Two balls have the same mass of 5.00 kg. Suppose that these two balls are attached to a rigid massless rod of length 2L, where L

olga_2 [115]

Answer:

Explanation:

Given

mass of balls $m= 5 kg$

$N=45.6 rev/s$

angular velocity $\omega =2\pi N=286.55 rad/s$

Length of Rod $2L=1.1 m$

Tension in the Second half of rod

$T_2=m\omega ^2(2L)=2m\omega ^2L$

$T_2=5\times (286.55)^2\times 1.1$

$T_2=451.609 kN$

For First Part

$T_1-T_2=m\omega ^2L$

$T_1=T_2+m\omega ^2L$

$T_1=3 m\omega ^2L$

$T_1=3\times 5\times (286.55)^2\times 0.55$

$T_1=677.41 kN$

is incident on a polarizer whose transmission axis makes an angle of 30o with respect to the horizontal. What is the average int

postnew [5]

Answer:

Explanation:

Let the incident intensity of light on the polariser is Io.

Let the angle of transmission is θ.

According to the law of Malus,

The intensity of light coming out form the polariser is given by

I = IoCos²θ

The mean or the average value of Cos²θ is 1/2

So, the intensity of light coming out from the polariser is

I = Io/2

Thus, the 50% of light is transmitted by the polariser.

A dolphin accelerates at -1.77m/s^2 for 3.33s and ends with a velocity of -8.77m/s. What is the displacement of the dolphin in t

Irina-Kira [14]

vf=vi+at

8.77=vi+1.77 x 3.33

8.77 = vi+5.8941

vi=2.8759

vf²=vi²+2ad

8.77²=2.8759²+2x 1.77 x d

76.9129=8.27 + 3.54d

d=19.39 m
