Answer:

False, assuming this is a true/false question.

Explanation:

Energy is converted from one form to another, not destroyed nor created.  The suns' energy comes for energy released in nuclear reactions. Energy consumed is converted to another form, such as plant and animal sugars and carbohydrates, where it is stored in the bonds among the elements.

Statement:

The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.

Explanation:

Problem 1

The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.

Reasons:

  • Using the mass pieces and the cup to find the weight of the orange is wrong approach.

     He can easily place the orange on the balance and read off the weight.

  • Centimeters is a unit of length. What length is he measuring and recording?

    The unit of weight is in newtons(N).

  • Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.

Problem 2

Rewriting to paragraph to correct the errors:

The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.
