<span>The Halogen outer layer is considered to be full with eight electrons. Halogen is also considered to be part of the Noble gases classification. The exchange of electrons in the halogen atom renders a photon energy pulse with produces light. The consentrated light spectrum is produced in the halogen light bulbs and halogen laser products.</span>
You could change your velocity by altering both your speed and direction.
For example, if you are running north at 10 miles per hour, and turn into a street going east, then slow down to 5 miles per hour, you would have changed your velocity.
Answer:
square root of 2gh
Explanation:
gh=(1/2)(v^2)
dividing both sides by 1/2, we have
2gh=v^2
therefore;
v=square root of 2gh
The acceleration due to gravity on a large body is given by:
acceleration = (gravitational constant * mass of body) / radius²
For b, this is:
g = GM/r²
M = gr²/G
For a,
g(a) = 1/6 g
r(a) = 1/4 r
M(a) = g(a)r(a)²/G
M(a) = 1/6 g * (1/4 r)²/G
M(a) = gr²/96G
The fraction is given as:
M(a) / M = (gr²/96G) / (gr²/G)
M(a) / M = 1/96
The mass of planet a is 1/96 of the mass of planet b.
Answer: 0.213m
Explanation: The fundamental frequency is 805Hz.
The second harmonic (first overtone ) is 1035 Hz and the third harmonic (second overtone) is 1265 Hz.
The pipe is an air filled hence it is a closed pipe
Recall that v = f λ
At fundamental frequency
Where v = speed of sound in air (v) = 343 m/s
Fundamental frequency (f) = 805 Hz
Wavelength ( λ) = ?
By substituting the parameters, we have that
343 = 805 × λ
λ = 343 / 805
λ = 0.426m
The pipe is an open one and at the fundamental frequency, hence the relationship between wavelength ( λ) and length of air is given as
L = λ/4
But λ = 0.426m
L = 0.426/2
L = 0.213m
