Answer

The diesel car has a higher range, which allows for longer travel distances without refueling.
The diesel car's power source has a lower mass, contributing to overall weight efficiency.

Step 2

Calculate the mass of the battery as a percentage of the total mass of the electric car.

Answer

To calculate the mass of the battery as a percentage of the total mass, use the formula:

ext{Percentage of total mass} = \left( \frac{\text{mass of battery}}{\text{total mass}} \right) \times 100

Substituting the values:

\text{Percentage of total mass} = \left( \frac{420}{1610} \right) \times 100 \approx 26\%

Answer

Increasing the energy capacity allows electric cars to travel further on a single charge, enhancing usability.
Greater energy storage can reduce the frequency of recharging, improving user convenience and vehicle performance.

Step 4

Write down the equation which links energy transferred, power and time.

Answer

The equation linking energy transferred (E), power (P), and time (t) is:

E = P \times t

Step 5

Calculate the time taken to transfer 420 000 J of energy to the car battery.

Answer

Using the formula derived from the previous step:

E = P \times t

To find time (t):

t = \frac{E}{P}

Substituting the known values:

t = \frac{420000}{7000} = 60\ s
