11. From this lab we can conclude that a) the heat transferred when objects are rubbed together creates an energy that can cause
objects to move towards or away from each other. b) objects such as balloons and sweaters have a natural affinity towards each other. They will attract each other whether they are rubbed together or not. c) charges exert forces on other charges. do) charges do not exert forces on other charges.
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material so this causes one object to become positively charged and the other object is negatively charged so they will attract each other not repel each other. Charges exert forces on other charges i.e. opposite charges attract each other whereas similar charges repel each other so in both cases force are exerted on one another.
The jetliner is traveling against the wind. The net speed of the jetliner is 590 mph - 36 mph = 554 mph The time it takes for the jetliner to arrive at the destination is 1850 miles / 554 mph = 3.34 hours
