Harry and Ron are arguing over which broom has better acceleration, the Nimbus 2000 or the Firebolt. The boys are going to race the two brooms from the ground to the top of the goals. Then they will switch brooms and replicate their trials. Test (independent) Variable:

Result (dependent) Variable:

Control Variables:

Define Replicate:

Independent variable: BROOM

Dependent variable: ACCELERATION

Control variable: same distance

Find the definition of replicate below

Explanation:

In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter. In this case, the independent variable is the BROOM.

The dependent variable is the variable that is measured in an experiment. It is the variable that responds to the independent variable. The ACCELERATION is the dependent variable in this case.

The control variable is the variable that is kept constant or unchanged throughout the experiment. In this case, the control variable is the SAME DISTANCE traveled for each broom.

A replicate is a repeated experiment with the expectance of a similar or consistent result. In this case, if the brooms are switched, the acceleration of each broom should be the same in the replicate result.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
