Three days,
1 1/4 = 5/4
1/2= 2/4
2/4+1/4= 3/4 the first day
5/4-3/4= 2/4
2/4 = 1/4 and 1/4 = two days
the first day+ two days= 3 days
The magnitude of the magnetic field in the central area inside the solenoid, in T is 0.0267 T
<h3>Magnetic field inside solenoid</h3>
The magnetic field inside the central area of the solenoid is given by B = μ₀ni where
- μ₀ = permeability of free space = 4π × 10⁻⁷ Tm/A,
- n = number of turns per unit length = 3,170 turns/m and
- i = current in solenoid = 6.7 A
Since B = μ₀ni
Substituting the values of the variables into the equation, we have
B = μ₀ni
B = 4π × 10⁻⁷ Tm/A × 3,170 turns/m × 6.7 A
B = 4π × 10⁻⁷ Tm/A × 21239 A-turns/m
B = 84956π × 10⁻⁷ T
B = 266897.15 × 10⁻⁷ T
B = 0.026689715 T
B ≅ 0.0267 T
So, the magnitude of the magnetic field in the central area inside the solenoid, in T is 0.0267 T

Answer:
The correct answer is option A. 90°
Step-by-step explanation:
<u>Points to remember</u>
Measure of angles on the semicircle is 90°
From the figure we can see a semicircle and a triangle inscribes on it.
<u>To find the measure of <XYZ</u>
Here <XYZ is on the semicircle that is angle XYZ is a right angle.
Therefore m<XYZ = 90°
The correct answer is option A. 90°
Answer:
$225
Step-by-step explanation:
The area to be fenced in is 20 ft by 45 ft, or 900 ft^2. But "25 per foot based on the area" is illogical. Please ensure that you have copied this problem down accurately, and be sure to provide units of measurement: did you mean $25 per square foot, or per foot, or what?
The fencing cost is usually dependent on the unit cost and the length of the yard perimeter. The perimeter is P = 2L + 2W, which here is P = 2(45 ft) + 2(20 ft), or 130 ft. If the fencing is 25 cents per foot, $130 ft of fencing would come to $32.50.
