The force F⃗ pulling the string is constant; therefore the magnitude of the angular acceleration α of the wheel is constant for
abruzzese [7]

Answer:

The answer is "\boxed{\boxed{\omega = \sqrt{\frac{2fd}{kmr^2}}}}"

Explanation:

\to d= r \theta \\\\ \to \theta =\frac{d}{r}\\\\\to \omega^{r} - \omega_{0}^{r} = 2 \alpha \theta\\\\\to \omega^{r} = 2 \alpha \theta    - \omega_{0}^{r} \\\\\to \omega^{r} = 2  (\frac{F}{Kmr}) \frac{d}{r}\\\\\to \omega = \sqrt{\frac{2fd}{kmr^2}}

A person measures his or her heart rate by counting the number of beats in 30s. If 40±1 beats are counted in 30.0±0.5s, what is
nordsb [41]

Answer:

Rate = 1.33 \pm 0.055 beats per second

Explanation:

Number of heart beats = 40 \pm 1

time taken = 30.0 \pm 0.5 s

now we have

N = 40 \pm 2.5%

t = 30.0 \pm 1.67%

now rate of heart beat is defined as number of heart beat per unit of time

so we have

Rate = \frac{N}{t}

Rate = \frac{40 \pm 2.5}{30 \pm 1.67}

so we have

Rate = 1.33 \pm (2.5 + 1.67 )

Rate = 1.33 \pm 4.17%

Rate = 1.33 \pm 0.055 beats per second
