Answer:
The bee's energy output can be calculated directly, and related to its size. it only needs enough air resistance to counter its weight and enough power in its wings to sustain this resistance. it bee like that.
Distance and displacement are two quantities that may seem to mean the same thing yet have distinctly different definitions and meanings.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Answer:
The answer to your question is: Arrhenius base
Explanation:
Arrhenius base ; an Arrhenius base is able to produce (OH-) in water, so Ca(OH)2 is an Arrhenius base.
Brønsted-Lowry base
. An Bronsted and Lowry base is able to accept a proton, Ca(OH)2 can do it.
Lewis base
this base is able to donate a pair of electrons, Ca(OH)2 does not have a pair of electrons to donate.
All of the above. This option is wrong only the first option is correct.
Answer:
Heat is absorbed.
Explanation:
Endothermic reactions: Heat is absorbed.
Answer: True
Explanation:
Air is indeed a mixture as the component compounds and mixtures retain their individual properties as opposed to a compound that sees the component elements lose some of theirs.
Air is a type of mixture known as a homogeneous mixture which means that no matter what quantity of air is present, the composite elements (Oxygen, nitrogen etc) and compounds( carbon dioxide etc) are of the same quantity.
