The force on a current-carrying conductor placed in a magnetic field is found with Fleming's left-hand rule.

Electrical energy is power multiplied by time, so the unit follows directly from the units you put in. The oven is rated 2500 W, which is 2500 divided by 1000, that is 2.5 kilowatts.

That pairing is also reflected in who hosted the outreach: Satish Chandra Dubey holds charge as Minister of State for Coal and Mines, and Rupinder Brar is Additional Secretary in the Ministry of Coal.

Representatives of diplomatic missions from nineteen countries joined the outreach interaction, among them Malawi, Sri Lanka, Mozambique, Algeria, the United States of America, Chile, Bhutan, Indonesia, Ethiopia, Russia, Iraq, Morocco, Venezuela, Spain, Poland, Mongolia, Zambia, France and Ghana, and the US Chamber of Commerce attended alongside them.

The venue and the three dates were both stated at the India Mining: Global Connect outreach meeting, where the Minister of State invited dignitaries to the opening on 15 November.

In an astronomical telescope set for normal adjustment, the magnifying power equals the focal length of the objective divided by the focal length of the eyepiece.

Speaking at the event, H. D. Kumaraswamy underlined the role of institutions such as ARAI in bridging the gap between developing a technology, validating it and getting industry to adopt it, a role that fits naturally with the mobility focus of the supported technologies.

The objective of the grant-in-aid was to support the progression of ten technologies from Technology Readiness Level 3, an early stage where a concept has been proved in the laboratory, to Level 9, where a technology is proven in its operating environment and can be sold.

The Accelerator Programme gave this amount as grant-in-aid for ten technologies, with the stated objective of moving them from Technology Readiness Level 3 to Level 9, that is, from an early laboratory stage to a product ready for the market.

Germanium is not used to build light emitting diodes because it is an indirect band gap semiconductor, so an electron falling back across the gap gives up most of its energy as heat in the crystal rather than as light.

This is the statement that is not correct, because water has a much higher surface tension than ethyl alcohol.

It is a molecule of sixty carbon atoms arranged in a closed cage of pentagons and hexagons, exactly like the panels of a football, and it is named after the architect who designed domes of the same geometry.

Ethanoic acid, better known as acetic acid and familiar as vinegar in dilute form, has the formula CH3COOH, and the -COOH group at the end is what makes it acidic, since it releases a hydrogen ion in water and turns blue litmus red.

Vegetable oils contain unsaturated chains with carbon to carbon double bonds; hydrogen adds across those double bonds in the presence of nickel or palladium, turning them into single bonds, so the oil becomes saturated and sets into a solid fat.

Going from methane to ethane, or from ethanol to propanol, adds one carbon atom of mass twelve and two hydrogen atoms of mass one each, which is fourteen in all, and it is this fixed step that defines a homologous series.

In graphite every carbon atom is bonded to only three others within a layer, so the fourth valence electron of each atom is free to move along the layer, and moving electrons constitute an electric current.

Catenation is the self-linking of atoms of the same element, and carbon shows it more strongly than any other element because the carbon to carbon bond is short and exceptionally strong, which is why chains of many carbon atoms remain stable.

When enough air reaches the burner, every carbon atom of the fuel is oxidised fully to carbon dioxide and the flame is blue and hot, giving the maximum heat for the gas consumed.

An alkyne contains a carbon to carbon triple bond, which needs at least two carbon atoms, so the series begins with ethyne, C2H2, also called acetylene and used with oxygen in welding.

The prefix di stands for two and the ending ene for a carbon to carbon double bond, so a diene is a hydrocarbon carrying exactly two such bonds; buta-1,3-diene, the raw material of synthetic rubber, is the standard example.
