Scientists will study how earths magnetic field changes as distance from earth changes. satellites will be placed at different distances from earth and will be used to measure the strength of earths magnetic field. Q: which of the following is the independent variable in this experiment? A: magnetic field strength
B: distance from earth
C: size of satellite
D: mass of satellite
E: gravitational force of earth

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
