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

it becomes positively charged by charging it

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
