Coal and other fossil fuels are considered to be "nonrenewable" sources of energy. How does the use of nonrenewable fuels affect the total energy of the universe? A. Nonrenewable energy sources reduce the total energy by using up thermal or kinetic energy. B. Nonrenewable sources of energy add to the total energy of the universe as they are used. C. The burning of fossil fuels permanently reduces the total energy of the universe by using up chemical energy. D. Although the total energy remains constant, nonrenewable fuels convert chemical energy into forms that are difficult or impossible to use again.

the one with the highest speed

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
