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.

A stone is thrown with an initial speed of 11.5 m/s at an angle of 50.0 above the horizontal from the top of a 30.0-m-tall build
rewona [7]

Answer:

The magnitude of the horizontal displacement of the rock is 7.39 m/s.

Explanation:

Given that,

Initial speed = 11.5 m/s

Angle = 50.0

Height = 30.0 m

We need to calculate the horizontal displacement of the rock

Using formula of horizontal component

v_{x}=u\cos\theta

Put the value into the formula

v_{x}=11.5\times\cos50

v_{x}=7.39\ m/s

Hence, The magnitude of the horizontal displacement of the rock is 7.39 m/s.

Two factor that affect gravitational force​
Gnoma [55]
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
