Vsevolod [243]

Answer:

A) $V_{rms}=8\sqrt{2} V$

Explanation:

Maximum voltage = $V_{max}=16 V$

Maximum voltage and rms voltage are related to each other by

$V_{max}=V_{rms} \times \sqrt{2} \\V_{rms}=\frac{V_{max}}{ \sqrt{2}}\\V_{rms}=\frac{16}{\sqrt{2}} \\V_{rms}=8\sqrt{2} V$

Is there supposed to be a slit at the top of your adams apple?

Consider the image above. Vi = the initial velocity and Vf = the final velocity. Is there acceleration? Explain your answer.

Law Incorporation [45]

D) Yes. Even though the initial and final velocities are the same, there is a change in direction for the ball.
Acceleration (a) = change in velocity (v) over time (t), let's consider moving right is (+) and moving left is (-)
a = (vf - vi)/t = (-5 - +5)/t
a = (-10)/t
So even though the number looks the same from vi to vf, there actually is a negative acceleration of 10m/s/s.

The simple pendulum concept and rotational kinematics relationships allow finding the result for the velocity relationship

The shortest pendulum (w₁) has more speed than the longest pendulum (w₂)

w₁ = $\sqrt{2}$ w₂

The simple harmonic movement is a periodic movement where the restoring force is proportional to the elongation, in the case of the simple pendulum it is fulfilled for angles less than 10º. The expression for motion is

θ = θ₀ cos ωt

ω² = g / l

the angular velocity is defined by

w = $\frac{d \theta}{dt}$

w = - θ₀ ω sin ωt

Where θ₀ is the initial angle or amplitude, w is the angular velocity, t the time, g the acceleration of gravity and l the length of the pendulum

Let's find the angular velocity for each pendulum

ω ₁ = $\sqrt{ \frac{g}{l_1} }$

Indicate that the second pendulum length is

l₂ = 2 l₁

ω₂ = $\sqrt{\frac{g}{2l_1} }$

the pendulum speed is maximum at the lowest point of the trajectory that occurs when the sine function has its maximum value

w = θ₀ω

Suppose that the two pendulums are released with the same initial angle

Pendulum 1

w₁ = θ₀ $\sqrt{\frac{g}{l_1} }$

Pendulum 2

w₂ = θ₀ $\sqrt{\frac{g}{2l_1} }$

We look for the relationship between the two speeds

$\frac{w_1}{w_2} = \sqrt{2}$

In conclusion, using the simple pendulum concept and the rotational kinematics relations we can find the result for the velocity relation

The shortest pendulum (w₁) has more speed than the longest pendulum (w₂)

w₁ = √2 w₂

Discuss the difference between waveform graphs and vibration graphs

Kitty [74]

Difference exists mainly in the label for x axis.

Explanation:

Shapes of waveform and vibration graphs are same.
Vibration graphs shows the particle at a single location in the path of the wave when time passes.
Waveform graphs shows the particle at multiple locations at a single moment of time.
