4. Given three vectors . A=i- 2k, B = 2i+k and C = -2j then what is the value of (A×B)×C

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
