State four advantages of Mercury over alcohol as thermometric liquids​
Gemiola [76]

Answer:

  • Alcohol wets glass while mercury doesn't
  • Alcohol has a lower boiling point and hence cannot be used to measure very high temperature.
  • Alcohol is colorless and is very difficult to read without coloration.
  • Mercury's expansion is uniform.

Marisa does 3.2J of work to lower the window shade in
Pani-rosa [81]

Work is considered as the Force performed on a body to move it a certain distance, that is

W = Fd

Here

W = Work

F = Force

d = Distance

In this case we have the values of work and distance, therefore clearing for the Force we would have to

F = \frac{W}{d}

Replacing,

F = \frac{3.2J}{8m}

F = 0.4N

Therefore the force that Marissa must exert on the windows shade is 0.4N

You deposit a thin film of magnesium difluoride on a glass lens (n >1.60), reducing the reflection of yellow light, at normal
JulsSmile [24]

To solve this problem it is necessary to apply the concepts related to destructive interference.

The concept refers to an overlap of two or more waves of identical or similar frequency that, when interfering, creates a new pattern of waves of lower intensity

By definition destructive interference is given by

2Mt = (n+\frac{1}{2})\lambda

Where,

\lambda= wavelength

n=integer (1,2,3,4,5,6...etc)

t = thickness

M= Index of refrqaction

For minimum thickness to satisfy this condition n will be minimum there,

n=0

Therefore

2Mt = (0+\frac{1}{2})\lambda

Solving to find M,

M = \frac{\lambda}{4t}

M = \frac{585nm}{4*106nm}

M = 1.38

Therefore the correct answer is B. 1.38
