I think its true because they are a soft solid that can be broken down into a liquid... Hope this helps in any way :3
Auroras are frequently seen : B. After solar flares
The Aurora is created by an ongoing influx of particles into the Earth's existing magnetic field,
This particles originated from the Sun as part of Solar wind
hope this helps
Answer:
466.956 J
Explanation:
potential energy = mass x gravitational field(9.81) x height
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!
Angular acceleration = (change in angular speed) / (time for the change)
Change in angular speed = (ending speed) minus (starting speed)
Change in angular speed = (16 rad/s) - (zero) = 16 rad/s .
Angular acceleration = (16 rad/s) / (0.4 s)
(Average) angular acceleration = 40 rad/s²
