The rocket should be fired for <u>129600 seconds.</u>
Why?
We can calculate for how long should the rocket be fired by using the following equation:
From the statement we know:
- Initial speed equal to zero.
- Force equal to 272N.
- Final speed (for the moment) equal to 62 m/s.
- Mass equal to 72000 Kg.
So, substituting and calculating, we have:
Hence, we have:
Variables: Time
Equations:
Answers: The rocket should be fired for 129600 seconds.
Have a nice day!
Answer:
Left to right and top to bottom
Explanation:
On the periodic table, the properties repeat from left to right and from top to bottom.
Periodic properties have a pattern from the top to the bottom or down a group or family.
Also, across the period from left to right, they also show a repeating pattern.
- Certain properties increase from left to right and decreases from top to bottom. E.g. electronegativity.
- Also, some properties decreases from left to right and increases from top to bottom e.g. atomic radius.
Fusion occurs in the Sun's core, releasing energy that is transferred outward. Once in the radiative zone, gamma rays are transferred by radiation. They are converted to other types of photons, which move into the convective zone, where they are transferred by convection. Finally, energy is emitted from the photosphere.
