The displacement x of a simple harmonic motion is given by X = 24 cos (6.28t + 1.57) meters. What is the maximum speed of the oscillator.

And for this case we can write this expression like this:

The velocity would be given by the first derivate and we got:

And the maximum velocity would be:

Explanation:

For this case we have the following function for the position:

And for this case we can write this expression like this:

The velocity would be given by the first derivate and we got:

And the maximum velocity would be:

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.
