Answer:
option E
Explanation:
given,
Parallax angle(d) = 1 arcsecond
using Parallax formula
p is the parsecs angle which is measured in 1 arcsecond
d is the distance in parsec
now,
we know,
1 parsec = 3.26 light year
hence, the answer will be option E
Answer:
The oscillation frequency of the spring is 1.66 Hz.
Explanation:
Let m is the mass of the object that is suspended vertically from a support. The potential energy stored in the spring is given by :
k is the spring constant
x is the distance to the lowest point form the initial position.
When the object reaches the highest point, the stored potential energy stored in the spring gets converted to the potential energy.
Equating these two energies,
.............(1)
The expression for the oscillation frequency is given by :
(from equation (1))
f = 1.66 Hz
So, the oscillation frequency of the spring is 1.66 Hz. Hence, this is the required solution.
As per Newton's II law we know that
here we know that
now the mass of the object will be given as
so mass of the object will be 13.3 kg
