18.5164213 if you divide them both you get that number so the volceity is the number shown above.
<u>Answer:</u>
<em>When red light enters the lens its wavelength decreases but its frequency remains the same.
</em>
<u>Explanation:</u>
Lens is made of glass which is a <em>denser medium</em> when compared with air. Thus light will undergo refraction and bend toward the normal. On entering a denser medium from rarer medium the speed of light decreases.
<em>Speed, frequency and wavelength of an electromagnetic wave</em> are related according to the equation.
<em> v=ϑλ
</em>
Where is <em>v is the frequency, λ is the wavelength and v is the speed of the em wave.
</em>
On entering the lens the wavelength of the red light as well as speed decreases but the<em> frequency remains the same.

Answer:
2.4m/s towards the bowling pins
Explanation:
Given parameters:
Mass of the ball = 6.6kg
Momentum of the ball = 15.9kgm/s
Unknown:
Speed of the ball = ?
Solution:
The momentum is the amount of motion a body posses;
Momentum = mas x velocity
Insert the parameters and solve;
15.9 = 6.6 x velocity
velocity = 2.4m/s towards the bowling pins
Answer:
2,421,666 miles
Explanation:
light travels 186,282 miles per second in a vaccum.
So 186,282 × 13 = 2,421,666
Answer:
2465 J/g
Explanation:
The amount of energy required to boil a sample of water already at boiling point is given by
where
m is the mass of the water sample
is the specific latent heat of vaporization of water
In this problem, we know
Solving the equation for , we find
