True or False: You walk across a carpet and accumulate a net negative charge on the soles of your shoes. When you touch your sis

ter with your finger and give her a small zap, the charge that accumulated on your finger is due to charging by contact.

Answer:

True

Explanation:

Charging by conduction occurs when a charged conductor comes in contact with an uncharged conductor, leading to the sharing of charges between both conductors. Contact charging leads to a sharing and distribution of the same type of charges on the two conductors.

In this case, your entire body is charged by the sole of your feet coming in contact with the charged carpet on the floor, leading to a charge buildup all over your body.

Answer:

Part 1: 0.3789

Part 2: 746 J

Part 3: 2.162 kW

Explanation:

Part 1:

Eff=  1-\frac{1223}{1969}

Eff= 0.378873 ≈ 0/3789

Part 2:

W= 0.3789(1969)

W= 746 J

Part 3:

Power=\frac{W}{t}

Power= \frac{746}{0.345}

Power= 2162.3188 Watts

2162.3188 W-----> 2.162 kW

which is heavier, a one ton box or a one metric ton box? How many pounds heavier is one than the other?
arsen [322]

-- 1 ton is defined as 2,000 pounds.
-- 1 metric ton (or tonne) is defined as 1,000 kilograms of mass.

On Earth,1,000 kilograms of mass weigh 2,204.6 pounds ... 204.6 pounds
more than 1 ton.

On, say, the moon, however, 1,000 kilograms of mass weigh
only 364.9 pounds ... about 18% of 1 ton.

A resistor with an unknown resistance is connected in parallel to a 13 Ω resistor. When both resistors are connected in parallel
larisa86 [58]

Answer:

R2 = 10.31Ω

Explanation:

For two resistors in parallel you have that the equivalent resistance is:

\frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}\\\\      (1)

R1 =  13 Ω

R2 = ?

The equivalent resistance of the circuit can also be calculated by using the Ohm's law:

I=\frac{V}{R_{eq}}\\\\R_{eq}=\frac{V}{I}            (2)

V: emf source voltage = 23 V

I: current = 4 A

You calculate the Req by using the equation (2):

R_{eq}=\frac{23V}{4A}=5.75\Omega

Now, you can calculate the unknown resistor R2 by using the equation (1):

\frac{1}{R_2}=\frac{1}{R_{eq}}-\frac{1}{R_1}\\\\R_2=\frac{R_{eq}R_1}{R_1-R_{eq}}\\\\R_2=\frac{(5.75\Omega)(13\Omega)}{13\Omega-5.75\Omega}=10.31\Omega

hence, the resistance of the unknown resistor is 10.31Ω
