Oliga [24]3 years ago
4 0

Answer:

I) True,  II) False,  III) False,  IV) True    

Explanation:

In this exercise, it is asked to answer different statements, for this we will use the relationship between angular and linear velocity

           v = w r

let's review the claims

I) True. From the initial equation we see that the linear velocity depends on the radius

II) False. All points rotate with the same angular velocity

III) False. Linear velocity changes with radius

IV) True. The angular velocity of all points is the same

max2010maxim [7]

Answer:

c. 5cm \times 8cm

Explanation:

The dimensions 5cm\times 8cm have the highest cross-sectional area combination of 40cm^2.

-Resistance reduces with an increase in cross sectional area.

-Reason-Electrons have alarger area to flow through.

A 0.22 kg mass at the end of a spring oscillates 2.9 times per second with an amplitude of 0.13 m .
andre [41]

Answer:

2.3687599 m/s

0.91106 m/s

0.617213012 J

Explanation:

f = Frequency = 2.9\ Hz

A = Amplitude = 0.13 m

k = Spring constant

m = Mass of object = 0.22 kg

Angular velocity is given by

\omega=2\pi f\\\Rightarrow \omega=2\pi 2.9\\\Rightarrow \omega=18.22123\ rad/s

Velocity is given by

V=A\omega\\\Rightarrow V=0.13\times 18.22123\\\Rightarrow V=2.3687599\ m/s

Speed when it passes the equilibrium point is 2.3687599 m/s

Frequency is given by

f=\dfrac{1}{2\pi}\sqrt{\dfrac{k}{m}}\\\Rightarrow k=m4\pi^2f^2 \\\Rightarrow k=0.22\times 4\pi^2\times 2.9^2\\\Rightarrow k=73.04296\ N/m

x = Displacement = 0.12 m

In this system the energies are conserved

\dfrac{1}{2}kA^2=\dfrac{1}{2}mv^2+\dfrac{1}{2}kx^2\\\Rightarrow v=\sqrt{\dfrac{k(A^2-x^2)}{m}}\\\Rightarrow v=\sqrt{\dfrac{73.04296(0.13^2-0.12^2)}{0.22}}\\\Rightarrow v=0.91106\ m/s

The speed when it is 0.12 m from equilibrium is 0.91106 m/s

The energy in the system is given by

E=\dfrac{1}{2}kA^2\\\Rightarrow E=\dfrac{1}{2}\times 73.04296\times 0.13^2\\\Rightarrow E=0.617213012\ J

The total energy of the system is 0.617213012 J
