when you 5x automatically cancels, and 7.5 / 3 is 2.5
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

(2x2) + 4((3x2)/2) = 4 + 12 = 16 in^2
Answer:
Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative. When you divide two integers with the same sign, the result is always positive.
