If the sound source is approaching you, the frequency you hear is higher than the real frequency of by the sound. How much higher depends on how fast the source is approaching. If the source's speed is constant, then the frequency you hear is constant ... higher, but not increasing.

52.1-4.184=47.916 You then either add or subtract this from 68.6 the first temperature of the metal. This will give you your total.
Answer:
a
The mass is
b
The velocity is
Explanation:
From the question we are told that
The speed of the protons is
The mass of the protons is
The speed of the rebounding protons are
The negative sign shows that it is moving in the opposite direction
Now according to the law of energy conservation mass of one nucleus of the unknown element. is mathematically represented as
Where is the mass of a single proton
So substituting values
The mass of on proton is
So
Now according to the law of linear momentum conservation the speed of the unknown nucleus immediately after such a collision is mathematically evaluated as
Now because before collision the the nucleus was at rest
So
=>
Recall that
So
=>
substituting values
