The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 2.0 rev/s in 11.0 s. At th

mojhsa [17]

Answer:

Total angular displacement will be 19.998 radian

Explanation:

It is given that the washer starts from the rest and reach reach the speed of 2 rev/sec in 11 sec

So initial angular velocity $\omega _i=0rad/sec$

And final angular velocity $\omega _f=11rad/sec$

Time t = 11 sec

So angular acceleration $\alpha =\frac{\omega _f-\omega _i}{t}=\frac{2-0}{11}=0.1818rad/sec^2$

So angular displacement in this 11 sec

$\Theta =\omega _it+\frac{1}{2}\alpha t^2=0\times 11+\frac{1}{2}\times 0.1818\times 11^2$

$\Theta =\omega _it+\frac{1}{2}\alpha t^2=0\times 11+\frac{1}{2}\times 0.1818\times 11^2=10.99radian$

Now the washer slows down and stops in 9 sec

So final angular velocity = 0 rad/sec

So angular acceleration $\alpha =\frac{0-2}{9}=-0.222rad/sec^2$

So angular displacement $\Theta =2\times 9-\frac{1}{2}\times 0.222\times 9^2=8.991radian$

So total displacement in 20 sec = $=10.999+8.999=19.998radian$

A wave has a frequency of 450 Hz and a wave length of 00.52 m what is the speed of the wave?

nata0808 [166]

Wave speed is always (frequency) x (wavelength)

Speed = (450 /sec) x (0.52 m)

= 234 m/sec .

Classify the three phases of matter according to their

leva [86]

Answer:

Well, the densities of the condensed phases, solids, and liquids, are more or less constant...

Explanation:

...and not subject to change. The condensed phases are largely incompressible. On the other hand, the density of the gaseous phase is highly variable...and is a state function of temperature, pressure, volume, and amount of gas... And gaseous phases should have an intrinsically low density in comparison to solid and liquid phases...
