A frame of reference can be thought of as the state of motion of the observer of some event. For example, if you're sitting on a lawn chair watching a train travel past you ... you could even watch a glass of water sitting on a table inside the train move ... This seems like a simple and obvious example, yet when you take a step
Answer:
The law of conservation of mass is observed in a balanced chemical equation, which is a chemical equation that shows all mass is conserved throughout the reaction. In a balanced chemical equation, the number and kinds of atoms on each side of the equation should be equal.
in this phenomenon it is denoted by
mass of Liquid 1 + mass of solid = mass of Liquid 2 + mass of gas mass of Liquid
Explanation:
Answer:
Natural frequencies of oscillation and typical earthquake frequencies should be different.
Damping on the structure should be large.
Explanation:
The natural frequency of the structure must be different from the typical earthquake frequency, the more different the better. This is because if both frequencies were the same or similar there is a risk that the building will <u>resonate </u>and collapse.
As for the damping, it must have a high value. This so that the building resists earthquakes better and prevents it from moving dangerously, thus damping on the structure should be large.
Answer:
Explanation:
Because as time passes, new experiments are being conducted with more powerful, advanced technology. This allows scientists to find new data which either causes scientific theories to change, reinforce pre-existing theories, or create new ones.
