Question

6) A coil of wire with an area of 0.3 m2 consisting of 7 loops experiences a perpendicular magnetic filed that is 0.5 Teslas. What is the total magnetic flux through the loops? A=0.3m2 10.00 Wb N=7 looks 10.15 Wb B=0:57 I = NBA 7X0.58 0.3 10.32 Wb 1.05 Wb = 1.05 Wb be doubled & eight will become 7) Orange light has a wavelength of 600 nm. If I halve the frequency, what is true about the new light? Ao frequency is halved, It is now ultraviolet light wavelength will It's still orange but the lightwave travels slower It's still orange but the lightwave travels faster si infrared It's now infrared light 8) A mirror produces an image with a magnification of +5. Describe the location, size, and orientation of the image produced. Circle one from each pair of answers Same side as object opposite side as object m= hid Upright/ Inverted ho Real / Virtual Enlarged Reduced di negative and larger than do 9) In the Young's Double-Slit experiment, if we double the distance between the slits, what happens to the distance between the first and second maxima? The distance is doubled distance between first and The distance increases, but is not doubled The distance increases, but is not halved do hi ho tpringer -width WED The distance is halved as a doubles, the distance i halved 10) Two, 5-Ohm resisters, in series, are attached to a 12V battery. If you increase the resistance of the first resistor (R1), what happens to the current through the second (R2)? The current through R2 increases and is now greater than the current through R1 The current through R2 decreases and is now less than the current through R1 The current through R2 increases and is the same as the current through R1 The current through R2 decreases and is the same as the current through R1 Since the resistors in series, the The berth of net inca them will be the resistance R1 and current through Rider the does with R2. Thus, RI. R2 through as the current de tot through current through OM thus NE the current

Answer 1

Use the area, magnetic field and number of loops to find the magnetic flux using equation of flux through an area in a magnetic field.

6 6 11 NBA = (7)05T0-31) 1.05 wb = 7) now infoared Since the frequency is lowered it's light 8) Only concave mimor can produce image larger than object di do 5 m di -5 do { do is positive. So, di co So, image is formed 0 opposite side as object as di so Upright m > 0 111) Virtual di co Enlarged as m=5>
