How many phase conductors are installed between the switch and the light fixture shown in the figure? A. Four
B. Three
C. Two
D. Five
Answer:
TWO
Explanation:
While at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 23 s.A. What is your speed?
B. What is the magnitude of your acceleration?
C. What is the ratio of your weight at the top of the ride to yourweight while standing on the ground?
D. What is the ratio of your weight at the bottom of the ride toyour weight while standing on the ground?
Answer:
Explanation:
From the given information:
radius = 15 m
Time T = 23 s
a) Speed (v) = [tex]\dfrac{2 \pi r}{T}[/tex]
[tex]v = \dfrac{2\times \pi \times 15}{23}[/tex]
v = 4.10 m/s
b) The magnitude of the acceleration is:
[tex]a = \dfrac{v^2}{r} \\ \\ a = \dfrac{(4.10)^2}{15}[/tex]
a = 1.12 m/s²
c) True weight = mg
Apparent weight = normal force
From the top;
the normal force = upward direction,
weight is downward as well as the acceleration.
true weight - normal force = ma
apparent weight =mg - ma
[tex]\dfrac{apparent \ weight}{true \ weight} = \dfrac{(mg - ma)}{(mg)}[/tex]
[tex]=1- \dfrac{1.12}{9.8}[/tex]
= 0.886 m/s²
d)
From the bottom;
acceleration is upward, so:
apparent weight - true weight = ma
apparent weight = true weight + ma
[tex]\dfrac{apparent \ weight }{true \ weight} =\dfrac{ mg + ma}{mg}[/tex]
[tex]\dfrac{apparent \ weight }{true \ weight} =1+ \dfrac{a}{g} \\ \\ = 1 + \dfrac{1.12}{9.8}[/tex]
[tex]= 1 + \dfrac{1.12}{9.8} \\ \\[/tex]

define ohms laws and prism
Answer:
the ohms law says
Explanation:
ohm found that current, voltage, and resistance in a circuit are always related in the same day.
ohms obersivations
ohms found that if the factors that affect resistance are held constant, the resistance of most conductors does not depend on the voltage across them charging the voltage in a circuit changes the current but does not change the resistance regardless of the applied voltage. the ohms law resistance in a circuit is equal to voltage divided by current
resistance =current or voltage =current × resistance
A boundary with a small opening. There is a vector straight from the opening labeled D and an angle labeled theta to another ray, both striking a surface with a red point. The distance between the two red points is labeled y. A laser diffraction pattern results in y = 6.0 cm, and the distance from the gap to the screen is D = 12 cm. The tangent of θ would be equal to . Calculating the inverse (tan–1) of the value for the tangent of θ would give us a diffraction angle, θ, of degrees.
Answer:
The tangent of θ would be equal to 0.5
Calculating the inverse (tan–1) of the value for the tangent of θ would give us a diffraction angle, θ, of 27 degrees.

Which of Mendel principles would apply to mating two organisms that have two different alleles for three different traits
Answer:
Law of independent assortment
Explanation:
This is because law of independent assortment state that alleles of two or more genes when two organisms mate will be inherited or pass down to gametes which are in one way or the other independent of each other or each of the alleles. Therefore parent can have up to three different traits and the alleles can be inherited by the gametes.
Answer:
three different traits
Explanation:
just because it is.

Drake lifted a couch a height of 0.2 meters in 1.3 seconds. He did 300 j of work. how much power did drake use?
Answer:
c is correct
Explanation:
I hope this helps.
When Drake lifted a couch to a height of 0.2 meters in 1.3 seconds. He did 300 j of work then the power used by Drake is
What is work done?The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
Work Done = Force * Displacement
As given in the problem Drake lifted a couch at a height of 0.2 meters in 1.3 seconds. He did 300 j of work.
Work done by the drake = 300 J
Time taken by the drake to do the work = 1.3 seconds
By substituting the values of the work and time in the formula of power
Power = work done / time
= 300/1.3
= 230.77 Watt
Thus, the power used by Drake is 230.77 Watt

I threw a plastic ball in the pool for my dog to fetch. The mass of the ball was 125g. What must the volume be to have a density of 0.500g/mL
Answer:
250 mL
Explanation:
Density equation:
[tex]Density = \frac{mass}{volume}[/tex]
Variables:
D = density
m = mass
V = volume
Solve:
M = 125 g
D = 0.500 g/mL
V = ?
[tex]0.500 g/mL = \frac{125 g}{V}[/tex]
V = 250 mL

How many joules are needed to vaporize 125 g of liquid water at 100°C? The latent heat of vaporization is 2258 J/g.
Answer:
282,250 joules
Explanation:
Given that :
Mass of liquid water = 125 gram.
Latent heat of vaporization, L = 2258 J/g
Recall :
Q = mL
Where, Q = quantity of heat required in Joules
Mass) m
L = latent heat of vaporization
Q = mL
Q = 125 g * 2258j/g
Q = 282,250 joules
A mustang, has an average velocity of 33 m/s while covering a course that is 21 miles long. (1 mile = 1609 m). How long did it take the driver to complete the course?
Answer:
t = 1023.9 seconds
Explanation:
Given that,
The average velocity of a Mustang, v = 33m/s
Distance, d = 21 miles = 33789 m
Let the driver takes t seconds. So,
Speed = distance/time
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{33789}{33}\\\\t=1023.9\ s[/tex]
So, it will take 1023.9 seconds to complete the course.
a person walks 750m due north then 250 m due east of the entire walk takes 12 min find the person average velocity
Answer:
v = 1.098 m/s
Explanation:
Given that,
A person walks 750m due north then 250 m due east of the entire walk takes 12 min.
We need to find the average velocity of the person.
Displacement,
[tex]d=\sqrt{750^2+250^2} \\\\d=790.56\ m[/tex]
Average velocity = displacement/time
[tex]v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s[/tex]
So, the average velocity of the person is 1.098 m/s.
What is a wavelength of induced radiation quantum if 2-nd order diffraction maximum change on distancе 3.5 сm from сentral and distance between screen to diffraction lattice 0.5 m? Lattice period 0.01 mm.
Answer:
λ = 3,5 10⁻⁷ m
Explanation:
El fenómeno de difracción es descrito por la expresión
a sin θ = m λ
usemos trigonometría para encontrar el sino
tan θ = y/L
tan θ = sin θ /cos θ
los experiemtos de difraccion ocurran para langulos pequeños
tan θ = sin θ
sin θ =y/L
substituimos
a y/L = m λ
λ = a y /m L
calculemos
λ = 0,01 10-3 0,035 / 2 0,5
λ = 3,5 10⁻⁷ m

What is the third harmonic
frequency that it produces?
(Speed of sound = 343 m/s)
(Unit = Hz)
please help me guys will give brainliest and lots of points
Answer: The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency.
Explanation: Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.
The speed of light in air is 3.00 x 10^8 m/s. If a light wave has a wavelength of 5.80 x 10^-7m, what is its frequency?
Answer:
5.17 x 10^14 1/s
Explanation:
Equation:
c = λ f
c = speed of light
λ = wavelength
f = frequency
Solve:
3.00 x 10^8 m/s = (5.80 x 10^-7m) * f
f = (3.00 x 10^8 m/s) / (5.80 x 10^-7m)
f = 5.17 x 10^14 1/s
