Ben claims that 12 is a factor of 24.how can you check whether he is correct?

1 answer:

8 0

Divide the 24 by Ben's 12 .

If his 12 is a factor, then the division will come out even,
and the answer will be a whole number.

A). 6 x 4 = 24

B). 5 x 9 = 45

C). 3 x 8 = 24

D). 6 x 9 = 54

An alternating current E(t)=120sin(12t) has been running through a simple circuit for a long time. The circuit has an inductance

Dvinal [7]

Answer:

14.488 amperes

Step-by-step explanation:

The amplitude I of the current is given by

$\large I=\displaystyle\frac{E_m}{Z}$

where

$\large E_m$ = amplitude of the energy source E(t).

Z = Total impedance.

The amplitude of the energy source is 120, the maximum value of E(t)

The total impedance is given by

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

where

R= Resistance

L = Inductance

C = Capacitance

w = Angular frequency

$\large X_L=wL$ = inductive reactance

$\large X_C=\displaystyle\frac{1}{wC}$ = capacitive reactance

As E(t) = 120sin(12t), the angular frequency w=12

$\large X_L=12*0.37=4.44\\\\X_C=1/(12*7)=0.012$

and

$\large Z=\sqrt{7^2+(4.44-0.012)^2}=8.283$

Finally

$\large I=\displaystyle\frac{E_m}{Z}=\frac{120}{8.283}=14.488\;amperes$
