The correct answer is: B. 1 Newton metre<\/strong><\/p>\n A joule (J) is a unit of energy in the International System of Units (SI). It is defined as the work done by a force of one newton (N) acting over a distance of one metre (m).<\/p>\n A newton (N) is the SI unit of force. It is defined as the force that, when applied to a mass of one kilogram (kg), gives it an acceleration of one metre per second squared (m\/s^2).<\/p>\n A metre (m) is the SI unit of length. It is defined as the distance that light travels in a vacuum in 1\/299,792,458 of a second.<\/p>\n A kilogram (kg) is the SI unit of mass. It is defined as the mass of the International Prototype Kilogram (IPK), which is a cylinder of platinum-iridium alloy that is kept at the International Bureau of Weights and Measures (BIPM) in S\u00c3\u00a8vres, France.<\/p>\n A dyne (dyn) is a unit of force in the CGS system of units. It is defined as the force that, when applied to a mass of one gram (g), gives it an acceleration of one centimetre per second squared (cm\/s^2).<\/p>\n Therefore, one joule is equivalent to one newton metre.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”9.81 Newton metre” option2=”1 Newton metre” option3=”1 kg wt metre” option4=”1 dyne metre” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[645],"tags":[],"class_list":["post-6688","post","type-post","status-publish","format-standard","hentry","category-applied-mechanics-and-graphic-statics","no-featured-image-padding"],"yoast_head":"\n
