Amanda and Bertha are driving race cars. The cars have equal mass. At one point in the race, they both change their speed by 10 m/s in 2 seconds. Ignore air resistance. a. Is the work done on Amanda’s car while speeding up (greater/less than/equal to) the work done on Bertha’s car while speeding up? Explain your answer b. Is the impulse on Amanda’s car while speeding up (greater/less than/equal to) the impulse done on Bertha’s car while speeding up? Explain your answer

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
