Which of the following describes the energy emitted by the Sun in relation to time? A) Energy emitted by the Sun is constant over years. B) Energy output of the Sun varies with solar cycles. C) The energy emitted over one year equals that received in 14 seconds. D) The Sun emits energy consistently every millisecond.
Understand the Problem
The question is asking about the characteristics of the energy emitted by the Sun concerning time and how it varies or remains constant. It presents several options that discuss the nature of solar energy output over different time frames.
Answer
Energy output of the Sun varies with solar cycles.
The final answer is B) Energy output of the Sun varies with solar cycles.
Answer for screen readers
The final answer is B) Energy output of the Sun varies with solar cycles.
More Information
The energy output of the Sun changes in a nearly periodic manner, typically over an 11-year cycle influenced by the solar cycle of sunspot activity.
Tips
Students might mistake constant emission over years based on the term 'solar constant,' which actually refers to the average amount of solar energy received at a given location, not the output's consistency.
