Summarize what you read on the three websites you visited by identifying the advantages and disadvantages of using plastics.

nexus9112 [7]

There are both advantages and disadvantages in using plastics:
The advantages are:
Plastic is cheap to manufacture because it is easy to mold. It is light but durable and unbreakable. Plastic does not rust and it is water resistant.
Plastic is reusable over and over again and when it is worn, the cost of replacement is cheaper than glass or rubber. It is odorless and chemical resistant.
The disadvantages of plastic are:
Plastic can cause cancer. Recycling plastic can cause toxic chemicals to be released during the process. It has low heat resistance and melts when placed near fires. Plastic containers for food absorb the smell of the food even when washed thoroughly. Small parts in plastic toys can cause choking in small children, the same with plastic bags when accidentally wrapped around children's heads. Plastics can clog up sewer systems when people through them away indiscriminately.

Which involves more work in the scientific sense: moving the boxes and the furniture down from the second floor or up to the fif

Advocard [28]

Answer:

moving the boxes and the furniture up to the fifth floor.

Explanation:

The work done when moving an object up or down is equal to its change of gravitational potential energy:

$W=mg \Delta h$

where

m is the mass of the object

g is the gravitational acceleration

$\Delta h$ is the change in height of the object

We have two opposite situations:

1) when an object is moved upward, $\Delta h$ is positive, so the work done W is positive as well: this means that we need to do work in order to move the object, because we have to "win" the effect of gravity, which pulls the object downward

2) when an object is moved downward, $\Delta h$ is negative, so the work done W is negative as well: this means that we do not need to do work on the object, because it is already done by gravity, which pulls the object downward.

Therefore, more work is done when we are moving the boxes and the furniture up to the fifth floor.

A runaway railroad car, with mass 30x10^4 kg, coasts across a level track at 2.0 m/s when it collides with a spring loaded bumpe

Natalija [7]

Answer:

0.775 m

Explanation:

As the car collides with the bumper, all the kinetic energy of the car (K) is converted into elastic potential energy of the bumper (U):

$U=K\\frac{1}{2}kx^2 = \frac{1}{2}mv^2$
