first convert 5 mm to cm recall that 10 mm = 1 cm thus 5 mm = 1/2 cm = 0.5 cm then we subtract the thickness by the outer diameter: 41 - 2*0.5 41 - 1 = 40 cm hope this helps~ :)

"The strength of a cable is proportional to the square of its diameter." A 2-cm cable has a diameter of 2 cm, and a 3-cm cable has a diameter of 3 cm. If a 2-cm cable supports 800kg, so a 3-cm cable supports: 800*(3/2)² =?

Science 10
I am doing my science 10 by correspondence and I came upon a question that puzzles me. Why are modern light microscopes called Compound microscopes. That and How would I "determine theactual size of the cells shown in the illistration if the field diameter measures 2.2 mm...

a) The number density of He atoms under those conditions is n = 6*10^23 atoms/24.4 liters = 2.4*10^19 atom/cm^3 The volume per atom is 1/n = 4*10^-20 cm^2 and the average distance between molecules is the cube root of that, or 3.5*10^-7 cm. b. The average momentum of the He ...

A capacitor is made from two 1.2 cm diameter coins separated by a 0.18 mm thick piece of paper (K = 3.7). A 6 V battery is connected to the capacitor. How much charge is on each coin? My solution: C= K * Permitivity * A/d = q/v I solved for q and got 1.2 X 10^-10 But i still ...

F = G m Me/r^2 potential energy relative to zero at infinity = -G m Me/r here r = 84600 miles convert that to meters then potential energy lost = Kinetic energy gained G m Me/r = (1/2)m v^2 so v^2 = 2 G Me/r for part b you need m diameter = 2*10^3 so diameter/2 = radius = 1,...
