You shine unpolarized light with intensity 52.0 W/m2 on an ideal polarizer, and then the light that emerges from this polarizer

kondor19780726 [428]

Answer:

The intensity of light from the first polarizer is $I_1 = 26 W/m^2$

Explanation:

The intensity of the unpolarized light is $I_o = 52.0 \ W/m^2$

Generally the intensity of light that emerges from the first polarized light is

$I_1 = \frac{I_o}{2 }$

substituting values

$I_1 = \frac{52. 0}{2 }$

$I_1 = 26 W/m^2$

1. Two astronauts are 2.00 m apart in their spaceship. One speaks to the other. The conversation is transmitted to earth via ele

Veronika [31]

Answer:

$1.6949*10^6 m$

Explanation:

Our values are

$d=2m$

$v=354m/s$

We can find the time through

$t=\frac{d}{v}$

$t=\frac{2}{354}$

$t=5.64*10^{-3}s$

The expression for the distance between the Earth and the spaceship is as follow:

$d=ct$

Where c is Light speed, and t our previous time.

$d= (3*10^8)(5.64*10^{-3})$

$d= 1.6949*10^6m$

Therefore the distance between the Eath and the Spaceship is $1.6949*10^6$ m

A baseball has 5.8kg*m/s momentum before being hit by the bat. After being hit it has 6.79 kg*m/s in the opposite direction. Wha

fomenos

Answer:

0.99kgm/s

Explanation:

Given parameters:

Initial momentum = 5.8kgm/s

Final momentum = 6.79kgm/s

Unknown:

Magnitude of the impulse applied to the baseball = ?

Solution:

To solve this problem;

The impulse applied to the baseball can be found by using the expression below:

Impulse = Final momentum - Initial momentum

Impulse = 6.79kgm/s - 5.8kgm/s = 0.99kgm/s

One end of a string 6.26 m long is moved up and down with simple harmonic motion at a frequency of 95 Hz . The waves reach the o

uranmaximum [27]

Answer:

Explanation:

Given

length of string $L=6.26\ m$

frequency $f=95\ Hz$

time taken by wave to reach at other end $t=0.5\ s$

speed of wave is given by

$v=\frac{length\ of\ string}{time\ taken}$

$v=\frac{6.26}{0.5}$

$v=12.52\ m/s$

wavelength of is given by

$\lambda =\frac{velocity}{frequency}$

$\lambda =\frac{12.52}{95}$

$\lambda =0.131\ m$
