Given
width of window 
height of window 
standard atmospheric pressure 
Also 
Thus Net Force on the window will be the algebraic sum of Force due to outside and inside Pressure .
Answer:
a). Single replacement.
Explanation:
Because one element replaces another element in a compound
That is false

1st derivative gives velocity;
d r(t)/ dt = 2t i + 6 j + 4/t k
2nd derivative gives acceleration;
d^2 r(t)/ dt^2 = 2 i - 4/ t^2
Speed ;
Square root of (4 t^2 + 36 + 16/ t^2)
For a given time, like 2 seconds, t will be 2. And answer of speed will be scalar.
Solid and liquids are much more denser than gas because their molecules are close to each other and with that the molecules of them can't move that freely unlike the gas molecules. Also, because of being near to each other the molecules of solid and liquids became heavy making them dense.
