Answer:
a) zero b) zero
Explanation:
Newton's first law tells us that a body remains at rest or in uniform rectilinear motion, if a net force is not applied on it, that is, if there are no applied forces or If the sum of forces acting is zero. In this case there is a body that moves with uniform rectilinear motion which implies that there is no net force.
Answer:
dislocations play an important role in controlling as
Explanation:
As dislocations plays an important role in the ductility, elasticity and plurality of materials
- The elastic and elastic deflections play a large role in their properties as the metallic materials, because the dislocation of a glass material does not play a major role in their properties.
Open system because there is mass (water) flowing through the system of interest (radiator)
