Given that,
Time period of simple pendulum is 1.55 s.
Time period of simple pendulum for A student =1.25 s
Time period of simple pendulum for B student =1.5 s
We know that
The accuracy is defined as how close a measurement is to a known value .
The result of student of A is 1.25 s. It is more precise because it has more significant figure than student B's result of 1.6 s.
But the measurement made by student B's is much closer the known value of 1.55 s.
Hence, The most probable source of error is the result of student A.
Ok here's a rough image of how a typical energy diagram works. You give a little energy (A) and you get the potential that was in there all along. Kinda like pushing a big rock off a cliff. You do a little work then get a lot of energy out as the PE turns into other forms. In a match it's heat and light
Density of a material depends upon it's mass & volume.
You can calculate it by: Density = Mass / Volume
Hope this helps!
