Answer:
Explanation:
Look at the equation for Potential Energy. PE = mass times gravity times the height. Filling in and solving for h:
34.3 = .5(9.8)h so
34.3 = 4.9h so
h = 7 meters

Answer:
Experimental
Explanation:
Here the dependency of pressure on the temperature is to be determined. For finding this factor we need to calculate the pressure of the object at different temperature.
The process of calculating pressure for different temperature is experimental investigation because we need to perform this experiment for finding these value. On the basis of observed values the we can conclude the dependency.
Thus, this investigation is experimental.
