Folded mountains occur when the rocks push against each other.
Complete Question
A toroidal solenoid has 590 turns, cross-sectional area 6.20 cm^2 , and mean radius 5.00 cm .
Part A. Calculate the coil's self-inductance.
Part B. If the current decreases uniformly from 5.00 A to 2.00 A in 3.00 ms, calculate the self-induced emf in the coil.
Part C. The current is directed from terminal a of the coil to terminal b. Is the direction of the induced emf from a to b or from b to a?
Answer:
Part A
Part B
Part C
From terminal a to terminal b
Explanation:
From the question we are told that
The number of turns is
The cross-sectional area is
The radius is
Generally the coils self -inductance is mathematically represented as
Where is the permeability of free space with value
substituting values
Considering the Part B
Initial current is
Current at time t is
The time taken is
The self-induced emf is mathematically evaluated as
=>
substituting values
The direction of the induced emf is from a to b because according to Lenz's law the induced emf moves in the same direction as the current
To develop this problem we will use the concepts related to Speed in a string that is governed by Tension (T) and linear density (µ)
Our values are given as:
Replacing we have that the velocity is
From the theory of wave propagation the average power wave is given as
Where,
A = Amplitude
Angular velocity
Replacing,
Therefore the amplitude of the wave should be 0.0165m

Answer:
The wavelength in nanometers is 849.81 nanometers (nm)
Explanation:
Here is the complete question:
A laser technician measures the wavelength of light from a new semiconductor laser. The wavelength is 8.4981 × 10⁻⁷m . What is the wavelength in nanometers. Write your answer as a decimal.
Explanation:
The given wavelength is 8.4981 × 10⁻⁷m.
To determine the wavelength in nanometers, we will convert the given wavelength from meters (m) to nanometers (nm).
1 nanometer = 1 × 10⁻⁹ meters
∴ 10⁻⁹ meters = 1 nanometer
To convert 8.4981 × 10⁻⁷m to nanometer (nm):
If 10⁻⁹ meters (m) = 1 nanometer (nm)
Then, 8.4981 × 10⁻⁷m = (8.4981 × 10⁻⁷m × 1 nm) / 10⁻⁹ m
8.4981 × 10⁻⁷m = 8.4981 × 10⁻⁷ × 10⁹ nm
= 8.4981 × 10² nm
= 849.81 nm
Hence, the wavelength in nanometers is 849.81 nm
