Answer:
1. flame color (i think)
2. carbon dioxide is a reactant
Answer:
Wet Cell Disadvantages
Wet cell batteries are potentially more dangerous and slower to charge than AGM batteries.
Wet cells emit hydrogen gas during normal operation and especially during charging.
F=.25
So the answer would be C
Answer: CO2 levels are high in the first half of the year, low in the second half(but increasing on average over time)
SEE BELOW for the rest
Explanation:
concepts
photosynthesis uses light, CO2 and H2O to produce glucose and O2
Respiration uses glucose and O2 to produce CO2 and H2O and energy
Reasoning
this is northern hemisphere data. Winter and colder weather, and winter-deciduous trees reduce removal of CO2 from the atmosphere. The second half of the year is influenced by summer, with high growth rates and high CO2 uptake, reducing atmospheric levels
Answer:
The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.
Explanation:
As learned above, the amount of air resistance depends upon the speed of the object. ... Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
