Steel has the highest tensile strength among the given materials.

Copper has the highest thermal conductivity among the given materials.

Silicon is a common intrinsic semiconductor used in electronic devices.

Copper is a good conductor of electricity due to its high number of free electrons.

Glass is commonly used as a dielectric material in capacitors due to its high dielectric constant and insulating properties.

Iron is a ferromagnetic material, which means it can be magnetized and retains its magnetic properties.

Copper is a good conductor of electricity due to its low resistance and high conductivity.

Conduction is a mode of heat transfer and is not associated with wave phenomena.

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Melting involves a change of state (solid to liquid) without a change in temperature.

Beta decay involves the emission of a positron, which is the antimatter counterpart of an electron.

Convection is the process that involves the transfer of heat through a fluid (liquid or gas) due to the movement of the fluid itself.

Convection involves the transfer of heat through the movement of fluids.

Area has dimensions of M^0L^2T^-2.

Angle is a dimensionless quantity.

Velocity has the dimension M^0L^1T^-1.

Work has the dimension M^1L^2T^-2.

Displacement is a vector quantity as it has both magnitude and direction, while speed, distance, and mass are scalar quantities.

In an isolated system, energy, momentum, and mass are all conserved.

The azimuthal quantum number (l) describes the shape of the atomic orbital.

Systematic errors are consistent and repeatable inaccuracies, often due to calibration errors.

Significant figures include all non-zero digits and any zeros between them or trailing after a decimal point.

Electric current is defined as the flow of electrons in a conductor.

Sound waves require a medium (solid, liquid, or gas) to travel and cannot propagate through a vacuum.

Surface tension is a property of liquids that causes them to minimize their surface area, allowing them to form droplets.

The critical angle is defined as the angle of incidence above which total internal reflection occurs, and it is always less than 90 degrees.

The image formed by a plane mirror is virtual, erect, and located behind the mirror at the same distance as the object.

The magnetic field due to a current-carrying loop is strongest at the center of the loop and decreases as you move away from the center.

The magnetic field due to a long straight conductor decreases with increasing distance from the conductor.

Inside a long solenoid, the magnetic field is uniform and parallel to the axis of the solenoid, provided the solenoid is long enough.
