= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring

Learning & Memory 1. Learning Learning = relatively permanent change in behaviour due to experience 1. Learning • Definition implies learning takes place when there is change in behaviour • But changes in behaviour do not always mean learning has taken place • If we look at the definition the changes has to be permanent • This means it has to be long lasting as a result of experience • Most human behaviour is learned behaviour • We will discuss 3 types of

If there is any violation between the constraint and the data action‚ the action is aborted by the constraint. In SQL‚ we have the following constraints: NOT NULL - Indicates that a column cannot store NULL value UNIQUE - Ensures that each rows for a column must have a unique value PRIMARY KEY - A combination of a NOT NULL and UNIQUE. Ensures that

questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre
