How do use the words nuclear energy in a sentence?
there was nuclear energy in the science experiment
Why must neutrons in a chain reaction be controlled?
Neutrons in a nuclear fission chain reaction must be controlled for two reasons... First, they must be moderated, or "slowed down", to exactly the right level of energy required to sustain the reaction. This is because, initially, the neutrons are too fast to sustain the fission reaction. They must be slowed down, but not too much, otherwise the reaction will stop. Second, they must be controlled. You want the reaction to proceed at an orderly pace, at a constant rate. To do this, you need, on a statistical average, exactly one neutron to go on to fission one atom to produce one parcel of binding energy release and one neutron, to repeat without multiplying or dividing. This is what we call KEffective = 1, where the rate of reaction does not change. Moderation and control. In tight balance. Easily upset. Fortunately, when upset, the tendency is to shutdown. That is engineering safety.
What kinetic energy must the electrons have in order to exhibit a specific behavior?
The electrons must have enough kinetic energy to overcome the potential energy barrier in order to exhibit the specific behavior.
In order for energy to be conserved what must happen?
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.
In raising an object, must there be an increase in which type of energy that the object possesses?
Yes, in raising an object, there must be an increase in potential energy that the object possesses.
What is a braking resistor?
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.
Is nuclear energy good for humans and the environment?
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
Can oil burn in a controlled manner to produce heat and energy?
Yes, oil can burn in a controlled manner to produce heat and energy.
In an experiment what are controlled variables?
Controlled variables are quantities that must remain constant.
How is solar energy controlled or processed?
no

Is zofran a controlled substance?
No it is not, but you must have a prescription for it.
Define thyristor controlled braking resistor?
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. See links.
How energy is controlled by biogas?
It isn't. Fuels such as biogas store energy, they don't control it.
Why must a controlled experiment have one manipulated variable?
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
