Because you are not supposed to be doing this in class Kayleigh! (:
there was nuclear energy in the science experiment
Neutrons in a chain reaction must be controlled to prevent the reaction from reaching a critical mass and becoming uncontrollable. By controlling the rate of neutron production and absorption, engineers can manage the reaction to ensure it remains stable and does not lead to a runaway nuclear event.
The electrons must have enough kinetic energy to overcome the potential energy barrier in order to exhibit the specific behavior.
For energy to be conserved, it must neither be created nor destroyed but only transferred or converted from one form to another. This principle is known as the Law of Conservation of Energy. Energy can change from potential to kinetic, thermal, or other forms, but the total amount of energy must remain constant in a closed system.
Yes, in raising an object, there must be an increase in potential energy that the object possesses.
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. Read more at the link provided below.

with a thermostat
Controlled variables are quantities that must remain constant.
Yes, oil can burn in a controlled manner to produce heat and energy.
Nuclear energy provides electricity which is good for humans, and for the environment it does not produce greenhouse gases, so that is good. However it has dangers too, so must be well controlled

No it is not, but you must have a prescription for it.
It isn't. Fuels such as biogas store energy, they don't control it.
A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. A thyristor (also known as a silicon-controlled rectifier or SCR) is a diode which has a gate terminal on it. Current at the gate allows the thyristor to go into a conducting mode, allowing current to pass. Modern drives will detect when their DC bus voltage reaches a certain threshold (from the energy being returned from the motor during braking) and begin triggering the thyristor periodically (typically PWM, pulse-width modulation) to disperse this energy as heat.

a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
