AI fountain of water is located at the centre of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 15 m. Next, the student stands at edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55°. how high is the fountain? ​

i'm thinking more like energy

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

gravitational energy

electrical energy

kinetic energy

ligh energy
