Answer:
q=1.7346×10⁻⁶C
Explanation:
Since the electric field is perpendicular to the bottom and top of the cube,the total flux is equals the flux over the top of surface plus the flex over the lower surface
Ф(total)=Ф₃₀₀+Ф₂₃₀
But the flux is given by Ф=E.A=EACos(θ) where θ is the angle between Area vector and electric field
So
Ф(total)=E₃₀₀A Cos(180)+E₂₃₀ACos(0)
Ф(total)=A(E₃₀₀ - E₂₃₀)
The total flux is given by Gauss Law as:
Ф(total)=q/ε₀
q=ε₀Ф(total)
q=ε₀(A(E₃₀₀ - E₂₃₀))
Substitute the given values
q=(8.85×10⁻¹²){(70²)(100 - 60)}
q=1.7346×10⁻⁶C
Since this is definitely a RIGHT triangle (the little square in the corner),
the hypotenuse is 15, 'h' is the side opposite the 38-degree angle, and
sin(38°) = h / 15
Multiply each side by 15: h = 15 sin(38°)
= 15 (0.616)
h = 9.235
Answer:
C. Every element contains one type of atom.
Explanation:
Every atom can be labeled as only one kind of element. So there are gold atoms, iron atoms and so on. When you say "this element" it is basically the same as saying "this atom" or "This type of atom" So C is right.
Answer:
Medium 1 is air and Medium 2 is water because the light slows down.
Explanation:
Light is known to slow down in water since water is denser than air.
Producido a partir de un experimento de laboratorio ido mal, las tortugas adolescentes Leonardo, Michelangelo, Donatello y Raphael viven en las alcantarillas bajo Nueva York. Aunque su sensei roedor, Splinter, aconseja no mostrarse sobre el suelo, los hermanos amantes de la justicia y que comen pizza no pueden permanecer ociosos mientras el malvado Shredder y sus secuaces aterrorizan a la ciudad. Con ayuda de la intrépida reportera April O'Neil (Megan Fox) y su camarógrafo (Will Arnett), las Tortugas salieron a salvar a Nueva York.
