The free-body diagram is missing, but I assume the only forces acting on the box are the force F pushing the box, the weight of the object and the normal reaction of the surface.
Since the weight and the normal reaction acts in the vertical (y) direction, the only force acting on the box in the horizontal (x) direction is the horizontal component of the force F, which is given by
And so this is the net force in the x-direction.
Answer:distance divided by time

Answer:
The value is 
Explanation:
From the question we are told that
The depth is 
The time taken for water to fall to below the river is 
The horizontal distance from the base of the vertical cliff is 
Generally the horizontal speed at the top is mathematically represented as
=> 
=>
Gravity is pulling the book towards the center of the earth, and the rebounding effect of the table cancelling out gravity allowing for the book to sit at rest.
For conversion, there are 3,785.41 mL for every 1 gallon.
Volume = 305 gal (3,785.41mL/gal) = 1,154,550.05 mL
The equivalent mass of the solution would be:
1,154,550.05 mL *0.9811 g/mL = 1,132,729.054 g
Ratio = 1,132,729.054 g/ (96 +4) = 11327.29
Thus, the total amount of solute in the mixture is:
Amount of solute = 4*11327.29 = 45,309.16 g
The molar mass of ammonia is 17 g/mol.
Amount of mol of solute = 45,309.16 g/ 17 g/mol = 2,665.24 mol
Since molarity is mol solute per liter,
Molarity = 2,665.24 mol/[1,154,550.05 mL(1 L/1000 mL)]
<em>Molarity = 2.308 M</em>
