Answer:
Photovoltaic cell or solar cells
Explanation:
Solar cells are cells that converts light energy from the sun into electrical energy for use in appliances. Light energy impinges on these cells, the photons of light causes electrons in the solar cells to move thereby resulting in the production of electricity in the cells.
Answer:
only 2 electrons can be occupied in atomic orbital.
Answer:
The concentration is 0.036 mg/mL
Explanation:
Concentration = 0.2 mM = 0.2/1000 = 2×10^-4 M = 2×10^-4 mol/L × 180,000 mg/1 mol × 1 L/1000 mL = 0.036 mg/mL
Answer:
Explanation:
<u>According to Arrhenius concept of acid and base:</u>
"When a base in a solution, produces/yields OH- (Hydroxide) ions."
So, when a base is dissolved in a solution, it produces OH- ions.
<u>For example:</u>
NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

It will be air friction which is also known as (resistance) because a 10-n force is going down and a 2-n force is slowing it down so there is resistance because the 2-n force is acting upon the 10-n force
