3.) The Boeing 747 can carry more than 560 passengers and has a maximum speed of about 9.70 × 102 km/h. After takeoff, the plane takes a certain time to reach its maximum
speed. Suppose the plane has a constant acceleration with a magnitude of 4.8 m/s2 .
What distance does the plane travel between the moment its speed is 50.0 percent of
maximum and the moment its maximum speed is attained?

like poles repel so keep pushing north to north and repels funny to see this

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

there are no contact forces mentioned on the list of choices that you've provided.
