5 0

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

Use the following study to answer the following question: A researcher applies varying amounts of fertilizer (0, 2, 4, 8, 10 uni

Ksenya-84 [330]

I believe the answer is the weight of each tomato.

This is because the weight of each tomato depends on the amount of fertilizer (the independent variable/the thing being changed) added to each plant.

Which statement describes the moment magnitude scale? A. It measures only small earthquakes. B. It collects data using a seismog

Verdich [7]

Answer:

The moment magnitude scale is a scale that rates earthquakes by estimating the total energy released by an earthquake . Estimating the total amount of energy released, enables comparison of earthquakes more accurately.

This scale can be used to rate earthquakes of all sizes, near or far. The following statements describe the moment magnitude scale:

B. It collects data using a seismograph.

D. It estimates the total energy released from an earthquake.

E. It determines the amount of damage caused by an earthquake.
