Answer:
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
Explanation:
becuse
It would have 8 joules because if the box is going half the speed with the same mass the you would just divide the joules in half
Answer:
c)both
Explanation:
The laws of reflection hold true for all the reflecting surfaces either spherical or plane. Therefore, the plane mirror, concave mirror and the convex mirror all will follow the laws of reflection.
Let us assume that the definition of frequency, wavelength and wave speed is determined by the function

Here,
v = Velocity of wave
= Wavelength
f = Frequency
We know that the earth has the ability to absorb visible light but that it can also emit a longer radiation wavelength. This assessment allows us to confirm that option A. Is correct. In turn, if said wavelength is large, being inversely proportional to the frequency,

This does tend to be lower radiation. The correct options are:
A.The earth absorbs visible light and emits radiation with a longer wavelength.
B.The earth absorbs visible light and emits radiation with a lower frequency.
Answer:
True.
