Answer:
Increases
Explanation:
Frequency and wavelength of lights are inversely proportional to each other.
The wave of light having highest frequency have shortest wavelength and the light with the shortest frequency having highest wavelength.
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Answer and explanation:
Elements of the same group have the same number of valence electrons, therefore they behave similarly. For example in group 2, alkaline earth metals, all the elements have two valence electrons.
Answer:
Robot 1 : 150 J
Robot 2: 40 J
Explanation:
30 N x 5m = 150 J
20 N x 2m = 40 J

Answer:
0.8°C
Explanation:
Given the following:
Trial 1 : freezing point of distilled water = 0.9°C
Trial 2: freezing point of distilled water = 0.7°C
The average freezing point of distilled water is the sum of the two freezing points obtained divided by 2 ;
(Trial 1 + trial 2) / 2
(0.9°C + 0.7°C) / 2
1.6°C / 2
= 0.8°C
