Claudia and her team of scientists develop a new car battery that recharges electric cars at a fast rate. How will this new technology most likely influence society?

People will rely even more on gasoline.
The availability of fossil fuels will increase.
Greenhouse gas emissions will remain above normal.
Waste operators will handle less hazardous material.

Waste Operators will handle less hazardous material.

Explanation: Since the electric car is electric it produces hazardous material and now that it doesn't it wont.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
