By definition, we have that the mechanical advantage is given by the following equation:
Where,
W: is the load
T: is the tension
Substituting the values in the given equation we have:
Therefore, the mechanical advantage is equal to 5.
Answer: The mechanical advantage of this machine is: MA = 5
Answer and Explanation:
Comparison between the Titan's atmosphere and earth atmosphere
- Titan atmosphere is more denser than the earth atmosphere
- The quantity of nitrogen is more in titan atmosphere than earth atmosphere titan atmosphere have about 98 % of nitrogen in the other hand earth atmosphere has only 78 %
- There are no oxygen present in titan atmosphere while in earth atmosphere it is present
- Its air is not suitable for breath but in earth atmosphere we can breath

Answer: a) for 150 Angstroms 6.63 *10^-3 eV; b) for 5 Angstroms 6.02 eV
Explanation: To solve this problem we have to use the relationship given by De Broglie as:
λ =p/h where p is the momentum and h the Planck constant
if we consider the energy given by acceleration tube for the electrons given by: E: e ΔV so is equal to kinetic energy of electrons p^2/2m
Finally we have:
eΔV=p^2/2m= h^2/(2*m*λ^2)
replacing we obtained the above values.
