Answer:

Explanation:
As we know that the speed of the rocket is v1 and v2 at the bottom and top of the window
then we will have



also we know that


now we have

also we have

now if the sill of the window is at height 8 m from the ground then we have



Acceleration = change in velocity/time
= 40/5
=8m/s^2
Answer:
because they dont know how big it willactually be? idk
or so deep dish can fit too
The physical model of the sun's interior has been confirmed by observations of neutrino and seismic vibrations.
<u>Explanation:</u>
Sun's interior is composed of very high temperature and solar flares. So it is very difficult to understand the interior of the sun. But by using the vibrations of neutrino and seismic waves emitted by the solar waves, the physical model can be assumed.
As the interior of the sun performs continuous chain of hydrogen cycle. So the continuous emission of energy from the chain reaction releases neutrino. So these vibrations in neutrino and seismic vibrations, the physical model can be assumed easily.
