Answer: First stage
Explanation:
The four stages of technological design include:
• identifying a problem.
• Designing a solution.
• Implement, build, and test the design.
• Determine if solution met the need.
In this scenario, Robert Shuman identified the problem. This was depicted as he stated that coal and oil would eventually run out and that humans needed to learn how to use the more-abundant energy resource of the Sun,
The situation given above is that of the geometric sequence with first term equal to 75 meters and the common ratio equal to 0.40. The sum of the terms for an infinite geometric sequence is expressed in the equation,
S = a1/(1 - r)
Substituting,
S = (75 m) / (1 - 0.4) = 125 m
Therefore, the total distance that the pendulum had swung before finally coming to rest is 125 m.
Answer: C. A rubber eraser
It would be A because Light energy can't be used to make a Nuclear Weapon.
Electricity turns on a light bulb so B is scientifically correct.
If potential energy can be turned to Kinetic, it can also be switched. so C is scientifically correct
Ever heard of Geothermal power plants? So D is scientifically correct.
Meanwhile, A is impossible. so it is the answer you want to choose. Because the question asked for the one which is impossible.
