2. A 15.0 N force is used to hold a mass on a string at an angle of 32° from the vertical, as in the

castortr0y [4]

Answer: 2.9kg

let mass be=m ; F=15N; Sin(theta)=32°;g =9.8kgm/s^2.

represent the mass. By resolving forces, we have:

F=mgSin(theta)

15N=mgSin(32°)

m=15N/g×Sin(32°)

m=15N/9.8m/s^2÷Sin(32°)

=2.888kg2.888

≈2.9kg

A generator connected to an RLC circuit has an rms voltage of 140 V and an rms current of 31 mA. Part A

vredina [299]

Answer:

53.06 ohm

Explanation:

We have given the rms voltage V =140 V

And the rms current i=31 mA

So the impedance $Z=\frac{V}{i}=\frac{140}{3\times 10^{-3}}=46.666kohm$

Resistance is given as R = 3 kohm

And capacitive reactance $X_C=6.5kohm$

We know that $Z=\sqrt{R^2+(X_L-X_C)^2}$

$46.666=\sqrt{3^2+(X_L-6.5)^2}$

Squaring both side $2177.1556=9+(X_L-6.5)^2$

$(X_L-6.5)^2=2168.155$

$(X_L-6.5)=46.5634$

$X_L=53.063ohm$
