Answer:
C. Energy is used for life processes (e.g. Movement, breathing, etc.)
Explanation:
As we pass from one trophic level to the next, only 10% of energy is transferred from the first trophic level to the next. This is because a lot of energy is lost to the surroundings and rest is utilised by the organism.
Explanation:
Displacement is the shortest distance between two points. Displacement is used to calculate vector quantities such a velocity, force, acceleration, etc.
Here, Maria drove to the store and then to work this means that her total displacement will be the minimum distance between her initial point and her work place.
Hence, the minimum distance between her initial point and her work place is her total displacement.
Answer:
C.
Explanation:
Exothermic refers to a RELEASE of energy through a reaction(usually chemical). When salt dissociates, polar water molecules pull apart ions, releasing energy.
Answer:
force is a push or a pull
The caravan has an initial speed of
85 km/h × (1000 m/km) × (1/3600 h/s) ≈ 23.611 m/s
If it slows down at a constant rate, then it will cover a distance <em>x</em> such that
0² - (23.611 m/s)² = 2 (-1.3 m/s²) <em>x</em>
Solve for <em>x</em> :
<em>x</em> = -(23.611 m/s)² / (2 (-1.3 m/s²)) ≈ 214.417 m ≈ 210 m
