The given question is incomplete. The complete question is as follows.
An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 36 possible sites for adsorption. Calculate the entropy of this system.
Explanation:
It is known that Boltzmann formula of entropy is as follows.
s = k ln W
where, k = Boltzmann constant
W = number of energetically equivalent possible microstates or configuration of the system
In the given case, W = 36. Now, we will put the given values into the above formula as follows.
s = k ln W
=
= 
Thus, we can conclude that the entropy of this system is

Answer:
The the maximum emf is 
Explanation:
Given that,
Magnetic field 
Frequency = 60 Hz
Diameter = 7.8 μm
We need to calculate the maximum emf
Using formula of emf

Where, N = number of turns
B= magnetic field
A = area
Put the value in to the formula


Hence, The the maximum emf is 
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
As we know that initially the grass hopper is at rest at the ground position
Now the acceleration is given as

distance of the legs that it stretched is given as

so we have



Part b)
time taken to reach this speed is given as



Part c)
as the grass hopper reach the maximum height its final speed would be zero
so we will have



I believe it is an electromagnet
