Answer:
Efficiency of the machine = 75%
Explanation:
Given:
Input work = 8,000 J
Output work = 6,000 J
Find:
Efficiency of the machine
Computation:
Efficiency of the machine = [Output work / Input work]100
Efficiency of the machine = [6,000 / 8,000]100
Efficiency of the machine = 75%
<span>Suspension, chemistry definition is a heterogenous
mixture, meaning one substance is different from another, when mixed, either of
the substance (particularly the solid one), do not mix evenly. It could clearly
be seen when one mixes a solution in a suspension state because it forms a
cloudy solution, Best example of this is mud. In mud, though there is a mixture
of solid and liquid, there is still evident traces of solid particles that do
not mix evenly in the solution.</span>
Motion because the motion is the range
Let us consider the air with the index 1 and the lucite with index 2. Using the Snell's Secound Law, we have:
Entering the unknowns, remembering that the air refrective index is 1 and the lucite refrective index is 1.5, comes:
Using the arcsin properties, we get:
Obs: Approximate results, and the drawing is attached

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
