if in series one lightbulb burns out the rest are unable to turn on.
In parallel a single light bulb burns out any other light bulbs are able to work.
Parallel is the best to use during holidays.
Step 1: Look in your book or online for the conical pendulum equation.
Step 2: Look at the drawing and see which angle is involved in the equation.
Answer: It's Angle #2 in your drawing.
Hello
1) First of all, since we know the radius of the wire (

), we can calculate its cross-sectional area

2) Then, we can calculate the current density J inside the wire. Since we know the current,

, and the area calculated at the previous step, we have

3) Finally, we can calculate the electric field E applied to the wire. Given the conductivity

of the aluminium, the electric field is given by
Answer:
The wavelength is 3500 nm.
Explanation:
d= 
n= 1
θ= 30°
λ= unknown
Solution:
d sinθ = nλ
λ = 
λ = 3500 nm
The problem is most likely that the commutator brushes bounces as the motor shaft rotates.
<h3>What is a DC motor?</h3>
This is referred to a device which converts direct current electrical energy into mechanical energy.
if the commutator brushes bounces as the motor shaft rotates over different materials, the ticking sound is heard.
