Then, what does petajoules mean?

petajoule. Noun. (plural petajoules) (metrology) An SI unit of energy, work, and heat equal to 1015 joules.

Also, how much energy is a Petajoule?

The joule is the standard unit of energy in general scientific applications. One joule is the equivalent of one watt of power radiated or dissipated for one second. One petajoule is 1015 joules (1 million billion) or 278 gigawatt hours.

What is joules formula?

In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.

Is it PJs or pj's?

Here's the lowdown on nightwear, plurals and otherwise, courtesy of Merriam-Webster's Collegiate Dictionary: “pajama”; “pajamas”: the standard American spelling. “pj”; “pj's”: the standard singular and plural abbreviations.

What is a mega joule?

Megajoule is a unit of energy equal to 1 000 000 joules, symbol "MJ". This unit comes from a combination of metric-prefix "mega" and SI derived unit of energy "joule". Plural name is megajoules.

How is coal formed?

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

What is velocity formula?

Velocity Formula. The velocity is the time rate of change of displacement. If 'S' is the displacement of an object in some time 'T', then the velocity is equal to, v = S/T. The units of velocity are m/s or km/hr.

What is Joule's first law?

Joule's laws are two: first about heat produced by an electric current, and second about how the energy of a gas relates to pressure, volume. Joule's first law shows the relation between heat generated by an electric current flowing through a conductor.
