Answer:
The frequencies of the two lines are:
a) 
b)
When we heat rubidium compound we will see red color.
Explanation:

c = speed of light
= wavelength of light
a) Frequency of the light when wavelength is equal to 



This frequency corresponds to red light
b) Frequency of the light when wavelength is equal to 



This frequency corresponds to violet light
When we heat rubidium compound we will see red color.
Answer:
The weight of the object on earth =441N
Weight of the object on moon = 72N
Explanation:
Weight of a body is the product of its mass and acceleration due to gravity. Acceleration due to gravity varies between planetary bodies. The acceleration due to gravity on earth is 9.8 m/s² while on moon is 1.6m/s² and it goes different for others too.
Weight = Mass * acceleration due to gravity
Weight(e) = weight on earth
Weight (m) = weight on moon
Weight(e) = 45 * 9.8 = 441N
Weight (m) = 45 * 1.6 = 72N
Weight of a body is measured in a unit called Newton(N)
The concept that can be used in order to answer this item is that of the conservation of heat among the system. We let T be equal to the final temperature. The equation that would allow us to relate the initial and final conditions of both substances is as follows,
m₁cp₁(T - T₁) = m₂cp₂(T₂ - T)
The first entity, 1, is the milk and the second entity, 2, is the coffee. We are given that the specific heats of both substances are just equal so we can eliminate them from the equation. Substituting the known values,
(10 g)(T - 10°) = (1.60 x 10^2 g)(90° - T)
The value of T from the equation is 85.29°C.
Answer: 85.29°C
Answer:
The particles of the solid vibrate faster and faster. After a while, they can start to move around
Explanation: Solid particles movement are restricted due to the strong force of attraction between the molecules,Solid phase will only change to liquid phase if the forces of attraction holding the molecules together are broken down by heat, when this happens the solid particles movement will become more mobile as the substance is moving from solid phase and liquid phase
