As shown in the diagram, a bead slides on a wire which is in a vertical plane (i. e. perhaps in the plane of your computer screen). Gravity acts in the -y direction (down). The bead starts at A and moves to the right with an initial velocity v. The wire is frictionless between A and D and also between F and G, but there is friction between D and F. For each statement select True, False, Greater than, Less than, Equal to, or Not enough information to tell.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

a.   mass number from atomic number

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

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.
