Skate park is a good example that maintains the law of conservation as skater neither creates nor destroys energy.
Explanation:
As per the law of energy conservation, energy cannot be created nor can be destroyed but it’s form can definitely be changed. This theory can be well justified by the example of skate park playground. According to the rules of this law a skater can never go high more than 2 meters on the ramp’s other side because it has that gravitational energy potential.
With every drop of the skater on the ramp the potential energy of the skater changes into kinetic energy. This two sides of the law justifies the fact that skate playground should be designed in such a way that it supports the law of conservation of energy.
<u>Answer:</u>
<em>The measurement 100.5 mL has 4 significant figures.</em>
<u>Explanation:</u>
Significant figures are defined as the digits that provides information in order to maintain accuracy and precision of a measurement. <em>Any nonzero number, trailing zeros with a decimal point and zeros between two numbers are recognizes as significant digits. </em>
Whereas, the figures which do not contribute to sustain the accuracy and precision of the measurement are insignificant figures.
<em>The leading zeros in any digit and the trailing zeros without decimal are considered as insignificant figures. </em>
<em>As in 100.5 1, two zeros and 5 after a decimal is significant figure which are 4 in total.</em>
