7. The graph above shows how the speed of a book changes as it slides across a table in a
straight line. Over what time interval is the
net force on the book in the opposite direc-
tion of the book's motion?
A. O s to 0.5 S
B. 0.5 s to 2.4 s
C. O s to 2.4 s
D. 2 s to 2.4 s

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
