A string is wrapped around a uniform disk of mass M = 1.2 kg and radius R = 0.07 m. (Recall that the moment of inertia of a unif
pentagon [3]

Explanation:

Given that,

Mass of disk = 1.2 kg

Radius = 0.07 m

Radius of rod = 0.11 m

Mass of small disk = 0.5 kg

Force = 29 N

Time t = 0.022 s

\theta=0.023\ m

Distance d= 0.039 m

(I). We need to calculate the speed of the apparatus

Using work energy theorem

W=\Delta K.E

Fd=\dfrac{1}{2}mv^2

v=\sqrt{\dfrac{2Fd}{M+4m}}

Where, m = total mass

v = velocity

F = force

d = distance

Put the value into the formula

v=\sqrt{\dfrac{2\times29\times0.039}{1.2+4\times0.5}}

v=0.840\ m/s

(b). We need to calculate the angular speed of the apparatus

Using formula of torque

\tau=I\alpha

F\times=(\dfrac{1}{2}MR^2+4mb^2)\alpha

29\times0.07=(\dfrac{1}{2}\times1.2\times0.07^2+4\times0.5\times0.11^2)\alpha

\alpha=\dfrac{29\times0.07}{0.02714}

\alpha=74.79\ rad/s^2

We need to calculate the angular speed of the apparatus

Using equation of angular motion

\omega=\omega_{0}+\alpha t

Put the value into the formula

\omega=0+74.79\times0.022

\omega=1.645\ rad/s

(c).  We need to calculate the angular speed of the apparatus

Using equation of angular motion

\omega_{0}^2=\omega^2+2\alpha t

Put the value into the formula

\omega_{0}^2=1.645^2+2\times74.79\times0.022

\omega=2.44\ rad/s

Hence, This is required equation.

7. Describe about the difficultites that would arise due to lack of non-uniformity in measurement. ​
r-ruslan [8.4K]

Answer:

Many difficulties would arise if there was a lack of uniformity in the measurement of various weights and measures between business, industry, individuals and countries. The biggest implications for a lack of uniformity are in health and safety, equity and sustainability.
