xeze [42]

Answer:

Almost 3 snicker's bar will contain the worth of energy stored in the battery which makes option A correct (Fewer than 5)

Explanation:

Step 1

The energy stored in a charged battery is 840 Watt- hours

Recall from the question that 1 KWh = 3600 KJ

So how many Kilo-joules will be in 840 Watt- hours?

I will convert 840 Watt- hours to KWh = 840 / 1000

                                                              = 0.840 KWh

Since I KWh gives 3600 KJ

then, 0.840 KWh will give x

                                          x = 3024 KJ

3024 KJ of energy is stored in the battery

Step 2

A snicker bar contains 250 cal and 1 cal = 4.184 KJ

Convert 250 cal to KJ?

250 cal = 1046 KJ

Each snicker bar contains 1046 KJ

To calculate how many snicker's bar worth energy stored in the battery will be (y) ?

y = 3024 / 1046

y = 2.9 snicker's bar approximately 3

The correct option is Fewer than 5
