There are a number of theodicies used to defend the existence of God against the problem of evil and suffering. One such argument is called the free will defence and is advocated by Alvin Plantinga. He argue...

A piece of card is released from rest at a height of 0.5m above a light gate. It falls freely and a computer measures the velocity as it passes through the light gate to be 3.10m/s. What is the acceleration due to gravity measured by this experiment?

This question can be solved using suvat equations, since the acceleration due to gravity is constant. First make a list of the variables given in the question; s=0.5m u=0ms -1 (since the card is released fro...

If (2x+3)/(x-4)-(2x-8)/(2x+1)=1, what is x?

First eliminate fractions; Multiplying both sides by (x-4) gives; (2x+3)-((2x-8)(x-4))/(2x+1)=(x-4) Multiplying both sides by (2x+1) gives; (2x+3)(2x+1)-(2x-8)(x-4)=(x-4)(2x+1) Now simplify the expression; E...

A ball is thrown out of a window 18m off the ground. It is thrown horizontally at 0.5m/s. Show that it takes about 2s to reach the ground

Using the initial information we can see that the acceleration in the 'y' direction is equal to 'g', so from this we can work out the velocity in the 'y' direction 'V(y)' by simply integrating the accelerati...

The shortest side of a triangle is 4.3m long. Two of the angles are 45.1 and 51.2 degrees respectively. Find the length of the longest side.

To begin we calculate the third unknown angle in the triangle by taking the two known angles (45.1 and 51.2) away from 180 degrees (remember the interior angles of a triangle sum to 180). We find this angle ...
