Can u show the problem ?
Acceleration= the rate and change of an object also cars go fast so I think it would be positive acceleration
Hope I helped
I'm not exactly sure but I'm thinking that it's the last one. Sorry if I'm wrong
Answer:
Examples of man-made objects that spread an impulse over a large amount of time are "airbags" in vehicles and "arrestor beds" (for trucks).
Explanation:
The question above is highly related to the topic about "Impulse" in Physics.
"Impulse"<em> refers to an object's change in momentum (the amount of motion in an object) when a force acts upon it for an interval time.</em> When it comes to providing safety to people when it comes to vehicular crashes, impulse plays a vital role.
Let's take the example of airbags in vehicles. Once a vehicle collides with another object, the driver is carried by a forward motion. Without airbags, the time is normally shorter for the driver to be stopped by the windshield. This results to a greater force. However, with the presence of air-bags, the driver will hit the airbag, instead of the windshield. <u>This will lengthen the time of the impact, thus reducing the force.</u>
Another example are the arrestor beds for trucks. Arrestor beds have been designed in order for trucks to stop, since it's hard to maneuver them. <u>With the help of arrestor beds, trucks are able to come to a stop with a longer time interval, but decreased force.</u>
one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth
Explanation:
- The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
- A theory is usually drawn from careful observation of scientific investigation.
- Theories generally provides explanation into a phenomenon that occurs in nature.
- They are products of careful scientific observations and experiments.
- The theory of evolution is but one of them.
