Answer:
Explanation:
A )
Th expression for time period for a spring -mass system is as follows
T = 2π
So if mass is doubled , Time period will be √2 or 1.414 times or 5.9 s
B )
If the mass is halved , time period becomes 1 / √2 times or .70 times or 3.0 s
C)
Time period does not depend upon the amplitude of oscillation . So in this case time period will be unchanged ie 4.2 s
D )
As per the formula above , if spring constant k is doubled , time period will be 1 / √2 times or .70 times or 3.0 s
