How many seconds will it takes for the second hand o a clock to move from 12 to 2?
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.
What else can I help you with?
Why is the second hand on a clock called a second hand?
Because it counts seconds.
What is the rotational speed of the second hand on a clock that measures the seconds?
It takes 1 minute to rotate 1 time.
Why is the third hand on the clock called a second hand?
Because it points at the seconds? hours minutes seconds
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.
What is the least count of a clock if it has hours hand minutes hand and seconds hand?
one 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.
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 have passed when the second hand is at 4?
When the second hand is at 4 on a clock, 20 seconds have passed since the minute hand was pointing directly at the 12.
How many radians does the second hand of a clock turn through in thirty second?
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.
If one minute takes the second hand a 36o degree clock wise, then how many degrees clock wise would take the second hand to complete 1 second?
1 per minute.
