Answer Choice “A.” is the most sequentially correct answer choice from my understanding. Binding must occur before the making of mRNA, so Answer Choices C and D can be eliminated immediately. If the RNA Polymerase would detach from the DNA before, then how would it make mRNA? That’s when we are left with Answer Choice A, which seems like the best Answer Choice.
Expense of running an electric appliance for 2 hours is 1.32 $.
Explanation:
Power is defined as the energy consumed or converted or heat transferred per unit time. Its actually equationally described as energy divided by the time.
In the question, the appliance is consuming electricity at 110 volts and 30 amps.
So the power consumed in 1 hour = = 3300 watts.
So the energy consumed in 2 hours = = 6600 watt hours. =6.6 kilowatt hours.
So expense at the rate of 0.2 $ per hour = $ = 1.32 $.
