Alight, inextensible cord passes over a light, frictionless pulley with a radius of 8.9 cm. it has a 19 kg mass on the left and a 2.6 kg mass on the right, both hanging freely. initially their center of masses are a vertical distance 3.8 m apart. the acceleration due to gravity is 9.8 m/s^2. at what rate are the two masses accelerating when they pass each other? answer in units of m/s^2. what is the tension in the cord when they pass each other? answer in units of n.

Answer

given,

m₁ = 19 kg

m₂ = 2.6 kg

radius = 8.9 cm

vertical distance = 3.8 m

acceleration due to gravity = 9.8 m/s²

a)

a = 7.24 m/s²

b) T = 2.6 × (9.8 + 7.24)

T = 44.30 N

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
