A chair of weight 95.0N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 3
AlladinOne [14]

Answer:

Answer:

118.4 N

Explanation:

weight of chair, mg = 95 N

Push, F = 39 N

Ф = 37 ° below x axis

Let n be the normal force.

So, by using the diagram and resolve the components of Force F.

n = mg + F SinФ

n = 95 + 39 Sin 37°

n = 95 + 39 x 0.6

n = 118.4 N

Consider a series LRC-circuit in which C-120.0 uF. When driven at a frequency w = 200.0 rad s-1 the com ples impedance is given
Lina20 [59]

Answer:

(a). (i). The reactants are X_{L} =31.66\ \Omega .

(II). The inductance of the circuit is 0.1583 Henry.

(b). The resonant angular frequency is 229.4 rad/s.

Explanation:

Given that,

Capacitor = 120.0 μC

Frequency = 200.0 rad/s

Impedance = 100.0 -10j

(I). We need to calculate the X_{C}

X_{C}=\dfrac{1}{C\times\omega}

Put the value into the formula

X_{C}=\dfrac{1}{120\times10^{-6}\times200}

X_{C}=41.66\ \Omega

(II). We know that,

Formula of impedance is

Z=\sqrt{R^2+X_{L}^2+X_{C}^2}...(I)

Given equation of impedance is

Z=(100-10j)...(II)

On Comparing of equation (I) and (II)

R = 100

X_{L}-X_{C}=-10

Now, put the value of  X_{C}

X_{L=41.66-10

X_{L}=31.66\ \Omega

We need to calculate the inductance

Using formula of inductance

X_{L}=\omega\times L

Put the value into the formula

L=\dfrac{X_{L}}{\omega}

L=\dfrac{31.66}{200}

L=0.1583\ Henry

(b). We need to calculate the resonant angular frequency

Using formula of the resonant angular frequency

angular\ frequency =\dfrac{1}{\sqrt{L\times C}}

angular\ frequency =\dfrac{1}{\sqrt{0.1583\times120\times10^{-6}}}

angular\ frequency =229.4\ rad/s

Hence, (a). (i). The reactants are X_{L} =31.66\ \Omega .

(II). The inductance of the circuit is 0.1583 Henry.

(b). The resonant angular frequency is 229.4 rad/s.

Which are characteristics of a gas? (Select all that apply.)It cannot move.It fills the container it is in.It can be compressed.
Aleonysh [2.5K]

Answer:  no definite shape (takes the shape of its container)

no definite volume.

particles move in random motion with little or no attraction to each other.

highly compressible.

Explanation:

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
