Answer:
When the heat is heated it will be melted of ice, why it still remain at a constant temperature of 0◦ C.
Explanation:
Solution
The heat given by the heater will be used in melting of the ice, therefore the temperature will remain the same at the degree of 0◦ C.
After the ice is fully melted, the temperature of water will begin to increase with time.
Note: kindly find an attached document of the solutions with diagrams as part of this explanation
We will use formula for the orbital velocity of Venus, which is v = 35.02 km/s.
An average distance to the Sun ( In kilometers ) is:
R = 0.723 * 149,579,871 km= 108,150,260 km.
Than we will calculate the orbital period ( T ).
v = 2 π R / T
T = 2 π R / v
T = 2 * 3.14 * 108,150,260 km / 126,072 km/s
T = 5389.75 s ≈ <span>224.5 days
The orbital period of Venus is approximately 224.5 days.</span>
