a. use an appropriate tool to make the same observation
b. make a prediction from previous data
c. make an inference from other observations
d. avoid the use of mathematical equations in recording your observation

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Which phenomena are transmissions of light? refraction, polarization, and scattering polarization, scattering, and reflection reflection, refraction, and absorption scattering, absorption, and refraction

In general, the friction involved in sliding an object is the friction involved in rolling an object. less than greater than equal to
