Circumference of the tire = (2 pi) x (radius)

                                     =  (2 pi) x (0.62 meter)

                                     =    3.9 meters

If the tire never slips or skids, then the speed of the vehicle is

             speed  =  (distance)  /  (time to cover the distance)

                       =  (5 x 3.9 meters)  /  1 second

                       =     19.48 meters/second   .

                    (about 43.6 miles per hour)  .

We can't say anything about the vehicle's velocity, because we have
no information about the direction in which it's heading.

WILL AWARD BEST ANSWER! find the current flowing across the 30 ohm resistor<br> i = _ a
Lelu [443]

0.143 A

Explanation:

The total resistance of the circuit is

r =  \frac{(40)(30)}{40 + 30}  +  \frac{(50)(20 + 10)}{50 + (20 + 10)}   \\ = 35.89 \: ohms

so the total current is

Itotal= V/R = 9V/35.89 ohms

= 0.25 A

To find the voltage drop across the 30-ohns resistor, use

V = Itotal × (combined resistance of 40 30)

= 0.25 A × 17.14 ohms = 4.285 volts

so the current through the 30-ohm resistor is

I = (voltage drop)/30-ohms

= (4.285 V)/(30 ohms)

= 0.143 A

The speed limit on some interstate highways is roughly 80 km/h. What is this in meters per second? How many miles per hour is th
sergey [27]

Answer:

1) Speed in m/s equals 22.22 m/s.

2) Speed in miles per hour equals 49.712 mph.

Explanation:

Since we know that in 1 kilometer there are 1000 meters and in 1 hour there are 3600 seconds hence we can write

80km/h=\frac{80\times 1000m}{3600s}=22.22m/s

Now we know that 1 mile equals 1.609 kilometer  hence we conclude that 1 kilometer equals \frac{1}{1.609}=0.6214mile

Hence

80km/h=\frac{80\times 0.6214miles}{1h}=49.712mph

A paper airplane is thrown westward at a rate of 6 m/s. The wind is blowing at 8 m/s towards the north. Which of the following d
Andrew [12]

since airplane is thrown towards west with speed 6 m/s

while air is blowing with speed 8 m/s towards north

so here the net speed of air plane will be the resultant of airplane speed and wind speed always

SO here we can say it would be a combination of vector along west with must be of length 6 m/s and other vector is towards north with is of length 8 m/s

so correct answer must be 1st option
