Answer:
The answer is 6.4 ×
Joules
Explanation:
This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:
Force = 8.0 pN = 8.0 ×
N
displacement = 8.0 nm = 8.0 ×
N
Now let us calculate the work.
work = Force × Displacement
work = 8.0 ×
× 8.0 ×
= 64 × 
= 6.4 ×
Joules (in standard form)
