The current in a circuit is tripled by connecting a 580 resistor in parallel with the resistance of the circuit. Determine the r

const2013 [10]

Answer:

1160 ohm

Explanation:

We are given that

R'=580 ohm

Current=3 I

We have to find the resistance of the circuit.

Let R be the resistance of circuit.

In parallel

$\frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}$

Using the formula

$\frac{1}{R_{eq}}=\frac{1}{580}+\frac{1}{R}=\frac{580+R}{580R}$

$R_{eq}=\frac{580R}{580+R}$

In parallel combination,Potential difference across each resistance remains same.

$V=IR$

Using the formula

$IR=3IR_{eq}$

$IR=3I\times \frac{580R}{580+R}$

$580+R=3\times 580=1740$

$R=1740-580=1160\Omega$

The honda insight, a hybrid electric vehicle, has an u.s. environmental protection agency (epa) gas mileage rating of 57 mi/gal

sergiy2304 [10]

Convert mL to gallons as follows:

355 mL = 0.355 L
0.355 L * (1 gal/3.785 L) = 0.0938 gallons

The equivalent km covered would be

57miles/gal * 0.0938 gal * (1.61 km/ 1 mile) = 8.61 kilometers

I hope I was able to help you. Have a good day!

A ball is thrown upward at time t=0 from the ground with an initial velocity of 4 m/s (~ 9 mph). Assume that g = 10 m/s^2. What

aleksandrvk [35]

Answer:

The greatest height reached by the ball is 0.8 m.

Explanation:

Given that,

Initial velocity = 4 m/s

We need to calculate the greatest height reached by the ball

Using equation of motion

$v^2=u^2+2gh$

Where, v = final velocity

u = initial velocity

g = acceleration due to gravity

Put the value in the equation

$0=4^2+2\times(-10)\times h$

$h =\dfrac{16}{20}$

$h =0.8\ m$

Hence, The greatest height reached by the ball is 0.8 m.
