It really depends on how far or close the planet is from the sun
Gravity and falling objects
Answer:
D.
Explanation:
Red light has wavelengths around 620 to 750 nm.
Answer
12.3 years
Step by step Solution
Step 1
The first step is to use the radioactive decay formula to to calculate the radioactive constant for hydrogen 3. The radioactive formula is , where is the amount available at any time, is the initial amount of substance, is the radioactive decay constant. We are given the values . We use these values to calculate the constant as follows,
Step 2
The next step is to use the value for the decay constant to calculate the half life. We notice that at the half life, the value of the material remaining is 0.5. We show the calculation as shown below,
The half life is 12.3 years.
I think the correct answer would be B. The process of elastic rebound is being shown by the student. It is a theory that is used to explain earthquakes. It focuses on how energy is being spread in times of earthquakes. As the rocks on the fault experiences shift and force, these rocks would be accumulating energy causing it to deform reaching the internal strength and eventually exceeding it. At that moment, a rapid motion would happen along the fault, which releases the energy, then the rocks would go back to its original shape or the undeformed state. This theory is the first theory that sufficiently was able to explain earthquakes.
