Answer:

The original or accepted value for the percent by mass of water in a hydrate = 36%

Percen by mass of water in the hydrate determined by the student

in the laboratory = 37.8%

So the difference between the actual and the percent by mass in water determined by student = (37.8 - 36.0)%

            = 1.8%

So the percentage of error made by the student = (1.8/36) * 100 percent

                                                                            = (18/360) * 100 percent

                                                                            = ( 1/20) * 100 percent

                                                                             = 5 percent

So the student makes an error of 5%. Option "1" is the correct option.

Two pucks collide with each other. after the collision they do not stick together. is kinetic energy conserved in the collision?
miv72 [106K]
Since they do not stick after collision hence collision is elastic. In elastic collision, both momentum and kinetic energy is conserved because in this type of collision, first body deforms but then quickly regains its former shape and transfers its kinetic energy to the second pluck.
So kinetic energy is conserved.
