Final answer:
We use the Stockholders' Equity Ratio (SGR) to estimate a company's sustainable growth without additional financial leverage and the Specific Absorption Rate (SAR) to measure how much radiofrequency energy is absorbed by the body from wireless devices.
Step-by-step explanation:
When making financial or investment decisions, we use both the Stockholders' Equity Ratio (SGR) and the Specific Absorption Rate (SAR). The SGR, or Sustainable Growth Rate, is a financial indicator used to estimate the growth in a company's earnings and dividends that can be sustained without having to increase financial leverage. On the other hand, the SAR refers to the Specific Absorption Rate, which is a completely different concept and relates to the rate at which the body absorbs radiofrequency energy from wireless devices, and is not associated with financial matters.
The SGR is particularly useful for businesses and financial analysts to understand how a company can grow using internal resources without needing to take on additional debt. Meanwhile, SAR is critical for health and safety regulators and manufacturers of electronic devices, ensuring products comply with legally mandated safety limits of exposure to electromagnetic fields.
