Manuel and Sandy were partners. Sandy held the accelerometer in her hands while Manuel watched the water line. Throughout Sandys walk,
the water line remained level. What does that tell the students about
Sandy's motion?
Sandy's velocity changed when she slowed down or
sped up.
A)
Sandy's speed might have changed but her direction
B) did not.
Sandy must not have been moving if the water line
remained level
Sandy's velocity is constant: her speed and direction
did not change.
D)

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
