A picture of a rocket. There is a free body diagram to the right of the rocket with 2 forces. The force upward is labeled F Subscript gases Baseline = 9,452 N. The second vector is pointing down, labeled F Subscript rocket Baseline = negative 9,452 N. Both vectors are the same length. Based on the free-body diagram, the net force acting on this firework is N.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
