12. Mare is throwing rocks off of a cliff down to the river below. She throws the rock with an initial velocity of 12.0 m/s at an angle of 45.0
degrees. If the rock is in the air for 5.00 seconds, how high is the cliff?

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
