Make a list of 3 major components in your computer. for each component identify the specific material used (search the internet for this). explain, in only one or two sentences each, why you think that material is chosen.

a. Polyvinyl Chloride.

b. Lead.

c. Chromium

Explanation:

Hello, here the explanations:

a. Polyvinyl chloride is a plastic which helps to build the shell of the monitors, keyboards and mouses because it is resistant, long-termed and electricity isolating.

b. Lead helps to connect the computer chips to the printed circuit boards since it is a pretty god electrical conductor.

c. Chromium is a metal used in plating applications such as coverages to either prevent corrosion or conduct the electricity.

Best regards!

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
