Graphs because it has a lot of squares and it accelerates to 35 km/h in 20 seconds
Labels that belong in regions marked X and Y are;
A) X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically hard ferromagnetic material
Answer:
T = 0.71 seconds
Explanation:
Given data:
mass m = 1Kg, spring constant K = 78 N/m, time period of oscillation T = 0.71 seconds.
We have to calculate time period when this same spring-mass system oscillates vertically.
As we know

This relation of time period is true under every orientation of the spring-mass system, whether horizontal, vertical, angled or inclined. Therefore, time period of the same spring-mass system oscillating vertically too remains the same.
Therefore, T = 0.71 seconds
