What happened to the scientists' estimates of the Earth's age in the year 1650 since then the scientists now think the earth is much older. Currently Earth's age is approximately <span>4.543 billion years. Thank you for posting your question here. I hope the answer helps. </span>
Answer:
The value is 
or 21.45%
Explanation:
From the question we are told that
The first reservoir is at steam point 
The second reservoir is at room temperature 
Generally the maximum theoretical efficiency of a Carnot engine is mathematically evaluated as
=> 
=>
<span>System B: The amorphous silicon solar modules have an efficiency of 6%. The dimensions of the solar modules amount to 0.5m by 1.0m. The output of each module is 30 Wp. The modules cost 20€ each. The advanage of the amorphous silicon solar modules is that they perform better on cloudy days in which there is no direct sunlight. Installed in the Netherlands, this system gives, on a yearly basis, 10% more output per installed Wp than the multicrystalline silicon modules. </span>
<span>System A: The efficiency of the multicrystalline silicon module amounts to 15%. The dimensions of the solar module are 0.5m by 1.0m. Each module has 75 Wp output. The modules cost 60€ each.

Explanation:
If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the
• Magnitude if each charge, q1 and q2
• Sign of each charge (+ or -)
• Distance between the charges, r
This is essentially Coulomb’s Law:
FE = (kq1q2)/r2
For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
Answer:
Callisto. As Io is geologically active body.
Explanation:
Io and Callisto are 2 of the Galilean moons of Jupiter. Io is most geologically active body in the solar system which means that a lot of volcanic activity takes place over there whereas Callisto is not geologically active.
This is the reason that probability of finding an impact crater will be more on Callisto than Io. As the craters might get filled with volcanic eruptions.
