5 0

Answer: C. Tissue Paper

Explanation:

When we talk about objects that are illuminated by a light source, they are classified according to the amount of light they let through them, as follows:

Transparent bodies: Those who let in almost all the light that incides them. Therefore, the intensity of the incident light is very similar to that transmitted.  For example: Clear Glass

Opaque bodies: Those who do not let the light pass.  For example: Cream Cheese and Orange Juice

Translucent bodies: Those that let in a portion of the incident light. That is, they let approximately half of the light that falls on them pass through. For example: Tissue Paper

The correct equation for the x component of a vector named A with an angle measured from the x axis would be which of the follow
Lady_Fox [76]

Answer:

Acosθ

Explanation:

The x-component of a vector is defined as :

Magnitude * cosine of the angle

Maginitude * cosθ

The magnitude is represented as A

Hence, horizontal, x - component of the vector is :

Acosθ

Furthermore,

The y-component is taken as the sin of the of the angle multiplied by the magnitude

Vertical, y component : Asinθ

In Figure 21-4 B, does the magnetic field -due to the current carrying wire- curve in a clockwise or counter-clockwise direction
weeeeeb [17]

The magnetic field between the poles of the horseshoe magnet in fig 21.4 B curves in the <u>counter clockwise direction.</u>

The magnetic field lines due to a straight current carrying conductor is given by the right hand thumb rule.  This rule is stated as follows: Imagine holding the current carrying conductor in your right hand with the thumb pointing in the direction of current, then the direction in which your fingers curve around the wire gives the direction of the magnetic field lines. The direction of the magnetic field lines at a point gives the direction of magnetic field at that point.

On applying this rule, it can be seen that the magnetic field  due to the conductor shown in Fig 21.4 B curves in the counter clockwise direction.

zhuklara [117]

Complete Question

You stand on a straight desert road at night and observe a vehicle approaching. This vehicle is equipped with two small headlights that are 0.681 m apart. At what distance, in kilometres, are you marginally able to discern that there are two headlights rather than a single light source?Take the wavelength of the light to be 549 nm and your pupil diameter as 4.63 mm.  

Answer:

The distance is  z  = 4707.6 \ m

Explanation:

From the question we are told that

    The is distance between the headlight is d = 0.681 \ m

   The wavelength is  \lambda = 549 \ nm = 549 *10^{-9} \ m

    The  pupil diameter is  D  = 4.63 \ mm = 0.00463 \ m

Generally, we can mathematically evaluate the resolution of the eye as

            \theta  = \frac{1.22 *  \lambda }{D}

    substituting values

              \theta  = \frac{1.22 *  549 *10^{-9} }{0.00463}

              \theta  =  (1.45 *10^{-4} )^o

Now according to SOHCAHTOA rule  

         sin \theta  =  \frac{ d}{z}

Where z is  the distance at which the eye can discern the two head light

  given that the angle is very small sin \theta =  \theta

=>    \theta  =  \frac{ d}{z}

substituting values

     1.45*10^{-4}  =  \frac{ 0.681}{z}

=>   z  = \frac{0.681}{1.45 *10^{-4}}

=>    z  = 4707.6 \ m

Astronauts who traveled to the moon were able to float slightly as they walked along its surface. Why were the astronauts able t
Maslowich

Answer:

the weight of astronauts on earth is greater than his weight on d moon

Explanation:

due to the greater gravitational pull in earth the weight seems to me more

but for the moon where there is less gravity

its weight will be less causing slight flotation
