Answer:
Western north america
Explanation:
extending from southern British Columbia through Washington and Oregon to North Calfirona
Answer: 83%
Explanation:
Efficiency of the process = work output/work input × 100%
Work input is the energy used up in the process = 720,000Joules
Work output = Force × distance
= (3000×10)× 20
= 600000 Joules
Efficiency= 600000/720000 × 100
= 0.83×100
= 83%
Answer:
If the temperature of the earth rises, the planet rapidly emits an increasing amount of heat to space. The atmosphere and the surface of the earth together absorb 71 percent of incoming solar radiation, so together, they must radiate that much energy back to space for the planet's average temperature to remain stable.
Answer:
accerlation gravity =Force/mass
g=479.96/129.72
g=3.699≈3.7 m/s²
