Given Information:
Current = I = 61 A
Magnetic field = B = 1.30x10⁻⁴
Required Information:
Radius of wire = r = ?
Answer:
r = 0.093 meters
Step-by-step explanation:
Biot-Savart Law is given by
B = μ₀I/2πr
Where μ₀ is the permeability of free space and it is basically a measure of resistance in the formation of magnetic field.
I is the current flowing through the wire and B is the magnitude of the magnetic field produced.
Re-arranging the above equation to find out the radius of the loop
r = μ₀I/2πB
r = 4πx10⁻⁷*61/2π*1.30x10⁻⁴
r = 0.093 m
Hence, the radius of the loop wire is 0.093 meters.
#16
If we put a resistor in circuit it will slow the speed of current
Let's check ohms law
- So if resistance is more current is less
#17
Again use ohms law
- Voltage must be increased
Answer: Wind follows a pattern because the Earth is spinning in one motion. If we were spinning in one way then another we would have one day go by then the spinning cycle would change and we would have to go through that day all over again, it would not be logical because then we would be in the same season as well, we would be in one season for the rest of our lives until we died.
I don't know if this was helpfull or not but I hope it was somewhat close to helpful? If it is not then please do not report this, I am sorry if this was the least bit helpful.
HAVE A NICE DAY! :)
Answer: 690 W
Explanation:
A day has 24 hours, so a month has 24 × 30 = 720 hs
In a month whe spent a total of $60. 00, so per hour whe were spending
$ per hour
We know the cost of one is so dividing the money spent in an hour among this value we get:
This power delivered is constant, so every moment it is
The wavelength is 1.4 m for the wave with frequency of 250 Hz and speed is 350 m/s.
Answer:
Explanation:
Wavelength is the measure of distance between two consecutive crests or troughs. So it is the distance upto which every particle in a wave can move freely without any collision. So this distance can be found by finding the ratio of speed of wave to the frequency of wave. Thus, it is known that wavelength is inversely proportional to frequency. This is because, as the wavelength will be less, so the number of complete cycles in a given time interval will increase and vice versa.
Wavelength = Speed/Frequency
As the speed of wave is given as 350 m/s and the frequency is given as 250 Hz, the wavelength is as follows.
Wavelength = 350/250 = 1.4 m
So the wavelength is 1.4 m for the wave with frequency of 250 Hz and speed is 350 m/s.
