The color aftereffects phenomenon predicts that, after staring at a bright red rectangle for a period of time, you will see a __

___ when you look away at a white background.

Answer:

The answer for this is Green Rectangle.

Explanation:

The hue after effects theory suggests that as you glance away at a white background, you can see a <em>Green Rectangle</em> after looking at a bright red rectangle for a period of time.

All this is an after-image consequence. Afterimage is a form of optical illusion in which, even after exposure to the original image has ended, an picture appears to appear momentarily.

A person pulls a bucket of water up from a well with a rope. Assume the initial and final speeds of the bucket are zero (Vi-Vf-0
n200080 [17]

Answer:

a

This a closed system because the mass of the system is conserved

The energy system that undergoes change is the Potential energy system

The energy system diagram is shown on the first uploaded image

b

Work done = Change in gravitational potential energy

So solving algebraically for work done would be

    Work done   = m*g*h

where m is mass

          g is acceleration due to gravity

          and h is the height

c

Work done in terms of force and distance is = mg

where  m is mass of bucket and

            g is acceleration due to gravity  

Explanation:

a) At the start, potential and kinetic energy were zero. so, energy is zero.

As the person pulls the bucket up, the potential energy becomes mgh.

so,final energy will be consisting of only potential energy.

B) Here work done is equal to change in gravitational potential energy.

W = \Delta P.E

W = m*g*h

where g = 9.9 m/s^2

C) Work = force * distance

mgh = force * h

force = mg

force = weight of bucket
