Forces are considered balanced when all of the combined forces lead to no change in the motion of the object. For example, when a book is sitting on a table, the force of gravity is pushing downward and the normal force is pushing upward with exactly the same amount of force. Since they are equal and opposite forces, the book does not move.
Unbalanced forces exist when there are unequal forces acting upon the object, which leads to a change in the state of motion. Unbalanced forces can lead to a change in direction, a change in speed, or both a change in direction and in speed.
Answer:
Devni is correct
Explanation:
The relationship between pressure and density of a liquid is directly proportional i.e. the amount of pressure exerted on a liquid is directly proportional to its density and this is because when pressure is exerted the volume is compressed hence there will be a proportional increase in density as well.
hence pressure is as important as density in liquids
Explanation:
We know that rate of flow through a cross section :
5 m/s * 1.76cm^2 = v2 * 7.06cm^2
Angular momentum of a particle moving along a straight line is given by formula
now here particle is moving along a straight line with speed v along x direction
so here we can say
now we can say
here we know that
so angular momentum will be
The answer would be, "Granite".
