Part 1. if an object oscillates 100 time in 50 seconds what will be the frequency and periodic time?

part 2. consider a mass oscillating with simple harmonic motion represented by the equation x=2/5cos[2π t + π ] meters . calculate the amplitude, displacement, speed and acceleration if it completes the motion at a time of 0.7 seconds

the answer would be   dignified - apex

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
