Answer:
<h3>5 meter / sec.</h3><h3 />
Explanation:
speed = distance / time
= 15 meters / 3 seconds
= 5 meter / sec.
F=K*X,
F=M*a
M*a=K*X
2.5*9.81=K*0.0276
24.525=K*0.0276
24.525/0.0276=K
K= 888.6 N/m ---- force constant
assuming 2.5 refers to the new extension, just divide F/ 0.025
to get
981N/m
Answer:
I_2 = 0.146 A
Explanation:
The formula for current in an inductor is;
I_rms = V_rms/X_L
Where X_L is inductance wirh formula 2πfL
So, I_rms = V_rms/X_L
Applying this to the two generators, we have;
First generator;
I_1 = V_rms/(2π(f_1)L)
And I_2 = V_rms/(2π(f_2)L)
Thus, to find the current in the second generator, we divide eq 1 by eq 2;
So,
I_2/I_1 = [V_rms/(2π(f_2)L)]/[V_rms/(2π(f_1)L)]
Some values will cance out leaving us with;
I_2/I_1 = f_1/f_2
I_2 = I_1(f_1/f_2)
Plugging in the relevant values ;
I_2 = 0.56(1.2/4.6)
I_2 = 0.146 A
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.
