यदि (C(t)=330-9t) और (D(t)=230-18t), तो (C(t)-D(t)) किस प्रकार बदलता है?
If (C(t)=330-9t) and (D(t)=230-18t), how does (C(t)-D(t)) change?
Explanation opens after your attempt
A. हर चरण (9) बढ़ता हैIt increases by (9) each step
Concept
(C(t)-D(t)=100+9t). Therefore the difference of the two decay models increases.
Why this answer is correct
The correct answer is A. हर चरण (9) बढ़ता है / It increases by (9) each step. (C(t)-D(t)=100+9t). Therefore the difference of the two decay models increases.
Exam Tip
(C(t)-D(t)=100+9t) है। इसलिए दोनों क्षय मॉडलों का अंतर बढ़ता है।
