A spring with a spring constant of $10000 \, N/m$ is stretched by $2 \, cm$ from its equilibrium position. What is the magnitude of the restoring force exerted by the spring?

In a specific heat capacity experiment, if heat is being lost to the surroundings, how will the calculated specific heat capacity compare to the actual value?

What is the reading accuracy of a Vernier caliper?

If the heat capacity of a substance of mass $10 \, \text{g}$ is $3 \, \text{J/K}$, what is the heat capacity of $100 \, \text{g}$ of the same substance?

A converging lens of focal length $f$ will act as a simple microscope when the object is placed in which region?

In an experiment to verify Hooke's law, if the applied force ($F$) is plotted against the extension ($e$), what does the slope of the resulting graph represent?

The copper lid of a calorimeter prevents heat loss primarily by which mode of heat transfer?

In the simple pendulum experiment, if $T^2$ is plotted against $L$, the relationship is $T = 2\pi\sqrt{L/g}$. What will be the slope of the graph?

A graph of $1/u$ against $1/v$ is plotted for a convex lens. From what part of the graph can the focal length ($f$) be deduced?

In an experiment to determine the moment of inertia of a cylindrical rod, which instrument is typically used to measure the diameter of the rod accurately?
