i) The velocity before heating the ground. (1 mark)
ii) The kinetic energy by the time of heating the ground. (2 marks)
d) Calculate the refractive index of water given that the velocity of light through water is .

Give me some answer choices and i will be happy to

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 !

Ai think hope that
