Beta decay is exclusively the emission of electrons ... or its
oppositely charged relative, the positron ... from an atomic
nucleus.
Beta-minus is the emission of an electron, with a negative charge.
The change in the mass of the nucleus, if any, is minuscule.
The mass number of a nucleus is the sum of its protons and
neutrons, and the mass of an emitted electron is something
like 0.0005 the mass of one of those.
Answer:
The number of protons 6.19 more than electron.
Explanation:
Given that,
Charge 
We know that,
formula of charge
Where,
Q = total charge
n = number of protons
e = charge of electron
Put the value into the formula
According to statement of question
Divide the answer by 
Hence, The number of protons 6.19 more than electron.
Answer:
The answer is A.
Explanation:
To measure a temperature, you have degrees with Farenheight or Celsius. Meters are measured with a meter stick while grams and kilograms are measurments for weight.
Therefore, degrees Celsius is your answer.
Best of Luck to you!
They'll still be magnets, but they'll never be able to touch each other where they were cut.
I hope this helps you! :-)
You don't need to do any calculations, you are already given that n=1.5
n is index of refraction. it's 1.5
