Answer:
d. the translucence of the object
Explanation:
the reason is that an object has a particular color as it is translucent to certain colors; it may absorb some colors and not show them at all, or they will reflect the remaining colors, the ones we are able to see. for eg: imagine you have a red dress. you see it as red, yet it is only reflecting the red color into your eyes, and is absorbing every other color in that light's color spectrum.

Answer:
The Richter Scale is used to define the power of earthquakes, it was created by Charles Ritcher in the 1930s to work as a seismogram, regulated and assessed by a seismometer, which responds to ground motions at a distance of around 62 miles from the event, and records the seismograph, a <em>base 10</em> logarithmic scale.
Thereby the most suitable options are <em>A)</em><em>, </em><em>B)</em><em> </em>&<em> </em><em>D)</em><em>.</em>
Answer:
It takes you 32.27 seconds to travel 121 m using the speed ramp
Explanation:
<em>Lets explain how to solve the problem</em>
- The speed ramp has a length of 121 m and is moving at a speed of
2.2 m/s relative to the ground
- That means the speed of the ramp is 2.2 m/s
- You can cover the same distance in 78 seconds when walking on
the ground
<em>Lets find your speed on the ground</em>
Speed = Distance ÷ Time
The distance is 121 meters
The time is 78 seconds
Your speed on the ground = 121 ÷ 78 = 1.55 m/s
If you walk at the same rate with respect to the speed ramp that
you walk on the ground
That means you walk with speed 1.55 m/s and the ramp moves by
speed 2.2 m/s
So your speed using the ramp = 2.2 + 1.55 = 3.75 m/s
Now we want to find the time you will take to travel 121 meters using
the speed ramp
Time = Distance ÷ speed
Distance = 121 meters
Speed 3.75 m/s
Time = 121 ÷ 3.75 = 32.27 seconds
It takes you 32.27 seconds to travel 121 m using the speed ramp
