An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To complete the sentences, we need to unscramble the letters to form the correct words that fit in each sentence. Let’s go through each sentence:
'The colourful kite ______ high in the sky. (deails)'
The correct word that fits here is 'sailed' . So, the sentence becomes: 'The colourful kite sailed high in the sky.'
'The airplane ______ past the bird. (ildedg)'
The correct word is 'glided' . So, the sentence becomes: 'The airplane glided past the bird.'
'The little kite ______ higher than the big kite in the sky. (sroade)'
The correct word is 'soared' . So, the sentence becomes: 'The little kite soared higher than the big kite in the sky.'
'Manav ______ the high wall looking for his kite. (cldbiem)'
The correct word is 'climbed' . So, the sentence becomes: 'Manav climbed the high wall looking for his kite.'
'Dry leaves ______ around the garden in the wind. (delwihr)'
The correct word is 'whirled' . So, the sentence becomes: 'Dry leaves whirled around the garden in the wind.'
Now for the list of words to fill in:

Each column features rhyming words, and the missing letter or letters are common for words within a column. For example, all words in the first column miss the letter 'l', and all words in the second and third columns miss 'll' and 'le', respectively.
A current of 15.0 A flowing for 30 seconds results in a total charge of 450 coulombs. This corresponds to approximately 2.81 x 10^21 electrons flowing through the device. Therefore, that is the total number of electrons that flow in the given time.
