Answer:
Back away from the situation and tell the supervisor/teacher
The refractory period makes the cell rest. In this period, the cell becomes able to depolarize again by collecting ions.
Answer:
The likely causes inferred about the differences in times observed are;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water
Explanation:
The factors that affect the boiling point of water includes;
1) The amount of heat supplied, to the water
2) Vapor pressure above the water surface
3) Presence of impurities in the water
Therefore, the most likely causes for the difference in the times observed for the water to boil in the order of increasing probability of cause and effect are therefore;
1) Slight increase of the vapor pressure of the air immediately above the water surface due to the presence of a lid
2) Variation of heat input due to wind draft that alters the focus of the flame
3) The introduction of impurities into the water from the water source or through the sourcing mediums or containers or during handling of the water.
Answer:
Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole."
