Light Nuclei Can Be Split

question 119

Multiple Choice

Light nuclei can be split.For example,a deuteron,which is a proton-neutron combination,can split into a separate proton and separate neutron.Does such a process yield energy or cost energy? Why?

• A)Yields energy.Splitting nuclei of any sort is a basic example of a nuclear reaction releasing massive amounts of energy.
• B)Neither.The amount of energy required to split the light nuclei is exactly the same as that released.This is the basis of the Law of Conservation of Energy.
• C)Costs energy.This fact is consistent with the sum of the masses of the separated proton and neutron being greater than the mass of the original deuteron.
• D)Yields energy.This fact is consistent with the sum of the masses of the separated proton and neutron being less than the mass of the original deuteron.

Central Nervous System

The part of the nervous system consisting of the brain and spinal cord, which interprets sensory information and issues instructions based on past experience and current conditions.

Peripheral Nervous System

The peripheral nervous system is the part of the nervous system that consists of the nerves and ganglia outside of the brain and spinal cord, which connect the central nervous system to limbs and organs.

Afferent Nerves

Nerves that carry sensory information from the sensory receptors towards the central nervous system.

Efferent Nerves

Nerves that carry signals away from the central nervous system to effectors such as muscles or glands, facilitating action and response.
