Answer:
You get up-to-date readings
Explanation:
Answer:
the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
Explanation:
Given that:
The area vector of a square loop has 5 numbers of turns i.e n = 5
each with side length = 0.2 m
Current I = 2 A
uniform magnetic field = 50.0 T
Now; the magnitude of the total magnetic field B is calculated as :
B = IA
where;
I = current
A = area ( n × l²)
B = I ( n × l²)
B = 2 × 5 × 0.2²
B = 0.4 Am²
The direction of the magnetic moment is antiparallel to the area vector;
Hence ; the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
C. an ore. Like iron ore and gold oe. something deep in the Earth that can be mind and brought up.
Don't look now, but the question GIVES you the formula to use, and it GIVES you the numbers to plug into the formula.
The formula to use to find the distance covered by the sound is
<em>Speed = (distance) / (time)</em>
They also give you:
speed = 330 m/s
time = 0.40 second
Stuff the numbers into the formula:
330 m/s = (Distance) / (0.40 second)
Multiply each side by (0.40 second), and you get:
(330 m/s) / (0.4 second) = Distance
<em>825 meters = Distance</em>
At the same temperature . . .
<em> Fahrenheit reading = (1.8 times Celsius reading) + 32</em> .
F = (1.8 x 232) + 32
F = 417.6 + 32
<em>F = 449.6°</em>
