A force of 10 pounds stretches a spring 2 inches. Find the work done in stretching this spring 3 inches beyond its natural length

physics
So I need to multiply by 10 not e? Is that right? So the answer should be 7.32e26

physics
I came out with 1.99e26 and I got it wrong. What is the point of multiplying by e?

physics
How many coulombs of positive charge are in 3.8 mol of O2 gas?

physics
A double-slit interference pattern is created by two narrow slits spaced 0.21 mm apart. The distance between the first and the fifth minimum on a screen 55 cm behind the slits is 6 mm. What is the wavelength of the light used in this experiment? Having trouble setting this up....

950 + 550 does not equal 2000. try an equation set equal to 2000 and go from there

physics
ok, so I came out with 293.3N...what am I doing wrong???

The lowest note on a grand piano has a frequency of 28.1 Hz. The entire string is 2.00 m long and has a mass of 440 g The vibrating section of the string is 1.90 m long. What tension is needed to tune this string properly?

physics
Thank you so very much Damon!
