Answer:
The energy conversion when a solar cell is used to light a street lamp is Option B: solar energy - electric energy - light and heat energy
Explanation:
From the 'Law of conservation' of energy, energy cannot be 'created' nor it can be destroyed. But we can convert energy from 'one form' to 'other'. The devices that transform energy from one form to another are called transducers.
'Solar cells' also known as the photo voltaic cells. These devices transform light energy into electrical energy directly. When these solar cells are used in a street lamp, it will convert this electrical energy into heat and light energy.
An apostrophe used as a contraction replaces a letter such as 'can't' the apostrophe replaces the 'o' in 'not' another common example would be 'it's' as in 'it is'. The apostrophe replaces the 'i' in 'is'.
To show possession take the noun and add an apostrophe and an 's' such as 'Mrs. Noble's friend' The apostrophe and the 's' show possession. If the noun is plural or already ends in an 's' do not put an 's' again. For example 'the birds' tree is lovely' Birds as in many birds if it was one bird it would be 'the bird's tree is lovely'
Hope this helps! good luck :)
