Answer:
149,700,000 km (= 1.50 x 10⁸ km)
Explanation:
Given,
Speed of light, c = 300,000 km/s
Time Taken = 8 min 19 s = 499 seconds
Recall, Distance = Speed x Time
= 300,000 km/s x 499 s
= 149,700,000 km
= 1.50 x 10⁸ km
Answer:
C. 167 kJ
Explanation:
The minimum amount of heat require to complete turn the ice into liquid water is equal to the latent heat of the ice, that is, the amount of heat needed by the ice to turn into water. This amount is calculated by:
(1)
Where:
- Mass of ice, measured in kilograms.
- Latent heat of fusion, measured in kilojoules per kilogram.
- Latent heat, measured in kilojoules.
If we know that and , the latent heat of ice is:
Therefore, the correct answer is C.
Im pretty sure the answer is B Energy
Player #2 has the most momentum. Think it as if you are rolling a baseball, bowling ball, and softball down a hill. it will take more effort to stop the bowling ball, because it has more momentum.
