Q: I know that the answer to the question "What worked together for magnetism to be created?" is in "In 1827, Hungarian physicist Anyos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.". Can you tell me what it is?
A: stationary and revolving components

Q: I know that the answer to the question "Which of the following is affected by the time the landing takes: flight phase, the shape of the area, or ground reaction force?" is in "A higher flight phase results in a higher vertical ground reaction force. Vertical ground reaction force represents external force which the gymnasts have to overcome with their muscle force and has an impact on the gymnasts linear and angular momentum. Another important variable that affects linear and angular momentum is time the landing takes Gymnasts can alter the shape of the area by increasing the time taken to perform the landing. Gymnasts can achieve this by increasing hip, knee and ankle amplitude. With the increase of height, the amplitude in ankles knees and hips rise the bars.". Can you tell me what it is?
A: shape of the area

Q: I know that the answer to the question "Schooling in what locale is not the same as other locales in the UK?" is in "Education in Northern Ireland differs slightly from systems used elsewhere in the United Kingdom, but it is more similar to that used in England and Wales than it is to Scotland.". Can you tell me what it is?
A: Northern Ireland

Q: I know that the answer to the question "How does the calendar work?" is in "The Gregorian calendar is a solar calendar. A regular Gregorian year consists of 365 days, but as in the Julian calendar, in a leap year, a leap day is added to February. In the Julian calendar a leap year occurs every 4 years, but the Gregorian calendar omits 3 leap days every 400 years. In the Julian calendar, this leap day was inserted by doubling 24 February, and the Gregorian reform did not change the date of the leap day. In the modern period, it has become customary to number the days from the beginning of the month, and February 29th is often considered as the leap day. Some churches, notably the Roman Catholic Church, delay February festivals after the 23rd by one day in leap years.". Can you tell me what it is?
A:
The Gregorian calendar is a solar calendar
