Suppose that two boys pull a sled with forces of 2.0 x 104 N at a 15° angle to the left of the center of the sled, and 1.8 x 104 N at an angle of 25° to the right of the center of the sled, respectively.

If the sled does not move, what is the other force that must be acting on the sled?

a. 2.1 x 104 N at 260°
b. 2.1 x 104 N at 290°
c. 3.6 x 104 N at 266°
d. 3.6 x 104 N at 282°

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

this would be about 43%

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
