Answer:
velocity and wavelength
Explanation:
When a ray of light moves from one medium to another, the ray of light changes the direction when it enters the second medium, refraction of light occurs.
When it changes the direction, the frequency will remain the same because it depends only on the source not on the medium.
As the refractive index of two medium is not same, it means the wavelength will change.
Also, speed = frequency × wavelength
So, wavelength and velocity changes. Hence, the correct option is (a).
Firstly, when we say precision, this means the level of detail of a number. On the other hand, significance means that how precise a number is written and accuracy is defined as how close the number is to an actual value. Significant figures represent the precision of a measurement and not its accuracy because when a measurement has a larger number of significant figures, it has a greater reproducibility <span>or precision because it has a smaller source of error in the estimated digit. Hope this answer helps.</span>
Answer: c , striker
Explanation:Strikers are considered the best all-around players. They must be adept at accurate passing as well as precision shooting with both feet. The wingers (right and left outside forwards) are similar to basketball guards. These play- ers must be able to control the ball in order to score the maximum number of points.
Answer:
<u>a)</u>24.73 m/s
b)58.56°
Explanation:
<u>given:</u>
<u></u>
=20.7 m/s
t=49 s
a=0.3
<u>solution:</u>
<u>a) </u>
<u></u> = 
= 20.7 m/s
=0
<u>
</u>
= + at
= 0 + 49 x 0.3
= 14.7 m/s
<em><u>
</u></em><u><em>magnitude:</em></u>
=
=24.73 m/s
<u>
b)</u>
angle =tan-1 
= 58.56°
