How a typical human eye sees color?

Light receptors within the eye transmit messages to the brain. This produces the familiar sensations of color. Newton observed that color is not inherent in objects. Instead, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.

5. Annie drags her little red wagon with a mass of 5.00 kg, up a hill that has an angle of

maxonik [38]

Answer: $25.08\ m/s^2$

Explanation:

Given

mass of wagon m=5 kg

elevation

$\theta =30.9^{\circ}\\F=150\ N$

Sin component of weight will oppose the applied force therefore we can write

$F-W\sin \theta=ma\\where\\W=weight(mg)\\a=acceleration$

$150-5\times 9.8\times \sin (30.09)^{\circ}=5\times a\\125.43=5a\\a=25.08\ m/s^2$

Hook's law describes an ideal spring. Many real springs are better described by the restoring force (FSp)s=−kΔs−q(Δs)^3, where q

kvasek [131]

Answer

given,

k = 250 N/m

q = 900 N/m³

(FSp)s=−kΔs−q(Δs)^3

work done = Force x displacement

$W = \int {F. dx}$

limits are x = 0 to x = 0.15 m

work done

$W = \int_0^{0.15} (k x + q x^3)\ dx$

$W = [\dfrac{kx^2}{2}+\dfrac{qx^4}{4}+ C]_0^0.15$

$W = \dfrac{300\times 0.15^2}{2}+\dfrac{900\times 0.15^4}{4}$

W = 3.375 + 0.1139

W = 3.3488 J

b) % cubic term = $\dfrac{0.1139}{3.3488}$

% cubic term = $3.4\ %$

After a projectile is fired into the air, what is the acceleration in the x-direction? (Assume no air resistance.)

Gre4nikov [31]

Without air resistance, there is no horizontal force on the projectile,
so it has no horizontal acceleration. The answer is "zero".

Sherita has a mass of 50 kg and slowly climbs up a 5 m high flight of stairs how much work dose sherita do in ascending the stai

elixir [45]

Work done = Mass * displacement
W = 50 * 5 = 250 watts

In short, Your Answer would be 250 watts

Hope this helps!
