(1 point) A frictionless spring with a 3-kg mass can be held stretched 1.6 meters beyond its natural length by a force of 90 new
Nonamiya [84]

Answer:

x(t)=0.337sin((5.929t)

Explanation:

A frictionless spring with a 3-kg mass can be held stretched 1.6 meters beyond its natural length by a force of 90 newtons. If the spring begins at its equilibrium position, but a push gives it an initial velocity of 2 m/sec, find the position of the mass after t seconds.

Solution. Let x(t) denote the position of the mass at time t. Then x satisfies the differential equation  

m \frac{d^{2}x}{dt^{2}} +kx=0

Definition of parameters  

m=mass 3kg

k=force constant

e=extension ,m

ω =angular frequency

k=90/1.6=56.25N/m

ω^2=k/m= 56.25/1.6

ω^2=35.15625

ω=5.929

General solution will be

x(t)=c1cos(ωt)+c2Sin(ωt)

x(t)=c1cos(5.929t)+c2Sin(5.929t)

differentiating x(t)

dx(t)=-5.929c1sin(5.929t)+5.929c2cos(5.929t)

when x(0)=0, gives c1=0

dx(t0)=2m/s gives c2=0.337

Therefore, the position of the mass after t seconds is  

x(t)=0.337sin((5.929t)

A scientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surf
Tasya [4]

Answer:

<em>The correct answer is (a) 312.5nm and (b) 125nm</em>

Explanation:

<em>The first step to take is to find The minimum thickness of the slick of the oil</em>

<em>Given that,</em>

<em>(a) tmin  λ/2n </em>

<em>We substitute 750nm ( in air) for λ and 1.20 for n for the expression of  minimum thickness t of the oil slick at that spot</em>

<em>thus,</em>

<em>tmin = (750nm)/2(1.2) = 312.5nm</em>

<em>The minimum thickness of the oil slick at that spot is =312.5nm</em>

<em>(B) we find the minimum thickness t </em>

<em>The minimum thickness of the oil slick at the spot will be calculated by,</em>

<em>tmin = λ/4n</em>

<em>we then 750nm ( in air) for λ and 1.50 for n  in the expression for the minimum thickness of the slick of the oil.</em>

<em>tmin = (750nm)/4 (1.5) = 125nm</em>

<em>Therefore the minimum thickness t will now be = 125nm</em>
