Mosquito repellent is sprayed on one arm and the other arm is not sprayed. The number of mosquito bites is counted after two hours. 1. Name the independent variable:
2. Name the dependent variable:

An independent variable is the variable that is changed or controlled to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. So in this case, we are controlling the mosquito repellent spray because we are putting it on one arm while the other no. We are trying to test the sprays effects on the bites to see if the bites will lessen or become more or not change at all so the independent variable is the mosquito repellent spray. They said that the number of Mosquito bites are counted after 2 hours so they are measured. That means that the dependent variable is the number of bites. The number of bites dependent on the spray to see if they lessened or had gotten more or nothing.

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this
