What is the effective resistance of this dc circuit
Inessa05 [86]

You've managed somehow to post the mirror image of the circuit diagram, including the numbers and values of the resistors.  I'm curious to know how you did that.

The three resistors at the left end of the diagram are  3Ω ,  2Ω , and  1Ω  all in series.  They behave like a single resistor of  (3+2+1) = 6Ω .

That  6Ω  resistor is in parallel with the  2Ω  drawn vertically in the middle of the diagram.  That combination acts like a single resistor of  1.5Ω  in that position.

Finally, we have that  1.5Ω  resistor in series with  1Ω  and  4Ω  .  That series combination behaves like a single resistor of  <em>6.5Ω</em>  across the battery V.

Ostrovityanka [42]

Answer:

a. 0.5307 sec

b. 0.4458 m

c. =v_x=0.84\ m/s\ ,\ v_y=5.2\ m/s

Explanation:

Horizontal Motion

It describes the dynamics of an object thrown horizontally in free air. The initial horizontal velocity is maintained all the time since no horizontal forces are acting. The initial vertical velocity is zero at launch time, but it grows downwards powered by the acceleration of gravity.  

The object hits the ground at a distance x from the point of launching, after having traveled a vertical distance y_o, taking a time t to complete the travel. The formulas who relate the different magnitudes are

v_x=v_o

The horizontal velocity v_x is the same regardless of the elapsed  time

v_y=gt

x=v_ot

\displaystyle y=y_o-\frac{gt^2}{2}

The plate of apple pie left the counter at a speed  

v_o=0.84\ m/s

The counter is y_o=1.38\ m high.

a.

Knowing that

y_o=1.38\ m

We use this formula to compute t

\displaystyle y=y_o-\frac{gt^2}{2}

At the moment when the plate hits the floor y=0

\displaystyle 0=y_o-\frac{gt^2}{2}

\displaystyle y_o=\frac{gt^2}{2}

Solving for t

\displaystyle t=\sqrt{\frac{2y_o}{g}}

\displaystyle t=\sqrt{\frac{2(1.38)}{9.8}}

t=0.5307\ sec

b.

x=(0.84)(0.5307)

x=0.4458\ m

c.

v_x=0.84\ m/s

v_y=(9.8)(0.5307)

v_y=5.2\ m/s
