You heat your home with electricity generated by a coal-fired power plant. Because energy from the coal is lost in the productio

n and distribution of the electricity, it would be more efficient to just burn the coal in your home (although certainly less convenient!). How much less coal would you need to burn if you heated your home directly with coal, instead of using electricity generated from coal? You would need about

Well since you can only heat your home/water with it and your home stove is less efficient than say the zero-emmisions one in gillete WY. and the distribution cost placed on top of that. you would pay more than the coal-made-electricity. plus you would burn more for the same effect. and coal decomposes in oxygen so that's not EPA condoned anymore. so the answer is. . . none. its more advantageous to just use the electricity

jeyben [28]

Answer:

the car would arrive after 10 hr to Austin.

Explanation:

bus average from amarllo to austin = 60 miles per hour

time takne by bus to reach austin = 8 hr

automobile average from amarllo to austin = 60 miles per hour

from the information given in the question:

60 mph ---    8 h

48 mph ---  x h

By using The inverse variation:

60 : 48 = x : 8

60* 8 = 48* x

480 = 48*x

x = 480/48

x = 10 h

the car would arrive after 10 hr to Austin.

A ball thrown in to the air starts out with an initial upward velocity but eventually slows and stops before falling back to the
Mashutka [201]

Answer:

b) The downward force of gravity

Explanation:

The gravity force has the biggest influence on the deceleration of the ball because no matter how much force you applied on the ball, it will eventually go down again, according to newton's second law:

\sum F=m.a

right after you throw the ball, only the force exerted by the gravity will affect the ball (neglecting air resistance):

m.g=m.a\\a=g

so the object will eventually be going down again.
