Your roommate gives you a cylindrical can of peanut brittle, saying that she got it for free as a promotion at the grocery store,and that she doesn’t like it because it sticks to her teeth. Just as you are about to open it, you remember that it is April 1...

A rod of length L has a varying density along its length that satisfies: λ(x) =((x^2/L^2)+1)λo where x = 0 is one end of the rod (which has density λo), and x = L is the other end (which has density 2λo). a. Find mass of the rod in terms of L and λo. b. S...

Two horizontal turntables are in contact with each other at their outer edges, and the static friction between them allows them to turn together (in opposite directions) without slipping. Thelarger turntable has a radius of 0.36m, and the smaller turntabl...

i have changed name just for safety purpose i am using this site for the very first time i wont do it again kindly answer my question

what will be the final answer of this

i am not getting the point,can you elaborate more

and for rate of surface area increasing?

kindly i need the complete solution of it

after interval its not sorry its only "t"

(reiny) i need help please

reiny i need help please

what will be the final answer of part c?

kindly help its urgent , i have done 24 questions this one is left i have to submit the assignment within an hour please help

help please asap

B is the answer brother

bobpursely can you help me please

actually there is another issue i don't have angle to find out volume of fluid, now i have height,weight,diamter of cylinder and need to find height of fluid? Kindly help damon

i think volume can be calculated by mass/density? I think i got it kindly confirm please ! and thank you so much

apply Diagonal = sqrt(length^2 + width^2)

mingfas present age is 2. Enjoy!

i know its answer, which is 3.74, but i have no idea how does it can be 3.74

yes mingfas is 2 and his father is 32 , after 4 years mingfas will be 6 and his father will be 36. so the square of mingfas age will be 36 which will be exactly the age of his father

thank you steve
