The second hand of a clock completes one full revolution every 60 seconds. To move from the 3 to the 8 on the clock face, the second hand needs to cover a distance of 5 out of the 60 total seconds on the clock. Therefore, it would take 5/60 or 1/12 of a minute for the second hand to move from the 3 to the 8, which is equivalent to 5 seconds.
When the second hand is at 4 on a clock, 20 seconds have passed since the minute hand was pointing directly at the 12.
The second hand of a clock completes a full revolution every 60 seconds, which is equal to 2π radians. Therefore, in 30 seconds, the second hand turns through π radians.
The second hand on the clock circles 420 times in 7 hours.
To determine the number of seconds it takes for the second hand of a clock to move from 12 to 2, we need to understand the motion of the second hand. The second hand completes one full revolution (360 degrees) in 60 seconds. The clock face is divided into 12 equal sections, each representing an hour. Each hour section represents: \frac{360^\circ}{12} = 30^\circ When the second hand moves from 12 to 2, it moves across 2 hour sections. Therefore, the angle swept by the second hand is: 2 \times 30^\circ = 60^\circ Since the second hand completes 360 degrees in 60 seconds, it sweeps through 1 degree in: \frac{60 \text{ seconds}}{360^\circ} = \frac{1}{6} \text{ seconds per degree} Therefore, to sweep through 60 degrees, the second hand will take: 60^\circ \times \frac{1}{6} \text{ seconds per degree} = 10 \text{ seconds} Thus, it takes 10 seconds for the second hand to move from 12 to 2.

A 45-second shot clock was introduced in the NCAA men's game in the 1985-86 season. In the 1993-94 season, the shot clock time was reduced to 35 seconds.
