C. The object is not in motion, ruling out A. We are not adding mass in any way, nor does adding heat to object increase its mass, therefore also ruling out B. Finally, we are not changing the object's position in such a way that gives it a higher ability to do work, ruling out D.

A capacitor is connected to an ac generator that has a frequency of 3.4 kHz and produces a voltage of 2.0 V. The current in the

garik1379 [7]

Answer:

$V_G=3.302857143V$

Explanation:

Let´s find the capacitor impedance:

$V=IZ_C$

Using the data provided:

$Z_C=\frac{V}{I}=\frac{2}{0.035}=57.14285714$ Ω

Now let´s find the capacitance:

$Z_C=\frac{1}{j2\pi fC }$

$C=\frac{1}{j2\pi fZ_C} =\frac{1}{j2\pi (3400)(57.14285714)}= 0.8191798542$ μF

We can calculate the capacitor impedance for the second case:

$Z_C=\frac{1}{j2\pi fC}=\frac{1}{j2\pi (5000)(0.8191798542X10^{-6}) }=38.85714285$ Ω

Finally we can calculate the voltage of the second generator:

$V_G=IZ_C=(0.085)(38.85714285)=3.302857143V$

If a 950 kg car has 30,400 J of kinetic energy, how fast is it moving?

abruzzese [7]

Hello

The kinetic energy K of a moving object is:
$K= \frac{1}{2} m v^2$
where m is the mass and v the velocity of the object.
Using this formula, we can calculate v for this problem:
$v= \sqrt{ \frac{2E}{m} }= \sqrt{ \frac{2\cdot30400~J}{950~Kg} } = 8~m/s$

olga2289 [7]

The correct answer is C) frequency.
In fact, the frequency is the number of wave crests (or pulses) per seconds. In our problem, the machine that produces the wave pulses two times per second, so this is exactly the frequency of the compression wave.
