1.5 inches.
In countries outside of the US, 45s often have a smaller album-sized holes (e.g. Australia and New Zealand), or otherwise a pseudo-spider is "built-in" to the record, which can be punched out.

The speed of a ceiling fan is typically measured in revolutions per minute (RPM). A typical ceiling fan may have speeds ranging from around 50 to 200 RPM on the low setting, and up to 200 to 300 RPM on the high setting.
If you are talking about 45 rpm records, 'singles', the plastic insert was called an adapter, or a spindle adapter. They allowed you to play 45's without the awkward 45 spindle you would otherwise have to insert.
Diametric ring magnets typically produce more rotation and torque compared to radial ring magnets. This is because the magnetic field lines of diametrically magnetized rings pass through the center of the ring, providing a more direct and efficient coupling with the rotating element.
After any whole number of revolutions, the total displacement is zeroand so the average velocity is zero.At any instant, the magnitude (speed component) of instantaneous velocity is(pi) x (distance from center of rotation) x (RPM / 30) units per second.
The mean rotational speed of a ceiling fan is typically measured in revolutions per minute (RPM). The average RPM of a ceiling fan can vary depending on the specific model, but it is commonly around 150-250 RPM for normal operation.
The item you put in the middle of a 45 RPM record is called a "center adapter" or "spindle adapter." This small plastic or metal piece fits into the larger hole of the record, allowing it to be played on a standard turntable spindle designed for 33 RPM records. It ensures that the 45 RPM record can properly align and rotate while playing.
The 45 RPM record was developed by RCA Victor in 1949 as a competing format for the 33 1/3 RPM (33) format of rival Columbia records that premiered in 1948. Eventually the 45 RPM format (7 inches in diameter with a one-inch center hole) was adopted for shorter recordings while 33 RPM (12 inches in diameter with a 1/4 inch center hole) was used for so called LP (long playing) albums. This eliminated the need to reduce the groove width or quality of 45 RPM recordings.

A 45 rpm record typically weighs around 7-9 ounces.
No; it was an album track only.
No; it was only ever an album track.
I've seen it called a 45 RPM Adapter.
Yes-it is likely a 78 rpm lp.
The 45 rpm record was followed by the , which in turn was followed by the eight-track tape player.
1894, even though the first records varied in rpm (from about 60-100).
Walt Disney Records
Around 6500 RPM's.
