This problem can be solved by using elimination.Label 3x + y = 11 as equation (1) and 2x + y = 8 as equation (2).We first want to eliminate one of the variables so that we can then reach a value for the o...

If you are unsure of the number of solutions to an equation, it is always best to start with a diagram. By drawing a diagram then marking out the boundaries specified in the question, it is easy to visual...

Compliance: Changing public behaviour but not private beliefs in order to fit in with the group. Identification: Changing public behaviour and private beliefs but only when WITH the group. Internalisation...

Both gravitational and electric field obey inverse square laws (e.g. F(grav)=GMm/r^2 and F(electric)=kq1q2/r^2 where GMm and kq1q2 are constants). They both act between two bodies without any means of con...

Neurons use a sodium potassium pump to maintain a resting potential in the body. Inside a cell normally, there are more sodium in the cell and fewer potassium outside the cell, and hence there is a negati...
