If Voq doubles, abN gets multiplied by 16 .
If Voq=3, abN=81 .
Answer:
b) the refracted ray has an angle of 90 degrees
Explanation:
The angle of incidence is measured with respect to the normal separation of the media. The critical angle for total internal reflection occurs is:
Here 
and 
are the refractive index of the mediums. This equation is an application of Snell's law, for the case where the refracted ray has an angle of 
.
Answer:
B. An opposing force caused by friction produced a lower acceleration than calculated
Explanation:
Answer:
0.4
Explanation:
Because 3m/s is the initial velocity(u) and 5m/s is the final velocity(v) and time is 5 sec.
So, acceleration = v-u ÷ t

Answer:
22.5 miles due North
38.7 miles due East
Explanation:
From the information given above, we infer :
Let there be a <u>vector <em>AB</em></u><em> </em>(indicating distance travelled) with <em><u>magnitude = 45 </u><u>mi</u></em><u> </u> and makes an angle of <em>30° with East axis</em> as well as an angle of <em>60° with North axis</em>.
<u>Displacement covered in North Direction </u><u>:</u>
AB Cos 60° = <em><u>22.5 miles due North </u></em>
<u>Displacement covered in East Direction</u> :
AB Cos 30° = <em><u>38.7 miles due East</u></em>
