Answer:
The frequency shift detected is
Explanation:
From the question we are told that
The normal frequency of the state highway patrol radar guns 
The speed of approach is 
Now the frequency measure by the the state highway patrol radar guns as your car approaches is mathematically represented as

Where c is the speed of light which a has constant value of

Now

=>
substituting values

Answer:
Final velocity of the object(v) = 114 m/s
Explanation:
Given:
Initial velocity (u) = 14 m/s
Accelerates (a) = 5 m/s²
Time taken = 20 seconds
Find:
Final velocity of the object(v) = ?
Computation:
According to 1st law of motion.
⇒ v = u +at
⇒ v = 14 + (5)(20)
⇒ v = 14 + 100
⇒ v = 114 m/s
Final velocity of the object(v) = 114 m/s
Answer:
Electron shell
Nucleus
Neutrons
Explanation:
An atom is made up of three fundamental subatomic particles which are the protons, neutrons and electrons.
- Protons are the positively charged particles. Neutrons do not carry any charges.
- Both protons and neutrons are found in the tiny nucleus at the center of that atom.
- The electrons are negatively charged.
- They are found outside the nucleus in electronic shells.
Answer:
The reactive part of a circuit changes electrical energy into another form of energy.
Explanation:
The reactive part of a circuit changes electrical energy into another form of energy.
The inductive part of a circuit changes electrical energy to magnetic energy and the capacitive part of a circuit changes electrical energy to electrostatic energy.
Answer:
Their velocity after the impact is 20.85 m/s.
Explanation:
Given that,
Mass of falcon, 
Mass of dove, 
Initial speed of the falcon, 
Initial speed of the dove, 
We need to find the final velocity after the impact. When the falcon catches the dove, it will becomes the case of inelastic collision. The conservation of momentum will be :

So, their velocity after the impact is 20.85 m/s.
