A wheel turns (42) radians in (7) seconds. Through how many degrees will it turn in (3) seconds?एक पहिया (7) सेकंड में (42) रेडियन घूमता है। (3) सेकंड में वह कितने डिग्री घूमेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{1080^\circ}{\pi} )( \frac{1080^\circ}{\pi} )
The rate is (6) radians per second, so in (3) seconds it turns (18) radians, which is (18\cdot\frac{180^\circ}{\pi}=\frac{3240^\circ}{\pi}).दर (6) रेडियन प्रति सेकंड है इसलिए (3) सेकंड में (18) रेडियन यानी (18\cdot\frac{180^\circ}{\pi}=\frac{3240^\circ}{\pi}) है।
