a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
Answer:
a)693.821N/m
b)17.5g
Explanation:
We the Period T we can find the constant k,
That is
squaring on both sides,
where,
M=hanging mass, m = spring mass,
k =spring constant
T =time period
a) So for the equation we can compare, that is,
the hanging mass M is x here, so comparing the equation we know that
b) In order to find the mass of the spring we make similar process, so comparing,
