Based on the image, which is not a wavelength?
1 answer:
The distance that is not a wavelength in the image is C to E.
<h3>What is wavelength?</h3>Wavelength is the distance between two successive crests or two successive trough or crest to trough.
It is also the distance over which the wave's shape repeats.
Based on the image, the following are wavelengths;
- A to E, this is wavelength because it is between a crest and a trough.
- B to F, this is wavelength because it is between two successive crest.
- D to H, this is wavelength because it is between two successive trough.
Thus, the distance that is not a wavelength in the image is C to E.

Answer:
108.37°C
Explanation:
P₁ = Initial pressure = 101 kPa
V₁ = Initial volume = 530 m³
T₁ = Initial temperature = 10°C = 10+273.15 =283.15 K
P₂ = Final pressure = 101 kPa (because it is open to atmosphere)
V₂ = Final volume = 530 m³
P₁V₁ = n₁RT₁
⇒101×530 = n₁RT₁
⇒53530 J = n₁RT₁
P₂V₂ = n₂RT₂
⇒53530 J = n₂RT₂
Dividing the first two equations we get
∴Temperature must the air in the balloon be warmed before the balloon will lift off is 381.25-273.15 = 108.37°C
Answer:
The cup with 0.5L
Explanation:
To know what amount of water you take into account the specific heat of the water. The specific heat of water is:
Thus, 4186 J of energy are needed to icrease the temperature of 1 kg water in 1°C. Then, more grams of water will need more energy.
You have that one cup has 0.5 L and the other one has 750mL = 0.75L
The second cup of water will need more heat because the amount of water contained in the second cup is greater than in the first cup with 0.5L
