How far will the tomatoes travel horizontally by the time it hits the ground? | }^{2} \times \frac{?}{?} A ____________ experiment refers to an experiment where either the subjects,or the members of the research team measuring the response to the treatments, do not know what treatment the subjects are receiving. Now, that you have a better idea of the terminology involved in conducting an experiment, you can define the meaning of conducting an experiment as follows: Conducting an experiment is the process where researchers manipulate an explanatory variable to define treatments, which are randomly assigned to experimental units or subjects, to then compare the responses of the different groups to the treatments received. Research Scholar at Indian Institute of Technology, Roorkee, First sum applied the Newton's second law motion: F = ma, The change in temperature is 9.52CExplanation:Since, the heat supplied by the electric kettle is totally used to increase the temperature of the water.Thus, from the law of conservation of energy can be stated as:Heat Supplied by Electric Kettle = Heat Absorbed by WaterHeat Supplied by Electric Kettle = m C Twhere,Heat Supplied by Electric Kettle = 20,000 JMass of water = m = 0.5 kgSpecific Heat Capacity of Water = C = 4200 J/kg.CChange in Temperature of Water = TTherefore,20,000 J = (0.5 kg)(4200 J/kg.C) TT = 20,000 J/(2100 J/C)T = 9.52C.
