Color of third band of a coded resistor is Brown.
What is Resistance:
- Resistance is a measure of the opposition to current flow in an electrical circuit.
- Resistance is measured in ohms, omega (Ω)
The color code specify the resistance value, the tolerance, and sometimes the reliability or failure rate.
How to identify resistor's color codes:
- Look at the resistor so the group of 3 or 4 color bands are on the left side
- Read the color bands from left to right.
- Read the color on the last color band, which is farthest right.
- compare the colors to the resistance code table
Here,
the value of resistance is 2.3x10^2 Ω
R = 23x10^1 Ω
here power of 10 is 1
so, the color of third band of a color coded resistor will be related to number 1
Hence,
color of third band of a coded resistor is Brown.

You would need to connect a potential difference across a resistor in parallel
Answer:
a)0.674 kg b) 2.2 s c) 0.9 m/s²
Explanation:
The amplitude of the ball (xo) = 11.0cm, half way between its equilibrium point its maximum displacement x = 11 cm / 2 = 5.5 cm = 5.5 / 100 in meters = 0.055 meters, speed at this point = 27.2 cm /s = (27.2 / 100) in m/s = 0.272 m/s,
spring constant K = 5.5 N/m
a) The mass of the ball (m) can be calculated using the formula below
v =√ (x²o - x²)K/m
make m subject of the formula
v² = (xo² - x²) K/m
m = K ( xo² - x²) / v²
m = 0.674kg
b) The period of the oscillation can be calculated by the following formula
T = 2π√ (m /K)
substitute the values into the formula
T = 2 × 3.142 × √ (0.674/ 5.5) = 2.2s
c) The maximum acceleration of the ball which occurs at the maximum displacement of the ball can be calculated by the following formula
a = K / m × x ( maximum displacement of the body) = 5.5 / 0.674 × 0.11 = 0.9 m/s²
Answer:
1:a
2:c
3:f
4:d
5:f or e
6:d
Explanation:
Hope it helps! also if im wrong sorry. but i already learned this so yeah have a nice day!
The true statement about ligand gated sodium ion channels in neurons are open in response to chemical messenger and hyperpolarize the membrane.
<h3>What are ligand gated sodium ion channels?</h3>
Ligand gated sodium ion channels are the channels present in the neurons. Ion moves through this channel inside the cell or outside the cell.
Thus, the correct option is a) Open in response to chemical messenger and depolarize the membrane.
