2) ben stands on a bathroom scale, whose force(spring) constant is 220 kn/m. how far is the spring
scale compressed if ben has a mass of 180kg?

8.0 mm

Explanation:

Force of a spring is:

F = kx

where k is the spring constant and x is the displacement.

When the force is equal to Ben's weight:

mg = kx

(180 kg) (9.8 m/s²) = (220,000 N/m) x

x = 0.0080 m

The spring compresses 0.0080 m, or 8.0 mm.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
