Answer: I= 0.583A
R=205.83ohms
Explanation: Power= I*V
Where I= current and V = potential difference
I=P/V
I= 70/120
I=0.583A
To find resistance
Using ohms law
V= IR
R=V/I
R= 120/0.583
R= 205.83ohms
Radio Station W as the slower the frequency the longer the wave length
Answer:
final temperature will be 0 degree C
Total amount of ice will be
total amount of water
Explanation:
After thermal equilibrium is achieved we can say that
Heat given by water = heat absorbed by ice cubes
so we will have
Heat given by water to reach 0 degree C
heat absorbed by ice cubes to reach 0 degree
so we will have
so here we can say that few amount of water will freeze here to balance the heat
so final temperature will be 0 degree C
Total amount of ice will be
total amount of water
