The angular velocity as a function of time is given by
\omega (t)=\gamma-\beta t^2
where \gamma=4.90 rad/s and \beta=0.750 rad/s^3. The angular acceleration as a function of time is equal to the derivative of the angular velocity. If we calculate the derivative of w(t), we find:
\alpha(t)= \frac{d\omega}{dt} =-2\beta t
<span>and this is the angular acceleration of the fan blade.</span>

Answer:

Angular acceleration, α = -2βt

Explanation:

Angular velocity of fan is \omega_{z(t)}=\gamma -\beta t^2

\gamma=4.90\ rad/s

\beta=0.750\ rad/s^3

Angular acceleration is given by :

\alpha=\dfrac{d\omega}{dt}

\alpha=\dfrac{d(\gamma -\beta t^2)}{dt}

\alpha=-2\beta t

Hence, the above equation is the angular acceleration as a function of time.

Answer:

V=14.9 m/s

Explanation:

In order to solve this problem, we are going to use the formulas of parabolic motion.

The velocity X-component of the ball is given by:

Vx=V*cos(\alpha)\\Vx=15.7*cos(31^o)=13.5m/s

The motion on the X axis is a constant velocity motion so:

t=\frac{d}{Vx}\\t=\frac{20.0}{13.5}=1.48s

The whole trajectory of the ball takes 1.48 seconds

We know that:

Vy=Voy+(a)*t\\Vy=15.7*sin(31^o)+(-9.8)*(1.48)=-6.42m/s

Knowing the X and Y components of the velocity, we can calculate its magnitude by:

V=\sqrt{Vx^2+Vy^2} \\V=\sqrt{(13.5)^2+(-6.42)^2}=14.9m/s

How we can see different colors by our eyes?
IrinaVladis [17]

I DID A Science PROJECT ON THIS >:)))

basically light travels into the eye to the retina located on the back of the eye. the retina is covered withe millions of light sensitive cells called Rods and cones. when these cells detect light they send signals to the brain that help detect color.

the color of an object is determined by the wavelengths of light that it reflects. it's determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to quantum laws.
