  1. The necessary means to make fossil fuel consumable energy is heat burns the source to make it energy

  • 1  Water, at the top of a waterfall controlled by a dam, has potential energy.
  • 2  As water moves down the waterfall, the water’s potential energy from its earlier position transforms into motion/kinetic energy.
  • 3   The falling water lands on a turbine which spins a generator.
  • 4   As the turbine (generator) turns, it moves copper wire along a magnet which creates a flow of electrons (electricity), which is then transferred to a wire.
  • 5  The electricity travels through wires from the generator in the hydro-station to your house, and the wires continue behind the walls in your home to your electrical outlets.

     Hydro:  Because it would take to much to set up a bunch of turbines even though its renewable, people don't have lakes or river in the city therefore its inefficient there .

     Wind: Its not always windy so when wouldn't always be able to power your electricity.

      Solar power:  Would be very expensive to set up solar powered consumers every where and you  would not have electricity at night when the sun goes down so therefore it would be inefficient.

  •  Question 11) Coal and things like wen use today which is probably a limited source but a reliable one.

  •    Part 2:  Its so dependable because it is able to keep our lights and things on now and there's plenty of it at the time .

12: Yes because if we drained all from ne source it would be out pretty soon.

   13: I'm not sure sorry but here's what I think

Chemical (potential)

Thermal

Motion

Electricity

  14:

  • We need it to power the other wires that gives us light power to things like gas pumps and electronics

  • It helps get water to peoples house with powering pumps

  • It goes all through the city to ensure that we are able to do things like have lights to see at night and so on

                   I HOPE THIS HELPS IT TOOK A WHILE :D

Social security number is an example of a.a numerical variable. b.a categorical variable. c.either a numerical or a categorical
satela [25.4K]

Answer: b.a categorical variable.

Explanation:

In numerical variables, such as rainfall measured in inches or the number of sales in a day, the numbers have a numerical meaning. But a categorical variable is a category such as gender and national origin. It can be represented as a number, like the Social security number, but the numbers won´t have a numerical value. If your SSN is bigger than mine, it doesn´t mean that you are greater or at a different level on a scale, because the numbers are used as categories, not as mathematically meaningful.
