Answer:
The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems
Hello!
The name for continents in one landmass surrounded by gigantic ocean is Pangaea.
This name is originated from the Greek words Pan ("all") and Gaia ("Earth"). It describes the supercontinent that would have existed in the Cenozoic and Mesozoic periods by the joining of all continents that we know them today.
The gigantic ocean that surrounded it is called Panthalassa, from Greek Pan ("all") and thálassa ("sea").
Have a nice day!

Answer:
The average current that this cell phone draws when turned on is 0.451 A.
Explanation:
Given;
voltage of the phone, V = 3.7 V
electrical energy of the phone battery, E = 3.15 x 10⁴ J
duration of battery energy, t = 5.25 h
The power the cell phone draws when turned on, is the rate of energy consumption, and this is calculated as follows;
where;
P is power in watts
E is energy in Joules
t is time in seconds
The average current that this cell phone draws when turned on:
P = IV
Therefore, the average current that this cell phone draws when turned on is 0.451 A.
