input with options: Answer the following question given this paragraph: Radioactivity was discovered in 1896 by a French physicist named Antoine Henri Becquerel. Becquerel was experimenting with uranium, which glows after being exposed to sunlight. Becquerel wanted to see if the glow was caused by rays of energy, like rays of light and X-rays. He placed a bit of uranium on a photographic plate. The plate was similar to film that's used today to take X-rays. You can see an example of an X-ray in Figure below . As Becquerel predicted, the uranium left an image on the photographic plate. This meant that uranium gives off rays after being exposed to sunlight. Q: Name the physicist who discovered radioactivity? A:
OPTIONS:
- louis pasteur
- neal degrasse tyson
- albert einstein
- antoine henri becquerel
output: antoine henri becquerel

Answer the following question given this paragraph: Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage. Q: What type of generators use electromagnetic induction to change kinetic energy to electrical energy? A:

OPTIONS:
- conductors
- radiators
- thermal generators
- electric generators

Answer: electric generators

Problem: OPTIONS:
- electrical
- free
- active
- kinetic
Q: Answer the following question given this paragraph: Helicopter pilots are quite familiar with rotational kinetic energy. They know, for example, that a point of no return will be reached if they allow their blades to slow below a critical angular velocity during flight. The blades lose lift, and it is impossible to immediately get the blades spinning fast enough to regain it. Rotational kinetic energy must be supplied to the blades to get them to rotate faster, and enough energy cannot be supplied in time to avoid a crash. Because of weight limitations, helicopter engines are too small to supply both the energy needed for lift and to replenish the rotational kinetic energy of the blades once they have slowed down. The rotational kinetic energy is put into them before takeoff and must not be allowed to drop below this crucial level. One possible way to avoid a crash is to use the gravitational potential energy of the helicopter to replenish the rotational kinetic energy of the blades by losing altitude and aligning the blades so that the helicopter is spun up in the descent. Of course, if the helicopter's altitude is too low, then there is insufficient time for the blade to regain lift before reaching the ground. Problem-Solving Strategy for Rotational Energy 1. Determine that energy or work is involved in the rotation. Determine the system of interest. A sketch usually helps. Analyze the situation to determine the types of work and energy involved. For closed systems, mechanical energy is conserved. That is,. Q: Helicopter pilots can recover from piloting errors by decreasing altitude, turning some of their potential energy into what kind of energy? A:
Answer: kinetic
