Answer:
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.
Explanation:
b. 80,000 units, because total energy remains unchanged
c. 20,000 units, because total energy of the skier decreases
d. 80,000 units, because total energy of the skier decreases
Answer:
30,000 units, because total energy remains unchanged.
Step-by-step explanation:
The law of conservation of energy states that energy cannot be destroyed, it remains conserved but transforms from one form to the other form.
Hence, we can say that
Total energy = kinetic energy (KE) + potential energy (PE).
At 100 meters above
Total energy = 0 + 50000 = 50000 units.
Hence, 60 meters, total energy would be
20,000 + x = 50000 units
Finally,
x = 50,000 - 20,000
= 30,000
The energy will only transform from one form to the other but will not change.
B. specific heat
C. freezing point
D. solubility
