1)B
The punk subculture appeared in the USA, the United Kingdom, Australia and South Africa in the mid-to-late-1970s, and has since undergone several developments.
2)___
The punk subculture is centred around listening to recording or live concerts of a loud, aggressive genre of rock music. Punk rock is a rock music genre that developed in the USA, the United Kingdom, and Australia. It is rooted in garage rock and other forms of what is now known as proto-punk music, usually shortened to punk. Most punk rock uses guitar and noisy drumming that are derived from 1960s garage rock.
3)___
Punks try to shock people with the highly theatrical use of clothing: ripped clothing is held together by safety pins or wrapped with tape; ordinary clothing is decorated with marker or with paint; a black basket liner becomes a dress, shirt or skirt; safely pins and razor blades are used as jewellery.
4)___
Some punks make their hair stand in spikes, cut it into Mohawks (a hairstyle which consists of shaving both sides of the head, leaving a strip of noticeably longer hair) or other dramatic shapes, often colouring it with vibrant, unnatural colours.
5)___
The punk subculture has developed a variety of dancing styles, which appear chaotic and violent.​

1. The ohmmeter is used to measure the value of resistance while it is connected in paralltl to the resistor.

2. The ammeter is connected in series while the current is being measured.

3. While the value of current in the circuit is measured, the ammeter should be connected in series.

1. Suppose the ammeter scale reads 1.9 amp, the voltmeter scale reads 2.4 V; how much is the value of resistance in the measured circuit?

R = U / I = 2.4 / 1.9 = 1.26 Ohm

2. Suppose the ohmmeter scale reads 75 ohms, the voltmeter scale reads 220 V; how much is the value of current in the measured circuit?

I = U / R = 220 / 75 = 2.9 A

3. Suppose that you have a series circuit consisting of three resistors and a voltage source. R1 = 0.18 ohm, R2= 1.15 ohms, R3 = 2 ohms, I=10 amp. Find the voltage drop across each resistor; find the value of voltage in the circuit.

U1 = R1 * I = 0.18 * 10 = 1.8 V  

U2 = R2 * I = 1.15 * 10 = 11.5 V

U3 = R3 * I = 2 * 10 = 20 V

Suppose R1 gets open. What does it result in? I = 0

4. Two resistors are connected in series. R1 = 7,000, R2= 2,200, I = 110 amp. Find the voltage drop across each resistor.

U1 = R1 * I = 7,000 * 110 = 770,000 V  

U2 = R2 * I = 2,200 * 110 = 242,000 V

Suppose no current passes through the circuit, what does it result from?

It results from the broken circuit.
