Question

in the process of vision, the light - sensitive pigment rhodopsin undergoes cis - trans isomerism in response to light in about 2×10^(-10) ms. how many seconds is this? write the answer in scientific notation. when reporting you answer, use the multiplication symbol, ×, not the letter x. provide your answer below:

Explanation:

Step1: Recall the conversion factor

1 ms = 10⁻³ s

Step2: Convert milliseconds to seconds

We have 2×10⁻¹⁰ ms. Multiply by the conversion factor: (2×10⁻¹⁰)×(10⁻³) s.
Using the rule of exponents aᵐ×aⁿ=aᵐ⁺ⁿ, we get 2×10⁻¹⁰⁻³ s = 2×10⁻¹³ s.

Answer:

2×10⁻¹³ s
