Answer:
10.1 m /s²
Explanation:
Let m₁ be the mass of the helium gas inside balloon. Mass of air displaced is m₂
m₁ = volume x density
= 4/3 x 3.14 x 5³ x .179
= 93.67 kg
mass of displaced air
= 4/3 x 3.14 x 5³ x 1.16
= 607.06 kg
Net buoyant force in upward direction
(607.06 - 93.67 ) x g
= 5031.22 N
weight of people and gondola
= (2 x 70 + 64 ) x 9.8
= 1999.2 N
Net force in upward direction
= 5031.22 - 1999.2
= 3032.02 N
Acceleration produced
= 3032.02 / total mass
= 3032.02 / ( 93.67 +204 )
= 3032.02 / 297.67
= 10.1 m /s²
Answer:
It would be the 10 lb ball.
Explanation:
The more that an object weighs, the more force that is needed to accelerate it.

Explanation:
From the question we are told that
The refractive index of the core is
The refractive index of the cladding is
Generally according to Snell's law
Where is the largest angle a largest angle a ray will make with respect to the interface of the fiber and experience total internal reflection
Given from the question the the largest angle is 5°
Generally the refraction index of the cladding is mathematically represented as
