1. A spring of spring constant k = 12 .5 N/m is hung vertically. A 0.500 kg mass is then suspended from the spring.?

F = delta(l) k delta(l) = F/ k and F = m g delta(l) = m * g / k = 0.500 kg * 9.81 N/kg / 12 .5 N/m = 0.3924 m or 39.2 cm to 3 sig figs If someone ...

5. A spring has a natural length of 7ft, and a force of 12 pounds stretches it 1 ft Find the work done in stretch?

k = 12 /1 = 12 pounds/ft When the spring is stretched from... from 9.5 - 7 = 2.5 ft to 13 - 7 = 6 ft Work done = 1/2 * k * (x2^2 - x1^2) = 1/2 * 12 * (6^2 - 2.5^2) = 178.5 pound-ft ____________.

7. Why aren't quarks taught in the K - 12 curriculum?

As far as I'm aware, most high school physics classes tend to focus on classical mechanics or Newtonian physics, of which quarks hold little relevance until you start studying objects at a quantum level. Most people will...

8. A series combination of a 12 k resistor and an unknown capacitor is connected to a 11 V battery.?

V(t) = V(0)*[1-e^(t/RC)], we have 8 = 12 *[1 - e^(-1/RC)] or 0.6667 = 1 - e^(-1/RC) or e^(-1/RC) = 0.3334 or -1/RC = ln{0.3334) = -1.0996 or RC = 0.910 or C = 0.910/12000 = 27.78 microfarad

9. How would you recreate a model of the Solar System other than using a 50 meter tape?

styraphome balls ranging in different size, medal wiring(medal clothes hanger), paint and build from there. if you want to get real sophisticated, use a flashlight for the sun, its good with explaing the phases of the moon :)

10. A spring with spring constant k = 800 N/m is extended 12 cm from its equilibrium position. A spring with 6.0 c

ans e) 3200 N/m reason : it is bcoz,potential energy of a spring=1/2. k .x^2 for first spring, k =800 N/m , x= 12 cm for second spring, k =? , x=6 cm equating & solving the equation,we get 3200 N/m ans.
