Answer:
a. C₄H₁₀/O₂ = 2:13 (example)
b. O₂/CO₂ = 13:8
c. O₂/H₂O = 13:10
d. C₄H₁₀/CO₂ = 2:8
e. C₄H₁₀/H₂O = 2:10
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O
The molar ratios are the same as the coefficients in front of the formulas.
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.

Explanation:
A. Local winds occur over a small area, while global winds occur over a large area.
B. Local winds blow in from the ocean, while global winds do not.
C. Local winds are considered breezes, while global winds produce mostly storms.
D. Local winds are created by the unequal heating of Earth's surface, while global winds are produced by polar temperature zones.
Conduction occurs when heat is transferred into an object through motion or movement
