A3.49 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 111 n/m. the block is shoved parallel to the spring axis and is given an initial speed of 10.3 m/s, while the spring is initially unstrained. what is the amplitude of the resulting simple harmonic motion?

18.2 cm

Explanation:

The kinetic energy of the block

= .5 x 3.49 x 10⁻² x 10.3²

= 1.85 J

If x be the compression created in the spring due to this kinetic energy

1.85 = 1/2 k x²

= .5 x 111 x²

x² = 3.3 x 10⁻²

x = 0.182 m .

= 18.2 cm

This will be the amplitude of oscillation under SHM.

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.
