Hypothesis: The water will squirt far.
Indep.V.: Height of hole.
Depend.V.: Range of squirt
Constant: Everything that isnt the independant var. such as filled liquid.
Control: None,I believe.
Number of groups: 4
Trials per group: 4
Answer:
The answer is A. There is no electric field on the interior of the conducting sphere.
Explanation:
A solid conducting sphere in a uniform electric field will exert force on the charges in the sphere to redistribute themselves in such a way that both the charges and the field inside the sphere would vanish.
Voltage = (current) x (resistance)
The voltage across THIS RESISTOR is
V = (0.050 A) x (0.1 ohm)
V = 0.005 v (5 millivolts)
The formula should be (2πr)/T. r=radius T=time. if time is in seconds the formula would look like this
Answer:
a) n = 1.33, b) t = 87 10⁻⁹ m
Explanation:
Part A.
The thin anti-reflection film should create destructive interference for the desired wavelength.
2t sin θ = (m + ½) λₙ
The 2 goes out of the path of the beam inside the film, lam is the wavelength modulated by the refractive index of the film
λₙ = λ₀ / n
2t = (m + ½) λ₀ / n
n = (m+ ½) λ₀/2t
Suppose we are in the first inference m = 0
n = (½ 480 10-9)/ 2 90
n = 1.33
Part B
We do not know the refractive index of the glass explicitly, but in general it is of the order of 1.5, so since the index of the film is lower, there is no phase change.
2t = (m + ½) λ₀ / n
t = 1/4 480 10⁻⁹ / 1.38
t = 87 10⁻⁹ m
