Answer:
when there is no water in the atmosphere or when no drops are formed there is no rainbow..
he hydrogen transition lines would be missing in the visible range, the RED region
Explanation:
The sunlight that reaches the Earth is scattered by the atmosphere and radiated, as the atmosphere has mainly nitrogen, the radiated light is blue, this light does not produce a rainbow.
The sunlight must reach a drop of water that disperses the colors according to the refractive index of the water and in this way produces a rainbow, so when there is no water in the atmosphere or when no drops are formed there is no rainbow..
If the atmosphere were composed of Hydrogen, the hydrogen transition lines would be missing in the visible range, this corresponds to the so-called Balmer series and they are in the RED light region.
Answer:
Option C. 20 V
Explanation:
We'll begin by calculating the equivalent resistance of the circuit. This can be obtained as follow:
Resistor 1 (R₁) = 20 Ω
Resistor 2 (R₂) = 40 Ω
Resistor 3 (R₃) = 60 Ω
Equivalent Resistance (R) =?
R = R₁ + R₂ + R₃ (series arrangement)
R = 20 + 40 + 60
R = 120 Ω
Next, we shall determine the current in the circuit. This can be obtained as follow:
Voltage (V) = 60 V
Equivalent Resistance (R) = 120 Ω
Current (I) =?
V = IR
60 = I × 120
Divide both side by 120
I = 60 / 120
I = 0.5 A
Finally, we shall determine the potential drop across R₂. This can be obtained as follow:
Current (I) = 0.5 A
Resistor 2 (R₂) = 40 Ω
Voltage (V) =?
V = IR₂
V = 0.5 × 40
V = 20 V
Therefore, the potential drop across R₂ is 20 V
The answer is that
a would be going at a high speed and if b is just standing there then b would be getting applied forced on it so b would straight wherever a pushes it
Explanation:
A technique in which the muscles are stretched by an outside force is called Passive Stretching
