Answer:
Explanation:
for earth -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₁² x solar constant on earth , R₁ is distance between earth and sun.
for marsh -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₂² x solar constant on Mars , R₂ is distance between earth and sun.
from two equation ,
4π R₂² x solar constant on Mars = 4π R₁² x solar constant on earth
solar constant on Mars = (R₁ / R₂ )² x solar constant on earth
Answer: hello your question is incomplete below is the missing part
A 69-kg petty thief wants to escape from a third-story jail window. Unfortunately, a makeshift rope made of sheets tied together can support a mass of only 58 kg.
answer:
To 2 significant Figures = 1.6 m/s^2
Explanation:
<u>Calculate the magnitude of minimum acceleration at which the thief can descend </u>
we apply the relation below
Mg - T = Ma --- ( 1 )
M = 69kg
g = 9.81
T = 58 * 9.81
a = ? ( magnitude of minimum acceleration)
From equation 1
a = [ ( 69 * 9.81 ) - ( 58 * 9.81 ) ] / 69
= 1.5639 m/s^2
To 2 significant Figures = 1.6 m/s^2
Similar chemical behavior. All the members of a group of elements have the same number of valence electrons and similar chemical properties.
