Two in-phase sources of waves are separated by a distance of 4.00m. these sources produce identical waves that have a wave length of 5.00m. on the line between them, there are two places at which the same type of interference occurs. 3) which type of interference occurs twice? constructive destructive 4) at what location from one of the sources does this interference occur? 0.5m and 3.5m 0.75m and 3.25m 1.5m and 2.5m 5) at what location from one of the sources does the other type of interference occur? 0.5m 1.0m 1.5m 2.0m a slit of width 4.30x10-5m is located 1.32m from a flat screen. light of wavelength 635nm is shining on the slit. 6) what is the width of the central bright fringe? .025m .039m .053m .067m

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

15: 24

62.5%

step-by-step explanation:

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
