Answer:
The net force acting on the box is 2N to the left.
Explanation:
The net force acting that is on an object is the sum of all of the individual forces acting on it.
If two forces act on an object in opposite directions, the net force is the difference between the two forces. In this case, the net force is always greater than or equal to zero but less than either of the individual forces.
If two forces act on an object in the same direction, the net force is the sum of the two forces. In this case, the net force is always greater than either of the individual forces.
Here in the figure the two forces acting in opposite direction on the object.
The direction of the resultant force is same direction as the force with the larger magnitude
Thus the net force is 2N to the left
Explanation:
It is known that the molecular weight of ammonia () is as follows.
Molecular weight () = = 17
(a) Therefore, we will calculate the mass as follows.
= 8500 g
Now, formula to calculate weight of the system in N is as follows.
Weight = mass × g
=
= 83.3 N (1 = 1 N)
Hence, the weight of the system is 83.3 N.
(b) Relation between specific volume and number of moles is as follows.
Therefore, calculate the specific volume as follows.
= 12
Also,
v =
= 0.705882
Therefore, we can conclude that the value of specific volume is 12 and 0.705882 .

Answer:
The pressure exerted by the girl is 245,000 N/m²
Explanation:
Given;
mass of the girl, m = 50 kg
area of the girl's shoe, A = 0.002 m²
The pressure exerted by the girl is calculated as follows;
Therefore, the pressure exerted by the girl is 245,000 N/m²
1. Mary is 500 Meters away from her starting point because the hypotenuse represents the displacement of Mary from A to O.
2. Since Mary took the long way, she walked a total of 700 Meters. (Because she went from A to O to B, and the sum of 300 and 400 is 700).
3. Mary walked 140 Meters per minute, because S=D/T. so speed = 700 divided by 5, 140.
