A spring was at its resting position where it is attached to a wall at its left side and a block at its right side as shown belo
gladu [14]

Answer:

The force of spring will be "3.75 N". The further explanation is given below.

Explanation:

The given values are:

Spring constant, K = 75.0 N/m

x₁ = 0.200 m

x₂ = 0.150 m

So that,

⇒ x=x_{1}-x_{2}

⇒    =0.200-0.15

⇒    =0.05 \ m

Now,

Force of spring will be:

⇒  F=K\times x

On putting the estimated values, we get

⇒      =75\times 0.05

⇒      =3.75 \ N

Which best explains how the body maintains homeostasis?
kolezko [41]

McBossatronio,

The answer is the first option "all systems work together to stabilize the body." Homeostasis is the internal conditions that all living things have basically meaning how the body keeps cool during hot weather, or warm during cold weather.  You ever wonder why you sweat when it's hot, or shiver when it's cold that's your body keeping warm and cool which helps all your systems work together.

Hope this helps!
