<span>The orbital period will be 5.196 earth years.
The period of an orbit is proportional to the square root of the cube of the semi-major axis. The semi-major axis of earth is 1 AU (actually 1.000001018 AU, but for this problem 1 is close enough). The hypothetical planet will have a semi-major axis of 3 AU. So making the ratios with earth's year being 1, earth's semi-major axis being 1, the planet's year being y, and the planet's semi-major axis being 3, we get the following ratio.
1 / 1^(3/2) = y / 3^(3/2)
Raise the denominators to the 3/2 powers.
1/1 = y/5.196
Multiply both sides by 5.196
5.196 = y
So the orbit period will be 5.196 earth years.</span>
The appropriate answer is a. the temperature is high enough but pressure low enough to melt iron. The earth's core is composed of two layers; the inner and outer core. Both layers are composed mainly of iron and nickel. The main difference between the two layers is that the inner core is solid and the outer core is liquid. The inner core is solid because of the pressure created by the overlaying layers; the outer core, mantle and the crust. The inner core is however hotter than the outer core.
There are several reasons that rain predictions made by meteorologists are sometimes incorrect, such as :
- Too many factors that could cause the rain
- Some of those factors could easily change in a short period of time
- We still hasn't developed a 100% solid method to make the prediction
hope this helps
Answer:
Coastal landforms are often subtle or are difficult to distinguish from other features, such as stratigraphic terraces and fault scarps, and often extend over vast areas, requiring both high-resolution imaging and regional coverage.
