the characteristics are magnification, attitude, location and type diverging is when the rays radiate outward from the focus converging is when the rays radiate inward so they cross each other

yea i think those as well

i think that they are both virtual and that their put through different types of lenses

images in a diverging lens are always virtual. when an objectis placed betweenthe focus and optical centre of a converging lens, the image is also virtual. what are the differences between these virtual images? explain by studying the 4 characteristics of each image. i have no idea of...

ammonia reacts with sulfuric acid to form the important fertilizer, ammonium sulfate. what mass of ammonium sulfate can be produced from 75.0kL of ammonia at 10°C and 110 kPa? k so i actually have no idea of what to do, honestly we've never covered this in my class before and we have a test o...

gravimetric stoichiomerty... eh? HELP calculate the mass of iron(III) oxide (rust) produced by the reaction of 500g of iron with oxygen from the air so i have no idea what do do here, my teacher sucks monkeys balls. so i thought to do the mass of iron(III) oxide divided by the 500g...

thanks guys! it was on one of the practice tests that my teacher wrote out for us, this helped alot! :)

what will be the rate of acceleration be when a 10N force is applied to a 7.0kg block of wood resting on a table with a coefficient of friction equalling 0.45? ok so i am totally confused, I am thinking i have to use 2 formulas but I am not exactly sure i tried the formula: Fn = Fg = mg...

how would you find the rate of acceleration when given the force, mass, and the coefficient of friction?? what would the formula(s) be?? i am so confused! HELP!
