Answer:

The current through 9 \Omega is 0.297 A

Solution:

As per the question:

R_{5} = 5.0 \Omega

R_{9} = 9.0 \Omega

R_{4} = 5.0 \Omega

V = 6.0 V

Now, from the given circuit:

R_{5} and R_{9} are in parallel

Thus

\frac{1}{R_{eq}} = \frac{1}{R_{5}} + \frac{1}{R_{9}}

R_{eq} = \frac{R_{5}R_{9}}{R_{5} + R_{9}}

R_{eq} = \frac{5.0\times 9.0}{5.0 + 9.0} = 3.2143 \Omega

Now, the R_{eq} is in series with R_{4}:

R'_{eq} = R_{eq} + R_{4} = 3.2143 + 4.0 = 7.2413 \Omega

Now, to calculate the current through R_{9}:

V = I\times R'_{eq}

I = {6}{7.2143} = 0.8317 A

where

I = circuit current

Now,

Voltage across R_{eq}, V':

V' = I\times R_{eq}

V' = 0.8317\times 3.2143 = 2.6734 V

Now, current through R_{9}, I' :

I' = \frac{V'}{R_{9}}

I' = \frac{2.6734}{9.0} = 0.297 A

Two trains are headed towards each other on the same track unbeknownst to the engineers. One departs San Francisco. Its average
aalyn [17]

Answer:

7,166 hrs =430  minutes

Explanation:

Since both train are on the same track, going one towards the other, the relative speed is the addition of both, then the time they need to meet, and consistently crash, is the time that (65mph + 55 mph)=120mph need to travel the total distance of 860 miles, of course in this case one part is traveled by the first train and the rest by the other. Then to find the time we use a three rule

1 h --->120mi

X ---->860mi, then X=(860 mi* 1h)/120 mi = 43/6 hrs= 7,16666 hrs, turning this into minutes need that we notice 1h=60min, then 43/6 hrs *60 min/hrs = 430 minutes.
