The lid is removed when the water begins to boil the immersion heater transfers 1.1 3 MJ of energy to evaporate all of the water calculate the specific latent heat of vaporisation of water

i think it's 35 meters

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
