Answer:
l = 10.16 m
Explanation:
In this case, we have the period of oscillation of the pendulum is 6.4 s. It is required to find the height of the tower.
We know that the pendulum executes SHM. Let l is the height of the tower. The time period of simple pendulum is given by :
g is acceleration due to gravity
We need to rearrange the above equation such that,
So, the height of the tower is 10.16 m.
Answer:
Ration of internal energy of hydrogen to the internal energy of helium is equal to
Explanation:
As we know
degree of freedom of hydrogen is 5
Degree of freedom of helium is 3
Internal energy of hydrogen
Internal energy of helium
Ration of internal energy of hydrogen to the internal energy of helium is equal to
