Answer: Within any frame of reference that is accelerating
Special relativity was proposed on 1905 by Einstein, who developed his theory based on the following two postulates:
1. <em>The laws of physics are the same in all inertial systems. There is no preferential system.
</em>
2. <em>The speed of light in vacuum has the same value for all inertial systems.
</em>
Focusing on the first postulate, it can be affirmed that <u>any measurement on a body is made with reference to the system in which it is being measured</u>.
Now, taking into account that an inertial reference system is the one that complies with the principle of inertia:
<em>"For a body to have acceleration, an external force must act on it."</em>
The correct answer is
Within any frame of reference that is accelerating
there are different types of power so ill show you all the examples of power.
Answer:
C) about 1/10 as great.
Explanation:
We use the relation between Impulse, I, and momentum, p:
the final speed is zero
We can see that the average Force is inversely proportional to the time, so if the time is 10 times bigger, the average Force is 1/10 as great
