Name a machine used to reap, thresh and clean the crop.
i will give brainliest who answers first

A combine harvester, or simply a combiner, is a method of harvesting grain crops. A combination is a harvester and a thresher machine used to harvest, thresh and clean straw grain in one process. This makes the processing of crops faster and more efficient and helps farmers to harvest larger quantities.

Explanation:

umm no I don't need brianly it will be better if u follow me XD

combine harvester, or a combiner.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
