How many seconds does it take the second hand of a clock to move from 3 to 8?
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.
What is the speed of a clock hand?
The speed of a clock hand depends on what the clock hand indicates the second hand is 2pi per 60seconds, the minute hand is 2pi per 3600 seconds and the hour hand is 2pi per 216000 seconds.
If a clock was exactly on time at noon on Monday At 8pm on Tuesday it was 32 seconds slow at the same rate how much did it lose in half an hour?
The clock lost 32 seconds in 32 hours ie 1 second per hour. So in half an hour it would have lost half a second.
If a clock chimes five times in four seconds how many times will it chime in ten seconds?
12 Chimes.Assuming that a "chime" is the full sound range from start to finish, the clock will chime 10x in 8 seconds. It will chime 2.5x in 2 seconds, and assuming that a chime is the full sound length from start to finish, .5 chime does not equal 1 chime.Therefore 10+2=12 ChimesThe above answer is only right if we assume that at 0 seconds the clock chimes 0 times.If we instead assume a starting signal - meaning the clock chimes for the first time at 0 seconds - then it would be reasonable that each consecutive chime would happen one second later. Therefore after 10 seconds the clock would have chimed 11 times.One starting signal and 10 second chimes.
How long does it take for the second hand of a watch to move 1 micron?
The second hand makes one full revolution in 60 seconds. The distance travelled by the tip depends on the length of the second hand - this is the radius of the circle. For example, for a 10-centimeter second-hand (the clock has a diameter of about 20 centimeters - that's a clock like you would typically see on a wall), the speed of the second-hand's tip is (2 x pi x radius) / 60 seconds = 2 x 3.14 x 10 / 60 or about 1.05 cm/second.
What is the second hand on a clock called?
The second hand on a clock is called the "second hand" because it measures seconds as they pass, helping to indicate the precise time.
What measures minutes and seconds?
clock, stopwatch, watch
What unit does a clock measure in?
Qa in Babylon. Qa = the volume of the water flowing from and into the water clock.
Why is the third hand on the clock called a second hand?
Because it points at the seconds? hours minutes seconds
Why is the second hand on a clock called a second hand?
Because it counts seconds.
Timers at a track meet used four different clocks to time an event. Which recorded time is the most precise?
The most precise recorded time is the one with the smallest unit of measurement. If one clock measures in milliseconds (1/1000 of a second), it would be more precise than a clock that measures in tenths of a second (1/10 of a second) or seconds.
What unit does a clock use?
A clock measures and displays units of time, such as seconds, minutes, hours, and - on some clocks - days, months, and years.
How many seconds does it take the second hand of a clock to move from 3 to 8?
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.
Does a clock have rotational symmetry?
Yes
Can second be measured by clock?
In many cases, there is a third hand that ticks on seconds
How do tell time in seconds?
look at the nearest clock with a second hand is the easiest way
How many seconds on college basketball shot clock?
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.
