Cooking utensils, such as pots, pans and menu trays, are often made from aluminium because it is lightweight and conducts heat well, making it energy-efficient for heating and cooling. These properties also make it a preferred material for packaging.
Answer:
The value is 
Explanation:
From the question we are told that
The diameter of the nucleus is 
The charge of the proton that makes up the nucleus is 
The energy to be impacted is 
Generally the radius of the nucleus is mathematically represented as
=> 
=> 
Generally from the law energy conservation we have that
i.e
Here
Here 
is the initial kinetic energy which is mathematically represented as
Here 
is the initial potential energy of the proton and the value is 0 J given that the proton is moving
Also 
is mathematically represented as
Here
is the final potential energy which is mathematically represented as
Here 
is the charge on the proton with a value of 
So
=> 
So
=> 
Here m is the mass of the moving proton with value 
So
=> 
=>
Answer: 300 turns
Explanation: In order to explain this problem we have to consider the relationship between the voltage for the primiry and secondary and the turns for their coils.
This expression is consequence of the Faraday law because the magnetic flux is the same for both coils then the induced emf are the same for both circuits.
They are reñated as follow:
Vs=Vp*Ns/Np where Vs and Vp are the voltage for the secondary and primary coil, respectively.
Ns and Np are the turns for the secondary and primary coil, respectively.
Then we have:
Ns=Vs*Np/Vp= 16*2250/120=300
I think u would add them all up and then write down your answers
That's called the "red shift" of the star's spectrum, because red is the lowest frequency/longest wavelength in visible light.
