What Is the "Electroweak" Force

question 118

Multiple Choice

What is the "electroweak" force?

• A) This is a fifth force, distinct from the original four, which helps to explain dark energy.
• B) When charged particles of both signs (positive and negative) are closely mixed, the electromagnetic force-generally infinite in extent-is limited in its practical range. Under these circumstances, it is termed electroweak.
• C) At sufficiently high temperatures the electromagnetic force and the weak nuclear force are indistinguishable. This composite force is called electroweak.
• D) At sufficiently high temperature the strong nuclear force and gravitational force disappear. At even higher temperatures the weak nuclear force and the electromagnetic force combine to form the electroweak force. It is the only force that exists at this temperature.
