The comet which is violent and large scale, causing sudden and violent upheaval is known as "Cataclysmic Comet"
Hope this helps!
In order for Ren who runs a harmburger stand and needed to clean up a season's worth of grease buildup, the cleaning product that he should look for that can handle a layer of grease would be those caustic chemicals. These caustic chemicals <span>can be applied to break down the grease. When these grease are broken down, hot water can be applied to rinse it. These chemicals should be allowed to dwell on the surface of grease for a period of time to soften the grease buildup. Hope this answer helps.</span>
Answer:
Explanation:
wavelength of sound = velocity / frequency
= 340 / 780
= .4359 m
Let the observer be at equal distance d from in phase source .
let it moves by distance x for destructive interference .
path difference from source
= d + x - (d - x )
= 2x
for destructive interference
path difference = wave length / 2
2x = .4359 / 2 m
x = .4359 / 4
= .108975 m
10.9 cm
so observer must move by distance 10.9 cm towards on of the centers.
