Poor visibility, difficulties in colour perception, lessened colour contrast vision due to darker shadows and reduced peripheral vision, these are the reasons why one has to be extra careful while driving during hours of sunrise, sunset and night time.  

<h3><u> Explanation: </u></h3>

Sunrise, sunset and night time are parts of the day with minimal or absolutely no presence of sunlight. To safely navigate roads, we require enough light in order to detect presence of other vehicles, signs and pedestrians. Less sunlight during sunrise and sunset light the sky but makes the roads and vehicles have a darker, less bright view. The contrast between colours is the least, making it difficult to identify objects and see clearly.  

A rising or a setting sun can also lead to glares on the driver’s view and thus obstruct it. Since a change in ambient light is observed, our eyes need to adjust with this change and this isn’t spontaneous. Night time driving has headlight glares from approaching vehicles and reduced surrounding visibility. The eyes switching for vision adaptability from dark to bright light if vehicles approach and pass by is not a quick action. Hence the driver’s vision is compromised in every such case and this may lead to accidents.

in a tall building, a certain window is 500 meters above the ground.A tennis ball is catapulted horizontally out of the window w
expeople1 [14]

The tennis ball lands at a point 40.4 m from the base of the building.

The tennis ball is projected with a horizontal velocity <em>u</em> from a window, which is at a height <em>y</em> from the ground. The ball lands at a distance <em>x</em> from the base of the building. Let the ball take a time <em>t</em> to reach the ground. In the time <em>t</em> ,the ball falls a vertical distance <em>y</em> and also travel a horizontal distance <em>x</em>.

The initial vertical velocity of the ball is zero, since the ball is projected in the horizontal direction.  The ball falls down under the action of gravitational force.

Thus, use the equation of motion,

y=\frac{1}{2} gt^2

rewrite the expression for <em>t</em> and calculate the value of <em>t</em> using 9.81 m/s²for <em>g</em> and 500 m for <em>y</em>.

t=\sqrt{\frac{2y}{g} } \\ =\sqrt\frac{(2)(500m)}{9.81m/s^2}  \\ =10.096 s

The horizontal distance <em>x</em> is traveled using the constant velocity <em>u </em>since no force acts on the ball in the horizontal direction.

Therefore,

x=ut

Substitute 4 m/s for <em>u</em> and 10.096 s for <em>t</em>

x=ut\\ =(4m/s)(10.096s)\\ =40.384m=40.4 m

Thus, the ball lands at a point 40.4 m from the base of the building.

Which quantities appear in the equation for the magnetic field component of an electromagnetic wave?
tankabanditka [31]

Answer:

The speed of light (c)

Explanation:

The equation that relates the magnetic field component of an electromagnetic wave the the electric field component of the wave is:

E=cB

where

E is the magnitude of the electric field component

B is the magnitude of the magnetic field component

c is the speed of light in a vacuum, whose value is

c=3.0 \cdot 10^8 m/s

Re-arranging the equation to solve for B, we find:

B=\frac{E}{c}

Which of the following will not reduce water pollution?
Rina8888 [55]

Answer:

A. Using artificial fertilizers instead of composting

Explanation:

Composting is actually more better than fertilizers usually, as it takes natural waste and with help of nature, returning the nutrients into soil once again. However, Artificial fertilizers usually uses chemicals to ensure that weed does not grow, and may contain other "unnatural" ingredients to ensure that only the crop grows on the field. Because of the usage of non-natural ingredients, any run-off can prove to be detrimental to any animals that eat any of the run-off infected material, or drink the polluted water.
