It's not the electricity. It's how we produce it.

Solar panels, wind turbines, nuclear reactors, and water wheels can be used to produce electricity with no effect on climate.

Coal, oil, wood, gasoline, natural gas, household trash, and tall dry grass can be burned to boil water to make steam to turn a generator and make electricity. When everybody does that, the burning releases enough Carbon Dioxide into the atmosphere to futz up the Earth's climates. That's exactly what we have done for the past 200 years.

Eva is in a closed, dark room. She uses her arm muscles to turn on a lamp. When she moves her hand closer to the lamp, the light

Well, we know that the total energy in a closed system remains constant.

The problem with the story of Eva is that she is not in a closed system.
If the dark room were really a closed system, then she could press the
button or turn the switch all day, and the lamp could not light. It needs
electrical energy coming in from somewhere in order to turn on.

Let's say that Eva used her arm muscles to strike a match and light the
candle on the table. Then we would have have food energy, muscle
energy, chemical energy in the match, chemical energy in the candle,
heat and light energy coming out of the candle, heat energy soaking into
her hand, light energy bouncing off of the book and into her eyes ... all
going on during the story, and the sum total of all of them would remain
constant.

A motorcycle accelerates uniformly from rest and reaches a linear speed of 24.8 m/s in a time of 9.87 s. The radius of each tire

Vinvika [58]

Answer:

8.756 rad/s²

Explanation:

Given that:

A motorcycle accelerates uniformly from rest, then initial velocity v_i = 0 m/s

It final velocity v_f = 24.8 m/s

time (t) = 9.87 s
