Asled is tied to a tree on a frictionless, snow-covered hill, as shown in fiqure (a). if the sled weighs 66.0 n, find the magnitude of the tension force t exerted by the rope on the sled and that of the normal force n exerted by the hill on the sled. t= n 1= getting started i i'm stuck exercise hints: use the values from practice it to you work this exercise. suppose a child of weight w climbs onto the sled. if the tension force is measured to be 60.5 n, find the weight of the child and the magnitude of the normal force acting on the sled.

you have to draw the persons position over there

chemical properties of thing

the device is called “ rocket engine”

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.
