you have to be consciously aware of the stimuli provoking and causing the emotion. 

The Zajonc, LeDoux, and Lazarus theory states that some emotions can occur instantly with out conscious appraisal.
