If the hypothesis is that frictional force increases with surface roughness which graph result would support it?यदि परिकल्पना है कि घर्षण बल सतह की खुरदरापन के साथ बढ़ता है तो कौन-सा ग्राफ परिणाम इसका समर्थन करेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Measured frictional force generally increases as roughness increasesखुरदरापन बढ़ने पर मापा गया घर्षण बल सामान्यतः बढ़े
The hypothesis predicts increasing friction with increasing roughness. Match the graph trend with the prediction.परिकल्पना बढ़ते खुरदरापन के साथ बढ़ते घर्षण की दिशा बताती है। परीक्षा में ग्राफ की प्रवृत्ति को भविष्यवाणी से मिलाएं।
