Answer:
Explanation:
ball's weight = mg = .5 x 9.8 = 4.9 N.
If T₁ be tension at the top , centripetal force provided at the top
= mg + T₁ = 4.9 + T₁
4.9 + T₁ = m v² / r , v = velocity at the top , r = radius of circular path = 1.02 m
4.9 + T₁ = .5 x 4² / 1.02
4.9 + T₁ = .5 x 4² / 1.02
= T₁ = 7.843 - 4.9 = 2.943 N
If T₂ be tension at the bottom , centripetal force provided at the bottom
= T₂ - mg = T₂ - 4.9
T₂ - 4.9 = m v² / r , v = velocity at the bottom , r = radius of circular path = 1.02 m
T₂ - 4.9= .5 x 7.5² / 1.02
T₂ - 4.9 = .5 x 7.5² / 1.02
T₂ = 32.47 N
Distance of first instance = speed * Time
= 60 * 3 = 180 miles
Distance of second instance = speed * Time
= 24 * 5 = 120 miles
So, Total Distance = 180 + 120 = 300 miles
In short, Your Answer would be 300 miles
Hope this helps!

5500
Explanation:
I cant explain it but when i asked my teacher thats what he told me
When the incident light is yellow the width of the central band greater. Single-wavelength light sources are known as monochromatic lights, where mono stands for one and chroma for color. Monochromatic lights are defined as visible light that falls inside a specific range of wavelengths. It has a wavelength that falls within a constrained wavelength range.
A laser beam is the ideal illustration of monochromatic light. A monochromatic light beam produced by a single atomic transition with a particular single wavelength is what makes up a laser. A color scheme that consists solely of different shades of one color is referred to as monochromatic.
