Correct Answer - (i) 0.57 (ii) 0.43

Correct Answer - (i) 0.28 (ii) 0.4 (iii) 0.32

Correct answer is (b) We know that \(\tau\) = r × F ∵ \(\tau\) \(= \frac{dL}{dt},\) \(F = \frac{dP}{dt}\) \(\left(\frac{dL}{dt}\right) = r \times \left(\frac{dP}{dt}\right)\) \(\left(\frac{dL}{dt}\right) - r \times \left(\frac{dP}{dt}\right) = 0\)

Given that \(\vec a, \vec b\) and \(\vec c\)are unit vectors. i.e., |\(\vec a\)| = |\(\vec b\)|  = |\(\vec c\)| = 1 And \(\vec a\) + \(\vec b\) + \(\vec c\) = \(\vec 0\) Then \((\vec a+\vec b+\vec c).(\vec a+\vec b+\vec c)=\vec 0.\vec...

B) Proton is represented as P-

Correct option is  C) AB < CD

Correct option is (C) 17 The smaller number is x. \(\therefore\) other number is x+5. \((\because\) One number is 5 greater than the other) Given that sum of two numbers is 29. \(\therefore\) x + (x+5) = 29 \(\Rightarrow\) 2x...
