Answer:

2.39×10¯⁵ m²

Explanation:

From the question given above, the following data were obtained:

Distance (d) = 8.08×10¯⁵ m

Charge (q) = 2.24×10¯⁹ C

Potential difference = 855 V

Area(A) =?

NOTE: Permittivity (ε₀) = 8.854×10¯¹² F/m

The area can be obtained as follow:

q = ε₀AV/d

2.24×10¯⁹ = 8.854×10¯¹² × A × 855 / 8.08×10¯⁵

2.24×10¯⁹ = 7.57×10¯⁹ × A / 8.08×10¯⁵

Cross multiply

7.75×10¯⁹ × A = 2.24×10¯⁹ × 8.08×10¯⁵

7.75×10¯⁹ × A = 1.81×10¯¹³

Divide both side by 7.75×10¯⁹

A = 1.81×10¯¹³ / 7.75×10¯⁹

A = 2.39×10¯⁵ m²

Thus, the area of the plate is 2.34×10¯⁵ m²

What is Molecular mass?​
MArishka [77]

Answer:

Molecular mass is the amount of mass associated with a molecule. It is also called as molecular weight. It can be calculated by adding the mass of each atom multiplied by the number of atoms of the element present in the molecule. For example, water is made up of 2 hydrogen atoms and 1 oxygen atom.

Which color in the rainbow has the longest wavelength? 1. orange 2. blue3. yellow4.green 5. red
rodikova [14]

In rainbow, the color that has the longest wavelength is red which means option 5 is the correct choice.

Dispersion is described to be the spreading of white mild into its complete spectrum of colors, in truth we also can say a complete spectrum of wavelengths. The white mild turns into from solar and includes seven colors. On one end of the spectrum is red with the longest wavelength. Blue or violet mild has the shortest wavelength. White mild is a aggregate of all hues withinside the color spectrum. The colors of the rainbow are: Red, orange, yellow, green, blue, indigo, violet.

Therefore, option 5 is the correct choice.
