In the attached image, we can see the free body diagram. And using the second law of Newton it will be possible to find the acceleration of the box.
Answer:
Explanation:
The density of an object is given by
where
m is the mass of the object
V is its volume
In this problem,
m = 42 kg
V = 22 m^3
Substituting into the equation, we find the object's density:
Answer:
Explanation:
Given
Initial Intensity of light is S
when an un-polarized light is Passed through a Polarizer then its intensity reduced to half.
When it is passed through a second Polarizer with its transmission axis
here
When it is passed through third Polarizer with its axis to first but
to second thus
When middle sheet is absent then Final Intensity will be zero
