Your car's 30.0 W headlight and 2.50 kW starter are ordinarily connected in parallel in a 12.0 V system. What power (in W) would

Tatiana [17]

Answer:

<h3>The power of headlight in series connection is 29.64 W</h3>

Explanation:

Given :

Power of headlight $P_{1} = 30$ W

Power of starter $P_{2} = 2500$ W

Voltage of headlight and starter $V = 12$ V

From equation of power,

$P = \frac{V^{2} }{R}$

$R = \frac{V^{2} }{P}$

For finding the resistance of headlight and starter,

⇒ For headlight,

$R_{1} = \frac{144}{30} = 4.8$ Ω

⇒ For starter,

$R_{2} = \frac{144}{2500} = 0.057$ Ω

Since equivalent resistance,

$R_{eq} = R_{1} + R_{2} + ........$

$R_{eq} = 4.8 +0.057 = 4.857$ Ω

So power in series is given by,

$P_{s } = \frac{V^{2} }{R_{eq} } = \frac{144}{4.857}$

$P_{s } = 29.64$ W

When you rub a glass rod with a piece of silk, the glass rod becomes positively charged?

Lynna [10]

Glass loses electrons easily and silk takes them. Because electrons are negatively charged, the glass rod becomes positive and the silk becomes negative.

If the torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 41 N · m, what minimum f

Marina86 [1]

We have that the Force is mathematically given as

F=170.833N

<h3></h3><h3>Force </h3>

Question Parameters:

The torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 41 N · m,
the end of a 24 cm-long wrench to <em>loosen </em>the nut

Generally the equation for the Force is mathematically given as

$F=\frac{T}{d}$

Therefore

F=41/0.24

F=170.833N
