yes rock freak, my equation is not supposed to be perfect it is supposed to come close the the specific heat. i got 136, the answer in the book is 130. thank you guys again

Ok thanks guys, and i am sorry if i have not fully explained. i guess i should pay more attention in class. and i will work on explaining myself more on posts to come.

I am doing a lab about specific heat. i have a cup of boiling water which i put 5 metals into, and a cup of warm water which sits at 22 degrees celcius. i am to record the difference in temperature as i am using the equation Q = mc (delta) T for part one, and then i am using the equation C = Q/m...

i got stuck because the units were not right . i converted grams into kilograms = .45kg and centimetres into metres = .08m . .45kg x .08m = .036N (Newtons)

' a mass of 450 grams is given an acceleration of 8cm/s/s. Calculate the net force required. so confused, the only question i couldn't get was this one.

yeah i went to my physics class and found out that my teacher had missed that. i got (.2)(9.8)(2) = 3.9m/s

' On wet pavement, a car can be accelerated with a maximum acceleration a = .20 g before its tires slip. ' a) starting from rest, how fast is it moving after 2.0s b)how far has it moved after 4.0s i have looked over this question plenty of times and have never got the right answer. i have...

and the y intercept is where the line crosses the y-axis right?

i am currently taking physics 11. i have seen this equation before, but my class is at such a fast pace i couldn't fully learn what this equation ment. i am working on a position time graph, what exactly does this equation mean? what does the letter " b " resemble?

the units are position ( km ) and time ( h ) . the curve accelerates and then stops at one hour. i would like to say sorry, as i am not as smart as you. you seem very intelligent.

i have a position time graph, going from 0 - 1.0. going up by .1 each centimetre on my metric graph paper. at first i am asked to find how fast the object is moving at .1 hours. the answer is 5.0km/h. i understood that, but then i am asked to find how fast it was for the first .5h . with this...

finding the velocity of a time that does not start at 0. i have the answer but i do not know how to do it. do i use a tangent or go from point one to point two? sorry for being the least bit descriptive, I'm not a genius.
