    How high above the table should the lamp be placed to achieve maximum

    I = k cos(?) / d² d² = y² + r², cos(?) = y / ?(y² + r²), I = k [y /?(y² + r²)][1/(y² + r²)] = ky / (y² + r²)^3/2 Now, set dI/dy = 0, and solve for the height, y. Hope this helps!

    What could cause a light scraping sound upon truck start-up and when accelerating?...

    ...It's a '96 Mazda B3000.? The sound just started happening yesterday when I started my truck to go home for lunch. When starting the sound lasts for just a couple seconds. Then I hear it again when accelerating. It doesn't seem to occur when my clutch is in or when idling. Like I said, it's...

    Discuss galvanic corrosion in the context of sacrificial corrosion protection,...

    In general, the further apart the materials are in the galvanic series, the higher the risk of galvanic corrosion, which should be prevented by design. Conversely, the farther one metal is from another, the greater the corrosion will be. Most cathodic and resistant to corrosion to least...

    What is the period of the pendulum ... physics help ?

    a) T = 2(pi)sqrt{ L/g} = 2(pi) sqrt{0.75/9.8} = 1.74 s b) T = 2(pi)sqrt{m/k} = 2(pi)sqrt{1.42/k} = 1.74 k = 1.42 / [(1.74/2(pi))^2] = 18.5 N/m

    Please help with this physics question?

    1 Angstrom = 10^-10 meters, applicable in the atomic realm (i.e. atomic radius). 1 micrometer or micron is equal to 10^-6 meters. Therefore, 1 Angstrom = 10^-4 micron 10^4 Angstrom = 1 micron = 1 micrometer

    An ideal gas absorbs 492 J of heat from its environment and does 824 J of work on the

    Use 1st Law of Thermodynamics: U = Q - W U = 492 - 824 = - 332 J => energy lost by the gas U = 332 J => energy added to the environment.

    Please help, test tomorrow!?

    T = Ia = I w / t, w = Tt / I = 3(8)/5 = 4.8 radians/s E = 0.5 I w^2 = 0.5(5)(4.8)^2 = 57.6 J note: T => torque I => moment of inertia a => angular acceleration w => angular velocity t => time E => kinetic energy
