Answer:
1. 21.66 Ohms
2. 3.38 A
3. 6.7 V
Explanation:
1. Req = 6+2 = 8 Ohms (2 and 6 are in a series circuit)
Req = 1/8 +1/4 = 3/8 = 8/3 = 2.66 Ohms (8 and 4 are parallel, so we will add them using this equation)
Req = 2.66 + 1 + 9 + 3 + 6 = 21.66 Ohms
2. I = V/R = 9/2.66 = 3.38 A (In a series circuit, the current is the same across the resistors, so we will add them and divided them by 9 volts)
3. V = IR = 3.38 x 2 = 6.7 V (In a series circuit, the voltage is different, so each resistor will have a different voltage.)
I hope this helps. I am not an expert in physics but its ok :)

The answer is A). Moving from A to C the temperature and the kinetic energy increases.
24-15=9 m/s slower in 12 seconds. So 9/12 m/s² slower. Therefore the acceleration is -0,75 m/s²
Light travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and cameras detect light.
Answer:
With the exception of natural gas fossil fuel energies have seen an overall decrease since year 2000.
Explanation:
Just observe the graph
The Fossil fuels include-Petroleum ,coal and natural gases.
- The graph of these goes fastly up during 20th century but ,then it stabled at the peak then has not shown any solid increase .
- Observe other energy sources graph ,nuclear energy etc have shown quite speedy increase .
Option C is correct
