Question

Ratio of angular speed of second's hand to how
hand of a standard clock is​

Answer 1

$]\huge\red{\mathfrak{Answer:-}}$

$To \: complete \: one \: second \: the \: arm$

$of \: second \: moves \: 360∘$

$Angular \: \: speed \: is \: \frac{2\pi}{60} </p><p></p><p></p><p></p><p></p><p>$

$Hour \: hand \: completes \: 1 \: rotation</p><p></p><p>12hrs</p><p></p><p>$

$360∘ \: in</p><p></p><p> \: 12hrs</p><p></p><p>$

$Angular speed is \: \frac{2\pi}{12 \times 3600}$

$Therefore \: the \: ratio \: of \: angular \:$

$velocity \: is \: given \: as$

$\frac{2\pi}{60} = \frac{2\pi}{12 \times 3600}$

Hence the ratio of the angular speed of hour and seconds is 1:720.

Answer 2

720:1

EXPLANATION: We know the second hand of the clock taken 60sec (1 min) to cover an angular distance 2π radians (360°). For an hour hand complete one rotation that is 2π radians it take 12 hours (12×3600 second) . Finally the ratio is 21600×30=720:1
