According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Also if a car was going straight but another car (unbalanced force) bumps into it causing the motion of the car to change.
Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They<span> haven't been able to find a signal for earthquakes( there is no obvious sign to say that an earthquake is coming very soon).</span> They do have a pretty good idea of where an earthquake is most likely to hit, but they still can't predict exactly when it will happen.
However, the probability of a future earthquake can be calculated, based on scientific data. Scientists estimate that the probability of a major earthquake occurring in the San Francisco Bay area over the next 30 years is 67%.
Collagen is single most abundant body
Food - increase in height
Predators - fast reproduction, fast in general
Heat/lack of water - Cam photosynthesis, storage of water
Predator/prey arms war - sensors along side to detect prey, sense of smell, etc
Answer:
Lightyears
Explanation:
When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.
Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.
This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km
If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.
