Question

this table shows four examples of experiments. four experiments person experiment lily measure the energy change in a compressed spring. astrid measure the energy change when rolling a ball downhill. henry measure the work being done when a dart is thrown. bob measure the work being done when a box is lifted to a shelf. which describes who will record their measurements in joules? lily and henry astrid and bob lily, astrid, henry, and bob astrid, henry, and bob

Explanation:

Step1: Recall the unit of energy and work

The SI - unit of energy and work is the joule. All the experiments listed involve either measuring energy change or work done.

Step2: Identify the people doing relevant measurements

Lily is measuring energy change in a spring, Astrid is measuring energy change of a rolling ball, Henry is measuring work done when a dart is thrown, and Bob is measuring work done when a box is lifted. Since energy change and work are measured in joules, all of them (Lily, Astrid, Henry, and Bob) will record their measurements in joules.

Answer:

Lily, Astrid, Henry, and Bob
