Answer:
Doppler effect.
Explanation:
The velocity of the moving car affects the wavelengths of the reflecting radio waves according to the principle of Doppler effect. Therefore, for a car moving away from the radar gun, the wavelength of the radio waves is increased, and for a car moving towards the gun, the wavelength is decreased. The degree of increase or decreases depends on the speed of the car, so if you know how much a wavelength has changed, you know the velocity of the car.
Answer:
White light is composed by a range of colors, this was discovered by Isaac Newton when he observed that a beam of white light was refracted (the different rays of light are diverted depending on their wavelengths) when passing through a prism . This phenomenon was later called dispersion
Answer:
Correct answer: V₀ = 9.9 m/s
Explanation:
The subject is a vertical upward shot.
We will use the following formula:
V₀² = 2 · g · h => V₀ = √2 · g · h , where V₀ is initial velocity
V₀ = √2 · 9.81 · 5 = √ 10 · 9.81 = √98.1 = 9.9 m/s
V₀ = 9.9 m/s

The brush passes current from a power source into the commutator. Therefore they both must carry electric current, B
Answer:
Potential energy.
Explanation:
Batteries are a form of chemical energy which is stored in the bonds of molecules contained within the battery acid, batteries are a form of potential energy making chemical potential energy too.
