Answer:
D. Synthetic polymers are inexpensive to produce.
Explanation:
Hailey should include that synthetic polymers are inexpensive to produce as a benefit of synthetic polymers.
Synthetic polymers are artificially produced. These polymers come about from petroleum oil. Their hydrocarbons are industrially worked to produce the long chain hydrocarbons to form polymers.
Most of these polymers are very cheap to produce and does not cost too much. This is why they almost found everywhere.
Explanation:
Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. <span>As is implied by the equation for </span>power<span>, a unit of </span>power <span>is equivalent to a unit of work divided by a unit of time. The formula would be as follows:
P = W/t
We calculate as follows:
500 W = 15000 J / t
t = 30 s</span>
Fusion,melting,vaporization,submlimination are examples of endothermic changes
The Generator transforms the mechanical energy of the turbine into electrical energy.
