What is the main difference between speed and velocity?

How well does the extrapolated value (the slope of the trend line) agree with the accepted value of free-fall acceleration (g = 9.8 m/s2)?

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
