यदि परिकल्पना है कि घर्षण बल सतह की खुरदरापन के साथ बढ़ता है तो कौन-सा ग्राफ परिणाम इसका समर्थन करेगा?
If the hypothesis is that frictional force increases with surface roughness which graph result would support it?
Explanation opens after your attempt
C. खुरदरापन बढ़ने पर मापा गया घर्षण बल सामान्यतः बढ़ेMeasured frictional force generally increases as roughness increases
Concept
The hypothesis predicts increasing friction with increasing roughness. Match the graph trend with the prediction.
Why this answer is correct
The correct answer is C. खुरदरापन बढ़ने पर मापा गया घर्षण बल सामान्यतः बढ़े / Measured frictional force generally increases as roughness increases. The hypothesis predicts increasing friction with increasing roughness. Match the graph trend with the prediction.
Exam Tip
परिकल्पना बढ़ते खुरदरापन के साथ बढ़ते घर्षण की दिशा बताती है। परीक्षा में ग्राफ की प्रवृत्ति को भविष्यवाणी से मिलाएं।
