D. 980, this is the best answer because 35 x 7 is 980 :)
As it is given that Bulk modulus and density related to velocity of sound
by rearranging the equation we can say
now we need to find the SI unit of Bulk modulus here
we can find it by plug in the units of density and speed here
so SI unit will be
SO above is the SI unit of bulk Modulus
I think you would be using a topographic Map, So the answer should be A
The number of protons in an atom is known as the atomic number
A. molecules are CONSTANTLY moving.
