Study the following question carefully and choose the right answer.
Statement: Should articles of only deserving authors be allowed to be published?
Arguments: \[\begin{array}{|c|l|}\hline (I) & \text{No, it is not possible to draw a line between the deserving and the undeserving.} \\ \hline (II) & \text{Yes, it will save a lot of paper which is already in short supply.} \\ \hline \end{array}\]
Step 1: Analyze argument (I).
The first argument states that it is not possible to draw a clear line between deserving and undeserving authors, which is a valid concern. However, this does not provide a clear solution to the problem. It is more of a neutral statement and not a strong argument in favor of publishing only deserving authors.
Step 2: Analyze argument (II).
The second argument states that publishing only deserving authors will save paper, which is true. But the reasoning does not seem appropriate for the question, as it does not address the core issue of how deserving authors are identified. Hence, it is not a strong argument either.
Step 3: Conclusion.
Since both arguments do not provide strong support for the statement, the correct answer is that neither argument is strong.
Final Answer: \[ \boxed{\text{Neither I nor II argument is strong.}} \]
A weight of $500\,$N is held on a smooth plane inclined at $30^\circ$ to the horizontal by a force $P$ acting at $30^\circ$ to the inclined plane as shown. Then the value of force $P$ is:
A steel wire of $20$ mm diameter is bent into a circular shape of $10$ m radius. If modulus of elasticity of wire is $2\times10^{5}\ \text{N/mm}^2$, then the maximum bending stress induced in wire is:
