The correct expression for electric current is I = V/R, according to Ohm's law.

Mass is a fundamental quantity in the SI system.

Boron is a trivalent element that creates holes in silicon, making it a p-type semiconductor.

Electric generators utilize electromagnetic induction to convert mechanical energy into electrical energy.

Electric field lines cannot intersect because it would imply two different directions of the electric field at a point.

Intrinsic semiconductors are in their pure form without any doping.

Systematic errors are consistent and repeatable errors associated with faulty equipment or a flawed experiment design, such as zero error.

Hertz (Hz) is the unit of frequency, defined as cycles per second.

A sound wave is an example of a longitudinal wave, where the particle displacement is parallel to the direction of wave propagation.

Mass is a scalar quantity as it has magnitude but no direction.

Light waves are electromagnetic waves and are an example of transverse waves, where the oscillations are perpendicular to the direction of wave travel.

Rubber is an example of an insulator.

A balloon inflating when heated is an example of thermal expansion, as the gas inside expands with increased temperature.

Kilogram is a fundamental unit, while Newton, Joule, and Pascal are derived units.

Magnetic field is not a form of energy; it is a field that exerts a force on charged particles.

Pressure is defined as force per unit area, hence its dimension is M^1L^-1T^-2.

The dimension of velocity is M^0L^1T^-1.

The gravitational potential energy is given by U = mgh, where h is the height above the reference point.

The speed of light is approximately 3 x 10^8 m/s.

0.001 can be represented as 1 x 10^-3 in scientific notation.

Both Joule and Newton-meter represent the same unit of energy.

The unit for measuring frequency is Hertz (Hz).

The SI unit for measuring pressure is Pascal (Pa).

The SI unit for pressure is Pascal (Pa), which is equivalent to N/m².

Brittle materials fracture without significant plastic deformation.

Shear modulus (G) measures the material's response to shear stress, indicating how it deforms under such stress.

Doping is the process used to create a p-n junction by adding impurities to a semiconductor.

Uranium-238 is commonly used as fuel in nuclear reactors due to its ability to undergo fission.

Steel has the highest tensile strength among the given materials.

Copper has the highest thermal conductivity among the given materials.
