Diagonal = √[(4-0)² + (3-0)²] = √[16 + 9] = √25 = 5.

Length of diagonal = √[(4-0)² + (3-0)²] = √[16 + 9] = √25 = 5.

Diagonal length = √[(5-1)² + (4-1)²] = √[16 + 9] = √25 = 5.

The magnetic field around a long straight wire is given by B = (μ₀I)/(2πr).

The magnetic field at the center of a circular loop carrying current is directly proportional to the current and inversely proportional to the radius.

The magnetic field inside a long solenoid is uniform and directed along the axis of the solenoid when it carries a current.

The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid.

The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid when the current is steady.

The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid.

Elastomers are characterized by their elastic properties, allowing them to stretch and return to their original shape.

Natural rubber is primarily composed of polyisoprene, which is derived from latex.

Lipids serve as a major form of energy storage in the body.

The main products of the combustion of hydrocarbons are water (H2O) and carbon dioxide (CO2).

The complete combustion of ethane produces carbon dioxide and water as the main products.

The complete combustion of methane (CH4) produces carbon dioxide (CO2) and water (H2O).

The main product of the oxidation of ethanol is acetic acid.

The reaction of 1-bromobutane with sodium hydroxide in ethanol leads to elimination, forming butene as the main product.

The reaction of an amine with an acyl chloride produces an amide.

The main product is a quaternary ammonium salt when an amine reacts with an alkyl halide, as the amine can be further alkylated.

The reaction of ethene with bromine results in the formation of 1,2-dibromoethane.

The main product is ethane, formed by the hydrogenation of ethene.
