The power source its getting usually determines its voltage.
Answer:
Explanation:
There are two hypotheses she could test:
A cat's heart rate changes while it is napping.

The energy transferred to the spring is given by:

where
k is the spring constant
x is the elongation of the spring with respect its initial length
Let's convert the data into the SI units:


so now we can use these data inside the equation ,to find the energy transferred to the spring:
To find <em>Speed </em>you divide distance by time.
Reasoning:
Displacement is the change in an object's position from the origin.
To find Acceleration you use the equation a=v^2/r
To find Velocity you divide the distance by the time it takes to travel that distance, then you add your direction to it.
<em>To find speed you use distance is over time</em>
