Answer:
What is a Pure Substance?
Explanation:
It is something which cannot be divided into parts by physical means, as it's all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically).
Answer:
an element
Explanation:
Elements are not able to be separated, but everything else can, whether that be physically or chemically.
Not my work i looked it up, so no copy write please rate!
Calculate the current in the 200.-ohm resistor.
Answer:
current in 200ohm resistor = 0.05A
Explanation:
for current in 200 ohm resistor,
let 'I2' and 'R2' be current and resistance in 200 ohm resistor,
potential difference remains same thorughout the circuit because they are connected in parallel,
we have,
V=10V
R2=200 ohm
I2=?
then by ohm's law,
V=I2*R2
10=I2*200
I2=0.05A
The power dissipated by the 100-ohm resistor is 400 watts. The current in the 200-ohm resistor is 0.05 Amps.
To determine the power dissipated by the 100-ohm resistor, we can use the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance. Since the current is the same throughout a parallel circuit, the current flowing through the 100-ohm resistor is the same as the total current in the circuit. Using the formula P = I^2 * R, we can calculate the power dissipated by the 100-ohm resistor as P = (2.00 A)^2 * 100 ohms = 400 watts.
To calculate the current in the 200-ohm resistor, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage supplied by the battery is 10.0 volts. Using Ohm's Law, we can calculate the current in the 200-ohm resistor as I = V / R = 10.0 V / 200 ohms = 0.05 Amps.
