PERIOD OF THE LEG The period of the leg can be approximated by treating the leg as a physical pendulum, with a period of Equatio

Lesechka [4]

Answer:

Explanation:

We can see from the question that

$T 2\pi\sqrt{\frac{I}{mgh} }$

and $I = \frac{ml^2}{3}$

$m = 16$ % of $67kg$

=> $m =10kg$

from the question $l =48$ % of $1.83m$

Substituting this into the equation

$I = \frac{10.72 * (0.8784)^2}{3}$

=> $I = 2.7571 \ kg m^2$

$h = 0.5 * L$

$h = 0.5 * 0.8784$

$h = 0.4392m$

From the equation above

$T = 2 \pi \sqrt{\frac{2.7571}{10 .72 * 9.81 * 0.4392} }$

$T = 1,534\ sec$

A rock falls for 1.43 seconds how far did it fall? The falls's velocity is an acceleration of -9.81 m/s2

BartSMP [9]

Answer:

$s = -0.100 \ m$

Explanation:

Generally from kinematics equations we have that

$s = ut + \frac{1}{2}gt^2$

Here u is the initial velocity of the rock and the value is 0 m/s given that there was no information that it was in motion before the fall

substituting 1.43 s for t and $-9.8m/s^2$ for g we have that

$s = 0 *1.43 + \frac{1}{2}(-9.8)*(0.143)^2$

=> $s = -0.100 \ m$

The negative sign show that the displacement is in the direction of the negative y-axis

Quasar spectra often show many absorption lines that all appear to be as a result of the same electron transition (such as level

Elanso [62]

Answer: Because of different redshift of cloud.

Explanation:

We are seeing absorption lines from clouds of gas that lie between us and the quasar, and therefore each cloud has a different redshift.

A quasar's spectrum is hugely redshifted. And most astronomers think this large redshift tells us about the distance to the quasar.
