Answer
negative power of 10
Work Step by Step
A bird's heart beats around 600 times per minute.
This is equivalent to about 10 heartbeats per second.
Thus, the time between heartbeats is around one-tenth of a second.
There are 3600 seconds in one hour.
Hence,
$\dfrac{1}{10} \text{ of a second} = \dfrac{\frac{1}{10}}{3600}\text{ of an hour}=\dfrac{1}{36000} \text{ of an hour}$.
Since the measurement is a very small number, then its equivalent scientific notation will involve a negative power of 10.
