We can use Pythagoras theorem for it.
Pythagoras theorem is
The square of the hypotenuse (longest side) equals to the square of the other sides added together.
b^2 + x^2 = a^2
So we just substitute the numbers given into the equation.
12^2 + x^2 = 13^2
144 + x^2 = 169
X^2 = 25
X = 5
Therfore the answer is 5 cm

balandron [24]

Water could be made to boil at 105 degrees Celsius instead of 100 degrees Celsius by taking the sample to a higher altitude. Pressure is directly proportional to temperature. So when you bring water into higher altitude, you are increasing the external pressure and therefore increase the boiling point.

The option that would be appropriate to model nuclear fission is disturbing a drop of water such that it breaks into smaller droplets

Nuclear fission refers to the splitting of a heavy nucleus into lighter nuclei owing to the bombardment of small particle.

The liquid drop model provides the most apt model for describing the concept of nuclear fission. In nuclear fission, the nucleus breaks due to the increase in repulsion between the nuclear charges.

As the size of the nucleus continues to increase, any little disruption will; result in the breaking up of the nucleus into smaller fragment called daughter nuclei.

Hence, the model of disturbing a drop of water such that it breaks into smaller droplets is the most apt description of nuclear fission.
