Answer:

if you don't its still right though
Step-by-step explanation:
only if you don't simplyfy if you do then just subtract and you will get a another answer which both are right
Answer:
From the analysis W1=W2.
they are directly related
Step-by-step explanation:
the work-done in stretching a spring can be expressed as

where k= spring constant
x= change on length of spring
Hence for W1
Given data
x= 34-24= 10 cm
solving in terms of k we have

Hence for W2
Given data
x= 44-34= 10 cm
solving in terms of k we have

Answer:
A, 1,2
Step-by-step explanation:
we translate it first into language of math
we use n for the number
n² = 3n - 2
then, do some algebra things
n² - 3n + 2 = 0
then factorize it
(n - 2)(n - 1) = 0
first n
n - 2 = 0
n = 2
2nd n
n - 1 = 0
n = 1
so n can be 1 or 2
P=4πlr²
r²=P/4πl
r=√(P/4πl)= 1/2*(√(P/πl)
Answer is A
