If 9.2 femptosections is equal to 9.2 ×10^-15 seconds what is the exponential equivalent of fempto?
Vladimir79 [104]

Answer:

1 fempto = 10⁻¹⁵

Explanation:

Data Given:

9.2 fempto second = 9.2 ×10 ⁻¹⁵ seconds

exponential equivalent of fempto = ?

Solution:

To find exponential equivalent of fempto

As we know

we look at the given data

That is fempto seconds = 9.2

when we write only seconds then we write 10⁻¹⁵ instead of fempto

that is

9.2 ×10 ⁻¹⁵ seconds

So the exponential equivalent of fempto = 10 ⁻¹⁵

That is -15 exponent to 10

So,

10 ⁻¹⁵ = 0.00000000000001

1 fempto = 10 ⁻¹⁵
