Answer:
An example of a shortage is limited amounts of food available because the trucks carrying it are on strike. Shortage is when there is excess demand but the supply is limited. In the other choices, the definition of shortage cannot be seen.
Answer and Explanation:
The three types of heat transfer are called conduction, convection and irradiation.
Conduction occurs with the contact between two bodies and with the agitation of the molecules. Warmer bodies have molecules in intense agitation. When a colder body comes into contact with that warmer body, the movement of molecules in the hot body affects the movement of molecules in the colder body, causing the heat between the two bodies to be shared.
Convection occurs in liquids and gases. This type of heat transmission occurs through circular currents, called convection currents, these currents are created through the difference in density between the coldest part of a liquid or gas and the warmest part. These currents cause the warmest, least dense part to rise, while the coldest and most dense part go down. This cycle is repeated several times, until all the liquid or gas has the same temperature.
Irradiação: Essa transmissão de calor é feita através das ondas eletromagneticas que são liberadas por qualquer corpo que possui temperatura. Essa transmissão de calor não necessita de contato direto entre os corpos, já que essas ondas se propagam através do espaço, até mesmo no vacuo.
Answer:
During WWI (1914-1918), large numbers of women were recruited into jobs vacated by men who had gone to fight in the war. ... The high demand for weapons resulted in the munitions factories becoming the largest single employer of women during 1918.
