1. We the answer in question in the form A(1+B)^0.5 and we can do that by factorising out the 5. This gives 5^0.5(1+0.4x)^0.5. 2. Identify the formula we are going to use ...

The first ionisation energy of an element is the amount of energy required to remove the outermost electron. This increases across the peroid as there is an increase in proton number so higher nuclear cha...

Rate of reaction is determined by the number of successful collisions between the reactants per second. A collision is successful if two particles collide with enough energy to react. This can be affected...

Learning theory is a credible approach to attachment as it is founded in pre-existing scientific theory, that the association between the satisfaction of needs and the person satisfying the need will lead...

The formula you are given is an equation which is written in terms of x. So we will be differentiating with respect to x. 

When differentiating we take the current power and place that in front of ...
