Answer: One of the signs a chemical reaction is taking place is the presence of bubbles. :)
They move in a waves motion
Answer:
Mass doesn't change.
Weight is measured based on gravitational pull.
Explanation:
<h2> The potential and kinetic energy of airplane are affected by these factors </h2>
Explanation:
When airplane rises up , it requires potential energy . This potential energy can be taken from the kinetic energy of airplane .
Thus if the speed of wind is larger , it can either oppose the motion of velocity or can favour the velocity of airplane . By which its kinetic energy is effected .
If the weight of airplane is changed , it will effect the potential energy required . Thus heavier plane requires higher potential energy for attaining the same height .
Thus these two factor has important role in the flight of airplane .
Unicellular: An organism that consists of a single cell
Multicellular: An organism with multiple cells
Eukaryotic: A cell that contains a nucleus
Prokaryotic: A cell with no nucleus
Autotrophic: An organism that has the ability to make their own food
Heterotrophic: Organism that cannot create their own food
Asexual reproduction: When an organism has the ability to create offspring without the help of another organism
Sexual Reproduction: When two organisms create an offspring using the gametes
