FAQ
Q: What does direct proportionality mean?
A: Direct proportionality refers to the relationship between two quantities that increase or decrease in the same ratio.
Q: What is the constant of proportionality 'k'?
A: The constant of proportionality 'k' is the value by which one quantity needs to be multiplied to get the other quantity in a direct proportionate relationship.
Q: Can you provide an example of calculating the constant of proportionality in the context of color printing?
A: In the context of color printing, if the cost of printing 50 pages is $20, then the constant of proportionality 'k' would be $0.40 per page.
Q: How is the general expression for direct proportionality defined?
A: The general expression for direct proportionality is y = kx, where 'y' represents one quantity, 'x' represents the other quantity, and 'k' is the constant of proportionality.
Q: What is the concept of nuclear fusion?
A: Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
