What we have so far:
*Distance you walked the dog = 0.75 miles
*Conversion: 1 mile is approximately 1.61 kilometers
What we are trying to find:
*Distance you walked the dog in kilometers.
To solve this problem we must:
*We must employ conversion first.
Step 1) 0.75miles x 1.61km/1miles <--- Multiplication will be employed.
Step 2) 0.75 x 1.61/1 (km)<--- notice that we deleted the unit "miles". We did that to make sure that the result will be in kilometers (km).
Step 3) 0.75 x 1.61(km) <--- Since we are already done with the conversion process, we now have to multiply the distance and the conversion factor.
Step 4) 1.2075km <--- Raw result.
Step 5) Rounding it up to two decimal places: 1.21km
Therefore, the correct answer is: D. 1.21km
Answer:
light waves can be converted to electricity through <em>a solar cell</em>
Explanation:
Answer:
Wavelength, 
Explanation:
Given that,
Width of the slit, 
The angle between the first dark fringes on either side of the central maximum is 34 degrees
To find,
The wavelength of the light used.
Solution,
The equation of maxima is given by :
n = 1 here
So, the wavelength of the light used is 
. Hence, this is the required solution.
Answer: Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.
