Multiple ! you can answer any one you ! i need fast! calculate the total heat content of 10 kg of ice at -23°c. (hint: a substance at absolute zero, -273o c, has 0 heat content.) 115 kcal 1300 kcal 1400 kcal 1500 kcal how much heat is contained in 100 kg of water at 60.0 °c? (hint: a substance at absolute zero, -273o c, has 0 heat content.) 30 kcal 2.10 x 104 kcal 2.40 x 104 kcal 2.77 x 104 kcal calculate the energy needed to vaporize 10.0 kg of iron (c = 0.110) initially at 2,640°c. 110 16,300

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
