Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.

For resistors in series in a DC circuit, the potential difference is proportional to the resistance.
The voltage V across the 7.1 ohm resistor can be found from the proportion
V/7.1 = 12/4.8
V = 7.1*12/4.8 = 17.75
The potential difference at the battery terminals is the sum of the potential differences across the two series resistors.
Vbatt = 17.75 V + 12 V
Vbatt = 29.75 V
Answer:
Time taken to reach your destination will be 10hours
Explanation:
Recall the formula for Speed;
speed=Total distance/Total time taken
Speed=2km/h
Total distance=20km
Time taken=x
let x be the unknown time taken
Input each values into the formula;
2=20/x
Making x subject of the equation
x=20/2
x=10
Total time taken =10hours.
Answer:
Hope this helps you find the answer
Explanation:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
