I think the answer is half a second cause Time period = Time taken by the pendulum/Number of oscillations made by the pendulum so 5 divided by 10 equals 0.5 which is half a second
Answer:
B. Check her building’s foundation to ensure it is resistant to shaking caused by moving tectonic plates
Explanation:
Refractive index(n)= speed of light in vacuum/ speed of light in medium.
Since refractive index is 1.11, and usually we know that the speed of light is 300,000km/s, simply divide 300,000km/s over 1.11. That is, 270,270.2703 when simply rounding, its 270,270 km/s.
