State the difference between periodic motion and oscillatory motion.
Answer
Periodic motion repeats itself after equal intervals of time. Oscillatory motion is a to-and-fro motion about a mean position. Every oscillatory motion is periodic, but every periodic motion need not …
आवर्ती गति और दोलनीय गति के बीच अंतर बताइए।
Answer
आवर्ती गति समान समयांतराल के बाद स्वयं को दोहराती है। दोलनीय गति माध्य स्थिति के बारे में आगे-पीछे की गति है। हर दोलनीय गति आवर्ती होती है, लेकिन हर आवर्ती गति दोलनीय होना आवश्यक नहीं है। उदाहरण: वृत्…
वृत्तीय गति को दोलनीय गति क्यों नहीं कहा जाता?
Answer
वृत्तीय गति समान समयांतराल के बाद दोहराई जाती है, इसलिए यह आवर्ती है। लेकिन गति माध्य स्थिति के बारे में आगे और पीछे नहीं होती, इसलिए यह दोलनीय नहीं है। दोलनीय गति में माध्य स्थिति के दोनों ओर बार-बार…
Why is circular motion not called oscillatory motion?
Answer
Circular motion repeats after equal time intervals, so it is periodic. But the motion is not to and fro about a mean position, so it is not oscillatory. Oscillatory motion must involve repeated motion…
State the definition of period and frequency.
Answer
Period is the smallest interval of time after which motion repeats itself. Frequency is the number of repetitions per unit time. Relation: ν = 1/T, where ν is frequency and T is period.
आवर्तकाल और आवृत्ति की परिभाषा बताइए।
Answer
आवर्तकाल वह सबसे छोटा समयांतराल है जिसके बाद गति स्वयं को दोहराती है। आवृत्ति प्रति इकाई समय में दोहरावों की संख्या है। संबंध: ν = 1/T, जहाँ ν आवृत्ति है और T आवर्तकाल है।…
एक मानव हृदय 1 मिनट में 75 बार धड़कता है। इसकी आवृत्ति और आवर्तकाल ज्ञात कीजिए।
Answer
दिया है: 60 s में 75 धड़कनें सूत्र: ν = 1/T चरण 1: आवृत्ति = 75/60 s = 1.25 s⁻¹ चरण 2: ν = 1.25 Hz चरण 3: T = 1/ν = 1/1.25 s = 0.8 s उत्तर: आवृत्ति = 1.25 Hz, आवर्तकाल = 0.8 s…
A human heart beats 75 times in 1 minute. Find its frequency and period.
Answer
Given: 75 beats in 60 s Formula: ν = 1/T Step 1: Frequency = 75/60 s = 1.25 s⁻¹ Step 2: ν = 1.25 Hz Step 3: T = 1/ν = 1/1.25 s = 0.8 s Answer: Frequency = 1.25 Hz, period = 0.8 s…
