Answer;
= 0.018 mm
Explanation;
Mass = 12 ounces
1 ounce = 28.4 g
thus mass in g = 12 × 28.4 = 340.8 g
Volume = mass/density
= 340.8 g /2.70 g/cm³
= 126 cm³
The thickness from volume and area;
thickness = volume/ area
Area = 75 square ft
1 Square ft = 929.03 square centimeter
Thickness = 126 cm³/ (75 × 929.03)
= 0.001808 cm
but, 1 cm = 10 mm
Therefore; 0.001808 ×10 = 0.01808 mm
= 0.018 mm ( 3 decimal places)
Since Sal drew the electron dot diagram of an aluminum atom, Sal should;
C. He should add a single dot below the symbol.
If you know the height of the ship while in calm water,you can subtract the height of the ship with aware at its peak point and it will tell yoi how tall the wave is.
The current in the circuit is Zero is true
Define current
An electrical charge carrier flow known as current often involves electrons or atoms lacking in electrons. negative to positive points are crossed by current.
The maximum voltage across the resistor is the first choice. This choice is incorrect because, after a considerable amount of time, the capacity is fully charged and the circuit's current "I" will be equal to zero. Moreover, because current is 0 It will now be equal to zero for the voltage courses resistive "IR."
The next option claims that the voltage across the capacitor is at its lowest. Additionally, this is incorrect because charge across a capacitor reaches its maximum over time. In addition to being maximum, voltage will be maximum and equivalent to charge upon capabilities.
No The capacitor is only partially charged, according to the next option. This is incorrect since it takes a while for the charge to reach its maximum level before the maximum current is claimed. . Which is also incorrect because once the capacitor is fully charged, current eventually zeroes out.
Since the capacitor's charge did not change at all after it reached full charge, the fact that the circuit's current is zero is accurate. Because the charge has achieved its maximum value, the rate of change of charge will be zero, and the current will also be zero.

Answer:
655 nm
Explanation:
When the intereference is destructive then the thickness, d of antireflective film coating one side is given by
2d=w/2n
Where w is wavelength and n is the reflective index of the film
Making w the subject of formula then
w=4nd
Substituting 1.25 for n and 131 nm for d then the wavelength will be
w=4*1.25*131=655 nm
Therefore, the wavelength is equivalent to 655 nm
