Answer:
C
Explanation:
It has to travel 600 light years before we would be able to observe the explosion.
Answer:
A. 112 J
Explanation:
KE = ½mv² = ½(0.14)40² = 112 J
1. F = 8 Hz
2. V = 8 m/s
3. D = 8 m
4. T = 8 sec
Slowly; Boiling Point; Decrease; Decrease; Vibrate in place.
As temperature drops, so does thermal energy, and particle motion drops. The same trends in temperature, thermal energy, and motion applys to phases in decreasing order: gas>liquid>solid. The particle motion is always vibrations in place for solids because they are very tightly packed compared to liquids and gases.
