Linear momentum is a vector quantity defined as the product of an object’s mass and it's velocity
Answer:
685.6 J
Explanation:
The latent heat of vaporization of ammonia is
L = 1371.2 kJ/kg
mass of ammonia, m = 0.0005 Kg
Heat = mass x latent heat of vaporization
H = 0.0005 x 1371.2
H = 0.686 kJ
H = 685.6 J
Thus, the amount of heat required to vaporize the ammonia is 685.6 J.

Answer:
0 degrees
Explanation:
Let are two forces. The resultant of two forces acting on the same point is given by :
Where is the angle between two forces
When i.e. when two forces are parallel to each other,
When i.e. when two forces are parallel to each other,
When i.e. when two forces are parallel to each other,
It is clear that the resultant of two forces acting on the same point simultaneously will be the greatest when the angle between them is 0 degrees. Hence, this is the required solution.
