To solve this problem we will apply the Wien displacement law (in honor of Wilhelm Wien) which is a law of physics that states that there is an inverse relationship between the wavelength at which the emission peak of a body occurs Black and its temperature. Mathematically, the law is:
Here,
T = Temperature
We know at the same time that the range of red to infrared wavelength is
Calculating each quasi infinite point of this range would be somewhat complex, so it is easier to replace temperatures and see if the temperature falls on the range. We can realize that the first option is the correct one, because:
Therefore the temperature is A. 3500K
Answer:
1) Unbalanced
2) Balance
3) Balanced
4) Unbalanced
5) Unbalanced
Explanation:
For 1 and 5, since the objects are not at a constant speed/velocity, their forces must be unbalanced.
For 2 and 3, their speeds are constant so that means the force is balanced. If the bycicle or box started accelerating, that would indicate an unbalanced force
For 4, the speed is constant, but it's direction is not indicating another unbalanced outside force causing it to turn. The force is unbalanced.

Complete option to the question:
A. The asthenosphere is broken up into large continental- and ocean-sized plates.
B. Convection currents within the asthenosphere push magma upward to create new crust.
C. Heat from deep within Earth is thought to keep the asthenosphere malleable.
D. The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.
Answer: The correct option is A (The asthenosphere is broken up into large continental- and ocean-sized plates.)
Explanation:
Among the components that makes up the earth crust are the lithosphere and the asthenosphere.
The LITHOSPHERE is the outer layer of the earth structure which consists of the upper part of the mantle and the crust.
The ASTHENOSPHERE is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is denser and weaker layer of the upper mantle which permits the movement of tectonic plates in the lithosphere.
The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.Heat from deep within Earth is thought to keep the asthenosphere malleable. And the convection currents within the asthenosphere push magma upward to create new crust. But it is not broken up into large continental- and ocean-sized plates.
