Answer:
there is ZERO TRANSMISSION through the polarizer.
Explanation:
Given the data in the question;
waves was polarized in the x direction propagate towards an ideal polarizer whose axis is aligned with the y-axis.
so θ = 90° { aligned with the y-axis }
now, we know that for polarized light going at angle θ to the polarizer;
I = I₀ × cos²θ
Where I₀ is the intensity of unpolarized light.
I is the intensity after polarization.
so we substitute the value of θ
I = I₀ × cos²( 90° )
I = I₀ × 0
I = 0
Therefore, there is ZERO TRANSMISSION through the polarizer.
Answer: the loneliest whale relates to the communication that whales give to each other
Explanation: whales have different forms of communication , and the ‘loneliest’ whale can’t get any company by the other whales.
In other words: it may be a new and different way whales communicate, nobody knows much about the loneliest whale. It may be forming a new kind of communication
Explanation :
It is given that,
Potential energy, 
Power dissipated, 
We know that the power dissipated is given by :

I is the current passing through the phone.



or
I = 0.018 A
Hence, the current that passes through the phone is (1) 0.018 A.
Answer:
The ice melts mass is:

Explanation:
Kinetic Energy



Heat gained by ice= mass(g) x 80 cal
( 1 cal = 4.184 *10^7er or g cm^2/ sec^2)
Assuming no loss in heat, in the motion so both continue with temperature 0~C
To find so the mass (gm) of ice melted
