Taking shorter showers, turning off the lights when you aren't in a room, use energy efficient lightbulbs like LED's, use the air conditioning only when you really need it, and use the heat less in the winter.
Answer:
Distance = 30 m
Explanation:
Since the position of the bus is at zero, and distance is a scalar quantity. That is, we are only concerned about the magnitude
If Angela ran to the bus and back to where she started, the distance travelled will be:
Distance = 15 + 15 = 30 m
But her displacement will be:
Displacement = 15 - 15 = 0.
It would be hard so many factors play a role in this angle kinetic potential energy gravity positioning height weight etc.to keep something as described moving as long as possible you'd have to build it heavily enough to balance out the momentum at each climax of the swing to balance with the gravitational pull of the earth core.I'd use a material such as copper for the variable.Also the weight distribution on the variables base plays a role.Take all the into account and experiment for a while!maybe one day you could find the right proportions in every role for kinetic potential gravitational momentum and weight to keep it going forever. As said alotta factors play a huge role in this experiment <span />
<span>the speed of something in a given direction. so i think none of these</span>
