Hen a 0.20-kg block is suspended from a vertically hanging spring, it stretches the spring from its original length of 0.050 m to 0.060 m. the same block is attached to the same spring and placed on a horizontal, frictionless surface. the block is then pulled so that the spring stretches to a total length of 0.10 m. the block is released at time t= 0 and undergoes simple harmonic motion. page 24.what is the maximum acceleration ofthe block?

Answer

mass of the block = 0.2 Kg

it stretches the spring from its original length of 0.050 m to 0.060 m.

total length = 0.1 m

FOR , VERTICAL SYSTEM:

K Δx = mg ,    Δx = 0.01 m

k =196 N/m

f = 4.98 Hz

for horizontal system

k Δ x = ma

a = 49 m/s²

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

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.
