i'm having trouble grasping what happened in the Solomon islands 'tensions' could you help me understand the main points/events whatever thanx

explain why must the ramp be angled initially to get a starting height

a threatened species means that the numbers of that species are getting low but not quite verging on extinction where as an endangered species is on the verge of extingtion

is this a right angle triangle? if it is you can find the hypotenuse which is the longest side of the triangle using Pythagoras theorem a(squared)+b(squared)=c(squared) c=hypotenuse 20(squared)+48(squared)=c(squared) 400+2304=c(squared) 2704=c(squared) (s...

-6-[-2-5(squared)]= =-6-[-2-25]= =-6-(-23)= =-23+6 =-17

oops sorry i havn't done this in a while thanx bobpursley -6-(-2-5^2)= =-6-(-2-25)= =-6-(-27)= (negatives cancel) =-6+27= =27-6= =21

singly ionized hydrogen (positive)- correct one proton doubly ionized hydrogen(positive)- two protons and two neutrons would be helium not hydrogen, did you mean to write hydrogen? because you cant doubly ionize hydrogen positively singly ionized oxygen (...

fat i think

tan 20(degrees)=Opposite/Adjacent =O/12.5 12.5tan20(degrees)=O O=horizontal

north west--|--east south on your vector diagram draw a line going east(right) mark 50km the 30km north(up) for 30degrees east of north imagine a line going straight up(north) then measure 30degreese towards where east would be and make the line 25km once...

conclusion?

well did the dissolved oxygen levels go down with the rise in temperature or did they go up or did they stay the same in your experiment

no all wrong
