It changes because radiation always differs in the atmosphere because of the nuclear plants and of pollution around us. Even though it is indoors.
The appropriate answer is c. evaporation. Evaporation is the process by which a liquid changes to a gas and in this case is the best way to remove the water from the homogenous mixture. The reaction can be sped up by heating the mixture. All the water will eventually evaporate leaving behind the sodium chloride crystals as a precipitate.
Filtration works best on mixtures that have precipitates and distillation is for separating liquids with different boiling points.
Answer:
what is Jose potential energy
Answer:
The magnitude of average emf is 9.813 mV.
Explanation:
Given that,
Number of turns = 25 turns
Diameter = 1.00 m
Magnetic field = 50.0μm
Time = 0.200 s
Angle = 180°
We need to calculate the area of the coil
Using formula of area
We need to calculate the average emf
Using formula of emf
Where, N = number of turns
A = Area
B = magnetic field
Put the value into the formula
Hence, The magnitude of average emf is 9.813 mV.
Answer:
Scenario A, B and E is True.
Explanation:
Scenario A) True. Removing carbon dioxide from atmosphere decreases greenhouse effect of atmosphere. Thus, temperature rise decreases.
Scenario B) True. The more evaporation creates the more greenhouse effect. Therefore, temperature rise increases.
Scenario C) False. Removing carbon dioxide from atmosphere decreases greenhouse effect of atmosphere. Thus, temperature rise decreases.
Scenario D) False. The more evaporation creates the more greenhouse effect. Therefore, temperature rise increases.
Scenario E) True. If reflected radiation increases from Earth, temperature rise of the Earth will decrease. Ice cover increases reflectivity which leads temperature level decrease.
Scenario F) False. If reflected radiation increases from Earth, temperature rise of the Earth will decrease. Ice cover increases reflectivity which leads temperature level decrease.
