Mr. Mullenmeister is photocopying lab sheets for his first-period class when the toner light on the onA particle of toner carrying a charge of the copying machine experiences an electric field of 1.2 * 10 ^ 6 * N / C as it's pulled toward the paper. What is the electric force acting on the toner particle? F=4.5=(40*10^ C)(1.2*106N/C)=4.8*10^ .5

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

Quantum mechanics applies to subatomic, atomic, nanometer-size, and micrometer-size systems. nanometer, micrometer, and kilometer-size systems. atomic, nanometer-size, and micrometer-size systems. subatomic, atomic, and nanometer-size systems.

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
