High-speed train pulls out of the lyons station and is accelerating uniformly to its cruising speed. inside one of the cars, a 3 n digital camera is hanging from the luggage compartment by a light, flexible str that makes a 12 angle with the vertical. what is the acceleration of the train? 3.06m/s 2.08m/s 5.00m/s 4.09m/s

b

Fnet = T  

Fx = m*ax  

Fy = m*ay  

Fy = T * cos12º = m * g  

T * 0.97 = 3 * 9.8  

T = 3*9.8/0.97  

= 30.057 N  

Fx = m*a = T * sin12º

Fx = 3 * a = 30.057 * 0.24  

a = (30.057*0.208)/3  

≈ 2.083 m/s²

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).

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
